The Milky Means might be a part of one thing even bigger than Laniakea

If you want to determine your place in the universe, start with your cosmic address. They live on Earth -> Solar System -> Milky Way -> Local Cluster -> Virgo Cluster -> Virgo Supercluster -> Laniakea. Thanks to new deep-sky surveys, astronomers now believe that all of these places are part of an even larger cosmic structure in the “neighborhood” called the Shapley Concentration.

Astronomers call the Shapley concentration the “basin of attraction.” This is a region loaded with mass that acts as an “attractor”. It is a region with many clusters and groups of galaxies and the largest concentration of matter in the local universe. All of these galaxies and dark matter give the concentration its gravitational influence. There are many such basins in the universe, including Laniakea. Astronomers are working to study them in more detail, which should help create a more accurate map of the largest structures in the universe.

A group led by University of Hawaii astronomer R. Brent Tully measured the motions of about 56,000 galaxies to understand these basins and their distribution in space. “Our universe is like a giant web in which galaxies lie along filaments and cluster at nodes where gravitational forces pull them together,” Tully said. “Just as water flows in watersheds, galaxies flow in cosmic basins of attraction. The discovery of these larger basins could fundamentally change our understanding of cosmic structure.”

Cosmic currents and mapping structures

Tully's team is called CosmicFlows and studies the movements of these distant galaxies in space. The team's “redshift” studies revealed a possible shift in the size and extent of our local galactic gravitational pull. We already know that we “live” in Laniakea, which is about 500 million light-years across. However, the movements of other clusters suggest that there is a larger “attractor” directing the cluster flow. The CosmicFlows data suggests that we could be part of the Shapley concentration, which could be ten times the volume of Laniakea. It is about half the size of the largest structure in space, the “Great Wall,” a chain of galaxies that stretches over 1.4 billion light-years.

The 2dF Galaxy Redshift Survey discovered several superclusters. Inside is the structure known as the Sloan Great Wall. Courtesy of the 2dF Galaxy Redshift Survey.

The Shapley concentration was first observed as a “cloud” in the constellation Centaurus in the 1930s by astronomer Harlow Shapley. This supercluster appears along the direction of movement of the local group of galaxies (where we live). For this reason, scientists speculated that it could influence the peculiar motion of our galaxy. Interestingly, the Virgo Supercluster (as well as the Local Group and the Milky Way) appears to be moving toward the Shapley concentration. The surveys that Tully and others are conducting should confirm this movement toward what she is attracted to.

Exploring ever larger structures in the universe

Where do these attractions come from? In some ways, they are as old as the universe and its cosmic web of matter, which Tully refers to. The seeds for the web and these basins of attraction were planted approximately 13.8 billion years ago. After the Big Bang, the young universe was in a hot, dense state. As it expanded and cooled, the density of the matter began to fluctuate. There were tiny differences in these density fluctuations. Think of them as the earliest “seeds” of galaxies, galaxy clusters, and even larger structures we see in the universe today.

As astronomers study the sky, they find evidence of all of these different structures. Now they have to explain it. The idea that the Shapley concentration is the large basin to which our Laniakea belongs means that current cosmological models do not fully explain its existence.

“This discovery presents a challenge: Our cosmic surveys may not yet be large enough to map the entire extent of these vast basins,” said UH astronomer Ehsan Kourkchi. “We still look through giant eyes, but even those eyes may not be big enough to capture the full picture of our universe.”

Measurement of attractors

The main player in all of these galaxies, clusters and superclusters is gravity. The more mass, the more gravity influences movements and distribution of matter. For these basins of attraction, Tully's research team examined their effects on the movements of galaxies in the region. The basins exert a kind of “tug of war” on the galaxies that lie between them. This affects their movements. In particular, redshift surveys like the ones Tully's team is conducting will map radial motion (along the line of sight), velocities (how fast they move), and other associated motions. By mapping the velocities of galaxies in our local universe, the team can define the region of space where each supercluster dominates.

Of course, these movements are difficult to define. That's why the team carries out different types of measurements. They don't just map the luminous matter in galaxies. You also have to take into account the suspected existence of dark matter. There are other complications too. For example, not all galaxies are the same – that is, they differ in their shape (morphology) and density of matter. Astronomers can get around this by measuring the so-called “galaxy velocity.” This is the difference between its actual speed and the expected “Hubble flow” speed (which reflects gravitational interactions between galaxies).

The results of the Tully team's surveys are expected to provide increasingly precise 3D maps of these regions of space. This includes their structures as well as their movements and speeds. These maps, in turn, should provide greater insight into the distribution of all matter (including cold dark matter) throughout the universe.

Air taxi firm Joby receives one other $500 million from Toyota

Flying taxis, once the subject of science fiction films, were widely expected to make a big splash by whizzing over the City of Light during Paris Olympics celebrations last summer – before being scrapped due to certification concerns became.

That doesn't stop Toyota from putting more money into air mobility.

The Japanese giant is making another $500 million investment in Joby, the California-based company that conducted the first test flight of an air taxi over the skies of a crowded US metropolis (New York City) last November. Just last month, Joby also signed an agreement with the United Arab Emirates that could allow commercial passenger services to begin in Dubai as early as 2025.

Plans for commercial operations in the US are also underway: Delta Air Lines is partnering with Joby to eventually offer air taxis as a perk to its travelers, while United Airlines is partnering with Archer Aviation.

Air taxis, also known as electric vertical take-off and landing (eVTOL) vehicles, promise a much faster, quieter and cleaner (carbon-free) mobility service compared to ground transport.

Joby says its electric air taxi is designed to carry a pilot and four passengers at speeds of up to 200 miles per hour. Some eVTOL vehicles are also designed for autonomous operation.

Toyota's interest in Joby began in 2019. With the latest tranche of funds, the Japanese giant has now invested almost $900 million to support the certification and commercial production of Joby's electric flying taxi.

Toyota says it is investing not only money, but also time and resources to share its knowledge of process planning, manufacturing and tool design with the Joby team in California. Last year, the two companies signed an agreement for Toyota to supply key propulsion and actuation components for Joby's aircraft.

Safety and certification processes remain the biggest hurdle to the full development of air taxi services, as the canceled Olympic flight of the German Volocopter demonstrated.

But many companies around the world, such as Hyundai and China's XPeng HT Aero, are also vying for a share of the air mobility market. According to consulting firm McKinsey, the market for ground taxi services and emailing is currently valued at $500 billion worldwide. And more than 20% of people who currently use these ground services can “definitely imagine” getting on air taxis.

Actual plans for air taxi operations in the US are still tied to airport-to-city service. But Joby, for its part, has been looking further into the future since acquiring Uber Elevate in 2020, hoping to one day pair its flying taxis with Uber's ride-hailing app.

Eli Lilly is constructing a $4.5 billion analysis and manufacturing middle

Eli Lilly will spend $4.5 billion to build a center aimed at finding better ways to make its drugs.

The facility, called Lilly Medicine Foundry, will house the development of new manufacturing methods with efficiency in mind. That strategy is already paying off with Lilly's obesity and weight loss drugs Mounjaro and Zepbound, and Lilly wants it to move forward with the rest of its pipeline.

The foundry serves a dual purpose: researching new manufacturing processes and then putting them into practice in the production of drugs for clinical trials. According to Lilly, the facility will be the first of its kind to combine research and production at a single location.

“The idea is to take molecules from a lab bench to the drug scale in a pharmacy, and this research and development site will do that work,” Eli Lilly Chief Executive Officer David Ricks said in an interview at the company’s headquarters Company in Indianapolis.

The center, scheduled to open in late 2027, will be equipped to produce small molecules, biologics and genetic medicines. It will be near a $9 billion manufacturing complex Lilly is building in Lebanon, Indiana, to make active pharmaceutical ingredients such as tirzepatide, the active ingredient in Mounjaro and Zepbound.

The active construction site's cranes and steel frames rise from the flat farmland about a 40-minute drive from Lilly's Indianapolis headquarters.

The investments are part of Lilly's plan to build on success with Mounjaro and Zepbound, which, along with Novo Nordisk's Ozempic and Wegovy, are riding a wave of popularity in so-called GLP-1 drugs.

Mounjaro and Zepbound are expected to bring in $50 billion alone by 2028 – nearly double the company's total full-year sales in 2022. That gives Lilly more freedom to invest, but also puts pressure on the company to produce more new drugs find and develop further to grow in the coming years.

Lilly is already planning its future beyond tirzepatide. The company also wants to develop additional drugs for Alzheimer's disease and other neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS).

“There are all these huge opportunities for improving human health that are hidden,” said Dr. Dan Skovronsky, Lilly's chief scientific officer. “In our industry, people usually like to see what's popular and then follow the leader. “So many other companies are now halting their various research projects to figure out how to catch up with us on obesity and Alzheimer’s disease.” OK, we're working on the next thing.

A sign with the company logo hangs in front of Eli Lilly's headquarters in Indianapolis, Indiana, on March 17, 2024.

Lilly wants to look for “breakthrough ideas” in areas where the company already has a foothold, such as oncology and immunology, but also in newer areas such as cardiovascular disease, chronic pain and hearing loss, Skovronsky said.

One area he and Ricks want to place particular emphasis on is neuroscience. Lilly has a long history between its antidepressant Prozac and its newly approved Alzheimer's drug Kisunla, but still sees a lot of work to do.

“Neuropsychology is a huge unmet need,” Ricks said. “Addiction and mental health, but also neurodegenerative diseases, so we are investing heavily there. And perhaps the progress we have made in obesity can help fund research in new areas.”

That doesn't mean Lilly is done with obesity.

More CNBC Health coverage

Ricks acknowledged that one drug cannot meet all needs and that Lilly must continue to advance the science. The company has 11 anti-obesity drugs in its pipeline with different mechanisms of action and delivery routes, he said. That includes two closely watched drugs in Phase 3 trials: an experimental pill called orforglipron and another injectable drug called retatrutide.

Lilly is investing in obesity wherever it makes sense, Ricks said, but he recognizes that other companies may be exploring new mechanisms that Lilly may not have done. He wants to see more pills, especially ones that can target multiple targets. He is also interested in technologies that allow injections to be administered less frequently, such as short interfering RNA.

Any new advances could help Lilly become the first trillion-dollar healthcare company. The company's shares have risen nearly 65% ​​in the past year, giving Lilly a market capitalization of about $840 billion.

Ricks downplays the significance of reaching the trillion-dollar mark, saying that for Lilly it would be an outcome, not a goal.

“We want to do valuable things, and when we are successful, we create value,” Ricks said. “That’s how we get a larger number.”

Lane Thomas' dwelling run pushes the Guardians previous the Tigers within the ALDS opener

CLEVELAND – Lane Thomas hit a three-run home run in a five-run outburst before Detroit got an out and the Cleveland Guardians unleashed their lights-out bullpen to complete a four-hitter in a 7-0 victory over the Tigers in an AL Division Series opener to be completed on Saturday.

Thomas' shot – in his first career postseason move – helped the Guardians hold off the Tigers, who stormed into the playoffs with a second-half surge before beating AL West champion Houston in the wild-card round defeated.

Tanner Bibee pitched 4⅔ innings before Guardians manager Stephen Vogt opened the door to baseball's best bullpen to finish off the Tigers. The relievers combined to pitch 4⅓ scoreless innings, creating the largest shutout victory margin in Cleveland's postseason history.

Editor's Tips

1 relative

“It started with the guys in front of me,” Thomas said.

Detroit struck out 13 times and didn't get a runner past first in the final four innings.

Cleveland's bullpen was as advertised. Rookie Cade Smith (1-0) replaced Bibee and struck out all four batters. Tim Herrin took care of the seventh, Hunter Gaddis took care of the eighth and Emmanuel Clase, who led the AL with 47 saves, took care of the ninth.

David Fry added a two-run double in the sixth inning for the AL Central champion Guardians, who didn't play for nearly a week with a first-round bye.

“It's incredible to come out day in and day out and do what they do, especially during the 162 season.” [games]“It shows what we have back there,” Thomas said.

Game 2 is Monday when the Tigers turn to Tarik Skubal, the favorite to win the AL Cy Young Award, to try to even win the best-of-five series.

The 2,327th Meeting between Detroit and Cleveland was the first between the franchises and Central Division rivals in the postseason.

After one inning it was almost over.

Tigers coach AJ Hinch has been making the right decisions for months as his young club moved into postseason eligibility with a record of 33-13 at the trade deadline on August 11th.

Hinch used his bullpen from the start in Game 1 and it backfired.

The Guardians sent nine batters to the plate in the first, with Thomas' moonshot into the left-field stands opening a 5-0 lead. Cleveland became the first team in AL postseason history to score five runs before recording an out.

Steven Kwan got it rolling with a leadoff double against Tigers starter Tyler Holton (0-1) and Fry walked. José Ramírez followed with a hard jump to third that Zach McKinstry misplayed on a mistake, allowing Kwan to score.

Josh Naylor's RBI single made it 2-0 and Hinch pulled Holton after just four batters to bring in Reese Olson – the play exploded within seconds.

Thomas, who batted just .143 with 33 strikeouts in his first month with Cleveland after being acquired from Washington in July, made his first postseason at-bat with the Guardians memorable.

He turned Olson's first pitch – a slider down the middle of the plate – and hurled it over the wall, sending the majority of the 33,548 fans at Progressive Field into a frenzy.

Bibee admitted to being nervous before the opening game and he showed it in the first game.

He gave up a one-out single and struck out Riley Greene with two outs, prompting a visit from pitching coach Carl Willis. Bibee gave Colt Keith the final out with a lazy fly on his 27th pitch.

Taking the mound in the second with a five-run lead helped Bibee settle in. The right-hander allowed four hits and struck out six.

TRAINER ROOM

Guardians: RHP Alex Cobb, a candidate to start Game 3, was added to the ALDS roster after ending the regular season on the injured list with a blister on his middle finger. Cobb's postseason experience — he beat Cleveland in the 2013 wild-card round with Tampa Bay — certainly helped his cause, plus he was a former teammate of Vogt's. Cobb was acquired from San Francisco in a July trade.

NEXT

Skubal led the AL in wins (18), ERA (2.39) and strikeouts (228). The left-hander is expected to face Guardians RHP Matthew Boyd, who spent eight seasons with the Tigers and remains close friends with Skubal.

Ukraine’s new F-16 simulator highlights a “paradigm shift” led by XR

To the average eye, augmented reality begins to look bleak. The Metaverse bombed, the Apple Vision Pro flopped, and Sony has all but given up on the PSVR.

Mark Zuckerberg finds it unfortunate that consumers rarely want to strap computers to their faces. But there is one place where business is booming: the military.

XR has become widespread in the armed forces since 2021, when Microsoft signed a contract with the US Army up to $21.9 billion (€19.6 billion). Under the agreement, the tech giant would develop training programs for HoloLens-based headsets.

Despite a shaky start – in the truest sense of the word Nauseous soldiers — The partnership continues to this day. But it might not be long: roughly 80 companies are now competing for the contract.

The

The latest rumors from the EU tech scene, a story from our wise old founder Boris and questionable AI art. It's free in your inbox every week. Register now!

As the market expands, new use cases have emerged. You can now find XR in countless military applications, from combat training to battlefield tactics to vehicles Exercises and helmet systems. And that's just on the ground.

Arguably the fastest-growing military application for XR is pilot training. There is an undisputed European champion in this segment: Varjo.

From its headquarters in Finland, Varjo (pronounced “var-yo”) is building a thriving synthetic flight training business. The company's CEO, Timo Toikkanen, says a “paradigm shift” has begun.

The trigger was the growing need for aircraft simulators. Advances in XR paved the way to compelling new systems.

One was recently delivered to Ukraine. It will support the country's newest air force: F-16 fighter jets.

Flight preparations

After years of lobbying Western allies, Ukraine finally received its first F-16 fighter jets in August. The delivery was a milestone for the country's air force, which had previously relied on Soviet-era jets.

F-16s add a powerful upgrade to the fleet. But there is a problem with the arrangement: Ukraine does not have enough pilots who can fly the planes.

Traditional solutions to this problem come with their own problems. Airplane training is extremely expensive, seating is limited, and courses often require long travel. The traditional alternative is dome simulators, but they also have high prices. They are also huge machines that require their own buildings.

XR can overcome these barriers. The simulators are cheaper than domes and can be operated in offices. They can also integrate systems from all armed forces. But their greatest strength today is their speed.

“The training time for a fighter pilot is reduced by 30 to 50%,” says Toikkanen. “If it costs millions every year, that’s a very significant change.”

Ukraine has an urgent need for this fast and affordable training. The new F-16s could intercept enemy jets and establish areas of air superiority – but only with enough pilots to fly them. To train them, the country recently acquired its first fully operational XR F-16 system.

Czech company Dogfight Boss built the simulator, while Varjo provided the XR technology.

After entering the cockpit, pilots learn the controls, refine their techniques and fly virtual missions.

The Ukrainian Air Force can then benefit from this. But for Varjo, the country is just a tiny addition to a booming global market.

“The F-16 in Ukraine is an example of a much broader phenomenon,” Toikkanen said. “And the phenomenon is that traditional methods of training pilots are being replaced by mixed reality technology.”

XR takes off

One of Varjo's closest partners is Aechelon Technology. The American company creates geo-specific visualizations of the real world that have been integrated into Varjo's XR system. Together, the partners produced headsets for the US Air Force.

“We are one of the big players in the USA. But Varjo is The players,” Aechelon co-founder Javier Castellar tells TNW.

Castellar estimates that Varjo has captured at least 95% of the XR flight training market. He calls the company “the Tesla of Finland.”

This reputation in military aviation has developed rapidly. A few years ago, XR was technically unable to replace air force simulators. Today, Varjo participates in over 80 military training programs throughout NATO territory. Orders for XRs, says Castellar, now outnumber those for domes by at least eight to one.

The reason for this turnaround is a major leap in technology.

Varjo's groundbreaking headset was the XR-4 series. Released last yearThe devices combine a 360-degree view of the synthetic environment with the cockpit interior. Castellar says the system “crossed a threshold of human vision.”

Inside the headset Foveated rendering Tracks the pilot's eyes and maximizes the resolution where he looks. By applying this technique, the XR-4 can increase visual quality while reducing computational effort. Dual 4K x 4K displays can then deliver photorealistic scenes at 90 frames per second.

To integrate the pilot's surroundings, two 40-megapixel cameras align the visual focus to the pilot's gaze. As your view moves from the digital environment to the physical cockpit, the pass-through system shifts your view from the virtual to the real. TNW did it Test the technology last year and found the transition seamless.

With increasing acceptance, new possibilities arise. “It’s not just a display system,” says Castellar. “It has a significant impact on defense.”

Fly higher

Modernizing modern aircraft is expensive. With domes, costs are reduced, but the changes still aren't cheap. They can also involve complex implementations.

XR promises a simpler solution. “The architecture can be continually adjusted as it becomes more of a software problem,” says Castellar.

The improvements are potentially endless. On an F-16 simulator, you could add night vision goggles, new weapon systems, or the latest aircraft helmet. All of these components can then be incorporated into the mission rehearsals.

But that only applies to airplanes. Varjo expects that XR will now spread across the armed forces and into complex military operations. The headsets will connect aircraft in the sky with ships at sea and vehicles on the ground. Numerous simulators will follow the same scenario. Each element is networked in an environment.

“You can’t practice that in real life,” says Toikkanen. “The only practice is to simulate.”

The software also offers advanced data analysis. They can measure a pilot's cognitive stress, reaction speed or direction of gaze. Training programs can be tailored to your needs.

The findings could even shape real military equipment. “You can get pilots to fly airplanes that don’t exist yet,” says Castellar. “You can experience the impact of performance on the battlefield and make design decisions based on that.”

This affordable adaptability creates a recurring business model. In the future, Castellar envisions a service similar to smartphone upgrade programs.

“I think it will generate profits in a sustainable way, which is unusual in this industry,” he says. “It’s usually a one-time purchase.”

As evidence of the benefits grows, Castellar expects adoption to increase rapidly. The defense market typically develops slowly. But as new technologies become more important, order numbers often increase.

They can also lead to new applications. Endless military machines could eventually follow the XR trajectory.

“These are no longer just training aids that you like to have,” says Castellar. “They become vital to the defense of any country.

Mom of 4 discovered responsible after her 4 sons died in home hearth

A court has convicted a woman of causing the deaths of her four young children in a house fire in London. Deveca RoseThe 30-year-old was taken to court on October 3 for leaving her two sets of twins home alone while she allegedly went shopping on December 16, 2021.

More information about Fire Day

Firefighters found twin brothers Leyton And Logan Hoath3, and Kyson And Bryson Hoath4, unconscious in an upstairs bedroom.

A person noticed the house was on fire after 7 p.m. and alerted a neighbor, who kicked in the front door to get to the children. PEOPLE reports that the fire in the downstairs living room was likely caused by a candle or a burning signature.

According to the BBC, the four children ran upstairs to call for help but were unable to escape, which ultimately led to their deaths.

In a police statement, Deveca claimed that a few days before the incident, she met a woman named Jade who was supposed to be supervising her children. On the night of the incident, Rose reportedly attempted to call “Jade” in front of police, using a phone number similar to her own. However, call records from Rose's cellphone did not reveal any contact information for the woman named “Jade,” PEOPLE explained. Furthermore, authorities have not located Jade and there is no trace of a relationship between her and Deveca.

CCTV footage obtained by police confirmed that Deveca had also left her house alone the day before the incident. Additionally, the Times noted that social workers determined the family needed help five months before the fire, but Deveca refused to provide assistance.

Details on Deveca Rose's sentencing and what's next?

According to The Guardian, Rose was convicted of four counts of involuntary manslaughter but was found not guilty of abandoning a child.

Detective Chief Inspector Samantha Townsend, from the Met's Specialist Crime Command, said Deveca Rose was the one who protected the four boys.

“Had she been in the house when the fire started, she may have been able to put it out or at least get the children to safety,” DCI Townsend added.

Authorities released Rose on bail on Oct. 3 and she will return to court on Nov. 15 for sentencing.

The mission to Jupiter's icy moon Europa begins on October 10th… superb work accomplished by Galileo over 400 years in the past on the most important planet in our photo voltaic system and its moons

overview

In the early 17th century, Galileo pointed his primitive telescope at Jupiter and saw tiny specks of light with no discernible features. What a difference 400+ years can make, as today's backyard telescopes can resolve the disk of Europe surprisingly well. Europa is now considered one of the most complex and fascinating worlds in the solar system. Cracks, ridges and chaotic terrain in the moon's icy crust may provide access to one of the largest oceans in the solar system – and a possible habitat for aquatic life. NASA's Europa Clipper spacecraft, scheduled to launch in a week on October 10, will conduct a detailed exploration of the lunar surface to help plan future missions, including a lander and perhaps even a submarine. Europa Clipper's main scientific goal is to find out whether there are places beneath Europa's surface that could harbor life.

Discussion about Europe and mission

Europa is a world that shows clear evidence of an ocean of liquid water beneath its icy crust, which could well harbor favorable conditions for life. NASA will launch a high-performance, radiation-tolerant spacecraft called Clipper into a long orbit around Jupiter to conduct repeated flybys of the icy moon. In fact, the plan is to conduct 49 flybys of Europa at closest approach altitudes of just 16 miles, flying over a different location on each flyby to scan nearly the entire moon. With its massive solar arrays and radar antennas, Europa Clipper will be the largest spacecraft NASA has ever developed for a planetary mission. The spacecraft needs large solar arrays to collect enough light for its energy needs because it operates in the Jupiter system, which is more than five times farther from the sun than Earth. The spacecraft will be about 16 feet (5 meters) tall. With its arrays deployed, the spacecraft has a wingspan of more than 100 feet and a dry mass (no fuel in the tanks) of 7,145 pounds. The launch date for this spacecraft is currently set for Thursday, October 10, with arrival at Jupiter in April 2030.

Because Europa is bathed in radiation trapped in Jupiter's magnetic field, Europa Clipper's payload and other electronic equipment will be enclosed in a thick-walled vault. This strategy of armoring up to Jupiter with a radiation vault was first developed and successfully used by NASA's Juno spacecraft. The walls of the vault – made of titanium and aluminum – serve as a radiation shield against most high-energy atomic particles, significantly slowing the degradation of the spacecraft's electronics.

For Europe to be habitable, it needs the essential building blocks of life, including carbon, hydrogen, oxygen and sulfur. Liquid water is essential to the complex chemistry that makes life on Earth possible. Many scientists predict that beneath Europa's surface is a salty ocean that contains more water than all of Earth's oceans combined. While Jupiter's icy moon is far from the sun, Europa gets the energy to sustain life from Jupiter's strong gravity, which creates tides that stretch and tug on the moon, generating heat. One of the most important measurements from the Galileo mission, which previously explored Europa, showed how Jupiter's magnetic field was disturbed in the area around Europa. The measurement strongly suggested that in Europa a special magnetic field is created (induced) by a deep layer of an electrically conductive liquid (such as salt water) beneath the surface, which interacts with Jupiter's strong magnetic field.

The amazing work of Galileo

When Italian astronomer Galileo Galilei looked at the planet Jupiter through his newly improved homemade 20x telescope on January 7, 1610, he noticed three more points of light near the planet and initially believed they were distant stars. As he observed them over several nights, he noticed that they appeared to be moving in the wrong direction with respect to the background stars, remaining close to Jupiter but changing their positions relative to each other. He later observed a fourth star near the planet with the same unusual behavior. On January 15, Galileo correctly concluded that they were not stars at all but rather moons orbiting Jupiter, providing strong evidence for the Copernican theory that most celestial objects did not revolve around the Earth . In March 1610, Galileo published his discoveries of Jupiter's moons and other celestial observations in a book entitled Siderius Nuncius (The Starry Messenger).

As their discoverer, Galileo had the naming rights to Jupiter's moons. He suggested naming them after his patrons, the Medici, and astronomers called them the Medici stars for much of the 17th century, although in his own notes Galileo referred to them in order of sequence with the Roman numerals I, II , III and IV denote distance from Jupiter. Astronomers still refer to the four moons as the Galilean satellites in honor of their discoverer. German astronomer Johannes Kepler suggested naming the satellites after mythological figures associated with Jupiter, namely Io, Europa, Ganymede and Callisto, but his idea failed to gain traction for over 200 years. Scientists did not discover additional satellites around Jupiter until American astronomer EE Barnard discovered Jupiter's fifth moon Amalthea in 1892, which was much smaller than the Galilean moons and orbited the planet closer than Io. It was the last satellite in the solar system to be found through visual observation – all subsequent discoveries were made through photography or digital imaging. To date, astronomers have identified 79 satellites orbiting Jupiter.

CVS is contemplating a break up. This is why that might be dangerous

A sign outside of a CVS pharmacy store on February 07, 2024 in Miami, Florida.

It’s time for a wellness check at CVS Health.

Shares of the company are down more than 20% this year as it grapples with higher-than-expected medical costs in its insurance unit and pharmacy reimbursement pressure, among other issues.

As it seeks to claw back faith with Wall Street, the company is considering breaking itself up.

CVS has engaged advisors in a strategic review of its business, CNBC reported Monday. One option being weighed is splitting up its retail pharmacy and insurance units. It would be a stunning reversal for the company, which has spent tens of billions of dollars on acquisitions over the last two decades to turn itself into a one-stop health destination for patients.

Some analysts contend that a breakup of CVS would be challenging and unlikely. 

CVS risks losing customers and revenue if it splits up its vertically integrated business segments, which includes health insurer Aetna and the major pharmacy benefits manager Caremark. That could translate to more lost profits for a health-care giant that has slashed its full-year 2024 earnings guidance for three consecutive quarters. 

“There really is no perfect option for a split,” said eMarketer senior analyst Rajiv Leventhal, who believes a breakup is still a possibility. “If that does happen, one side of the split becomes really successful and prosperous, and the other would significantly struggle.”

Notably, CVS executives on Monday met with major shareholder Glenview Capital to discuss how to fix the flailing business and recover its stock, CNBC previously reported. But Glenview on Tuesday denied rumors that it is pushing to break up the company.

If CVS stays intact, CEO Karen Lynch and the rest of the management team will have to execute major changes to address what industry experts say are glaring issues battering its bottom line and stock price.

The company has already undertaken a $2 billion cost-cutting plan, announced in August, to help shore up profits. CVS on Monday said that plan involves laying off nearly 3,000 employees.

Some analysts said the health-care giant must prioritize recovering the margins in its insurance business, which they believe is the main issue weighing on its stock price and financial guidance for the year. That pressure drove a leadership change earlier this year, with Lynch assuming direct oversight of the company’s insurance unit in August, displacing then-President Brian Kane.

CVS’ management team and board of directors “are continually exploring ways to create shareholder value,” a company spokesperson told CNBC, declining to comment on the rumors of a breakup. 

“We remain focused on driving performance and delivering high quality healthcare products and services enabled by our unmatched scale and integrated model,” the spokesperson said in a statement. 

Investors may get more clarity on the path forward for the company during its upcoming earnings call in November.

The Caremark question

Some analysts said the likelihood of CVS separating its retail pharmacy and insurance segments is low given the synergies between the three combined businesses. Separating them could come with risks, they added. 

“The strategy itself is still vertical integration,” Jefferies analyst Brian Tanquilut told CNBC. “The execution might not have been the greatest, but I think it’s a little too early to really conclude that it’s a broken strategy.”

Many of CVS’ clients contract with the company across its three business units, according to Elizabeth Anderson, analyst at Evercore ISI. Anderson said “carving out and pulling apart a whole contract” in the event of a breakup might be “quite difficult operationally” and lead to lost customers and revenue. 

Pharmacy benefits managers like CVS’ Caremark sit at the center of the drug supply chain in the U.S., negotiating drug rebates with manufacturers on behalf of insurers, creating lists of preferred medications covered by health plans and reimbursing pharmacies for prescriptions. 

That means Caremark also sits at the intersection of CVS’ retail pharmacy operation and its Aetna insurer, boosting the competitive advantage of both of the businesses. In the event of a breakup, it’s not clear where Caremark would fall.

Separating Caremark from Aetna would put the insurance business at a competitive disadvantage since all of its largest rivals, including UnitedHealth Group, Cigna and Humana, also have their own PBMs, said eMarketer’s Leventhal. 

But Caremark, in some cases, also funnels drug prescriptions to CVS retail pharmacies, he said. That has helped the company’s drugstores gain meaningful prescription market share over its chief rival, Walgreens, which has been struggling to operate as a largely stand-alone pharmacy business. 

CVS is the top U.S. pharmacy in terms of prescription drug revenue, holding more than 25% of the market share in 2023, according to Statista data released in March. Walgreens trailed behind with nearly 15% of that share last year. 

Now, CVS drugstores must maintain an edge over competitors at a time when the broader retail pharmacy industry faces profitability issues, largely due to falling reimbursement rates for prescription drugs. Increased competition from Amazon and other retailers, inflation, and softer consumer spending are making it more difficult to turn a profit at the front of the store. Meanwhile, burnout among pharmacy staff is also putting pressure on the industry. 

CVS’ operating margin for its pharmacy and consumer wellness business was 4.6% last year, up from 3.3% in 2022 but down from 8.5% in 2019 and 9.9% in 2015.

CVS and Walgreens have both pivoted from years of endless retail drugstore store expansions to shuttering hundreds of locations across the U.S. CVS is wrapping up a three-year plan to close 900 of its stores, with 851 locations shuttered as of August.

The rocky outlook for retail pharmacies could make it difficult for CVS to find a buyer for its drugstores in the event of a split, according to Tanquilut. He said a spinoff of CVS’ retail pharmacies would be more likely.

“There’s a reason they’re cutting down stores. Why break it up when the relationship between Caremark and CVS retail is what keeps it outperforming the rest of the pharmacy peer group?” Tanquilut said. 

Fate of Oak Street Health

CVS has other assets that would need to be distributed in the event of a breakup. 

That includes two recent acquisitions: fast-growing primary care clinic operator Oak Street Health, which the company purchased for $10.6 billion last year, and Signify Health, an in-home health-care company that CVS bought for about $8 billion in 2022. Those deals aimed to build on CVS’ major push into health care – a strategy that Walgreens and other retailers have also pursued over the last few years. 

Oak Street Health could theoretically be spun out with Aetna in the case of a split, Mizuho managing director Ann Hynes wrote in a research note Tuesday.

The primary care clinic operator complements Aetna’s Medicare business because it takes care of older adults, offering routine health screenings and diagnoses, among other services. CVS also sells Aetna health plans that offer discounts when patients use the company’s medical care providers. 

But CVS has also started to integrate Oak Street Health with its retail pharmacies. The company has opened those primary care clinics side by side with some drugstore locations in Texas and Illinois, with plans to introduce around two dozen more in the U.S. by the end of the year. 

Several companies, including Amazon, Walmart, CVS and Walgreens, are feeling the pain from bets on primary care. That’s because building clinics requires a lot of capital, and the locations typically lose money for several years before becoming profitable, according to Tanquilut. 

Walgreens could potentially exit that market altogether. The company said in a securities filing in August it is considering a sale of its primary care provider VillageMD.

But Tanquilut said it may not make sense for CVS to sell Oak Street Health or Signify Health because “they’re actually hitting their numbers.” 

Signify saw 27% year-over-year revenue growth in the second quarter, while Oak Street sales grew roughly 32% compared with the same period last year, reflecting strong patient membership, CVS executives said in an earnings call in August.

Oak Street ended the quarter with 207 centers, an increase of 30 from last year, executives added. 

“Why get rid of them when they’re still strategic in nature?” Tanquilut told CNBC, adding that it would be difficult to find a buyer for Oak Street given the challenging market for primary care centers.

Improving the insurance unit

If CVS doesn’t undergo a breakup, the “single best value-creating opportunity” for the company is addressing the ongoing issues on the insurance side of the business, according to Leerink Partners analyst Michael Cherny. 

He said the segment’s performance has fallen short of expectations this year due to higher-than-expected medical costs — by far the biggest hit to the company’s financial 2024 guidance and stock performance, he said. Cherny said he is confident the issue is “fixable,” but it will depend on whether CVS can execute the steps it has already outlined to improve margins in its insurance unit next year. 

Aetna includes plans for the Affordable Care Act, Medicare Advantage and Medicaid, as well as dental and vision. Medical costs from Medicare Advantage patients have jumped over the last year for insurers as more seniors return to hospitals to undergo procedures they had delayed during the Covid-19 pandemic, such as hip and joint replacements. 

Medicare Advantage, a privately run health insurance plan contracted by Medicare, has long been a key source of growth and profits for the broader insurance industry. More than half of Medicare beneficiaries are enrolled in those plans as of 2024, enticed by lower monthly premiums and extra benefits not covered by traditional Medicare, according to health policy research organization KFF. 

But investors are now concerned about the skyrocketing costs from Medicare Advantage plans, which insurers warn may not come down anytime soon.

Cherny said CVS faced a “double whammy” in Medicare Advantage this year, grappling with excess membership growth at a time when many seniors are using more benefits. 

In August, CVS also said its lowered full-year outlook reflected a decline in the company’s Medicare Advantage star ratings for the 2024 payment year. 

Those crucial ratings help patients compare the quality of Medicare health and drug plans and determine how much an insurer receives in bonus payments from the Centers for Medicare & Medicaid Services. Plans that receive four stars or above get a 5% bonus for the following year and have their benchmark increased, giving them a competitive advantage in their markets.

Last year, CVS projected it would lose up to $1 billion in 2024 due to lower star ratings, the company disclosed in a securities filing. 

But things may start to look up in 2025. 

For example, one of the company’s large Medicare Advantage contracts regained its four-star rating, which will “create an incremental tailwind” in 2025, CVS executives said in August. 

“We’re giving them the benefit of the doubt because we know that the stars rating bonus payments will come back in 2025,” Tanquilut said. 

During a conference In May, CVS said it would pursue a “margin over membership” strategy: CVS CFO Tom Cowhey said the company is prepared to lose up to 10% of its existing Medicare members next year in an effort to get its margins “back on track.” 

The company will make significant changes to its Medicare Advantage plans for 2025, such as increasing copays and premiums and cutting back certain health benefits. That will eliminate the expenses tied to those benefits and drive away patients who need or want to use them. 

Those actions will help the company achieve its target of 100- to 200-basis-points margin improvement in its Medicare Advantage business, CVS executives said in August.

The solar unleashes its strongest glow throughout this cycle

Yesterday the sun released a huge solar flare that is heading towards Earth! There's no need to worry as it's nowhere near as big as the Carrington event of 1859, but it's big enough to give us some amazing auroras.

Large solar flares occur at regular intervals. Literally, because the sun goes through an 11-year cycle of lower and higher activity. Right now the Sun is near the maximum of a cycle, so we are seeing lots of sunspots and solar flares. When astronomers first studied the cycle, they could only measure the number of sunspots at any given time. Solar flares were largely invisible to early telescopes. But now, with orbiting observatories like the Solar Dynamics Observatory, we can capture images of solar flares in real time. Astronomers now categorize the strength of solar flares based on the intensity of the X-rays they emit, called the x-class. The categories are numbered by ability level, with each category being twice as high as the previous one. For example, an X2 flare is twice as powerful as an X1 and half as powerful as an X3.

This latest flare is rated as X9, which is much stronger than most solar flares. But stronger events have reached Earth before. In 1989, an X15 event in Quebec triggered a regional blackout. In November 2003, the Sun released an X28 solar flare, but it mostly missed Earth. The Carrington event of 1859 occurred before astronomers developed the x-class classification, but is estimated to be around X45. While this outbreak is huge, it does not pose a serious threat to our electrical infrastructure.

What it will offer, however, is an aurora light show. When the charged particles released by the flare reach Earth's magnetosphere, many of them are captured by our magnetic field and spiral along the field lines to hit Earth's atmosphere in the polar regions. The impact triggers the subtle and beautiful light shows known as aurora. If you live far enough from the equator, you may be able to see them in the next few days. To find out your chances, you can take a look at the National Oceanic and Atmospheric Administration's Space Weather Prediction Center.

Pete Alonso's dwelling run within the prime of 9 sends Mets into the NLDS via Brewers

  • Jesse Rogers, ESPN staff writerOctober 3, 2024, 10:16 p.m. ET

      Jesse joined ESPN Chicago in September 2009 and covers MLB for ESPN.com.

MILWAUKEE – New York Mets star Pete Alonso struck out three runs and hit Devin Williams, the Milwaukee Brewers' closer, in the ninth inning on Thursday night as they face the Philadelphia Phillies.

With his team trailing 2-0, Alonso hit a 3-1 changeup to right field and stunned the home crowd at American Family Field as the Mets won a wild first-round series, two games to one against the Brewers.

“I was just looking for something off the plate,” Alonso said after the 4-2 win in which Jesse Winker scored a game-winning run. “I just really wanted to hit something hard across most of the field. I’m really glad I capitalized on it, really happy I capitalized on it.”

“It’s a really special moment.”

Alonso was 1 for 11 in the series before his big home run, including a double play after tripping over his bat while running to first base in Game 2. But he shook it all off and decided to move on to the next bit rather than dwell on his struggles. According to ESPN Research, he became the first major league player to hit a home run while trailing in the ninth inning or later of a winner-take-all postseason game.

A walk from Francisco Lindor, followed by a later single from Brandon Nimmo, set the stage for Alonso. He didn't miss his pitch.

“Especially in these big games you have to take the next step and make a positive impact, stay within yourself and do your best,” Alonso said.

Teammate JD Martinez added: “Everyone kind of felt like he was due. It's a big monkey of his. It was huge to get us up. … He did a great job and didn't do too much. Just point from A to B.

The blast came not long after the Brewers scored the game's first runs in the bottom of the seventh, on home runs by pinch hitter Jake Bauers and right fielder Sal Frelick. They came on two pitches in a row and sent Brewers fans into a frenzy.

It didn't take long.

The back-and-forth nature of the game mirrored that of the series as a whole. According to ESPN Research, in the last five postseasons, teams have taken a 39-2 eighth-inning lead with a chance to win a playoff series. The two losses came on Wednesday (the Mets) and Thursday (the Brewers) when each team blew the lead.

“It was a great series,” Mets manager Carlos Mendoza said. “I’m so proud of this team.”

Alonso's heroics followed a masterful performance from Mets starter Jose Quintana, who pitched six shutout innings. He and Brewers rookie Tobias Myers battled each other pitch for pitch and gave up no runs during the game.

“Tobias put zeros, so I knew I had to do it,” Quintana said, drenched in champagne from the Mets’ celebration. “Then Pete did his thing at exactly the right time. I’m so proud of him.”

Alonso will be a free agent after the season, which has been extended for at least three more games. He has played in all 165 games the Mets have appeared in this year, hitting 34 home runs during the regular season and now one big home run in the postseason.

Despite being available every day, Alonso didn't have his best year as his OPS fell to a career-low .788. He will still be wanted in November.

Meanwhile, in the ninth inning, Mets owner Steve Cohen anxiously watched on a clubhouse television as his first baseman hit Williams to the deep, hearing the crowd before seeing the home run.

“It was a delay,” Cohen said with a laugh. “But man, he got through it. So proud of him.”

Cohen said similar things about his team, which played a regular-season doubleheader on Monday to get into the postseason, then won Game 1 in Milwaukee on Tuesday before losing on Wednesday and ultimately winning the series on Thursday.

How about this graduation! Hollywood couldn't write a better script. I'm so proud of this team. On to Philly

“It feels like we’ve been going for a month,” Martinez joked.

The Mets will continue that journey, playing Games 1 and 2 of the best-of-five division series in Philadelphia on Saturday and Sunday.

New York went 6-7 against the Phillies in the regular season and finished six games behind them in the division standings. According to ESPN Research, the 1,081 all-time meetings between the teams are the most between two franchises without a playoff matchup since 1962.

Without Alonso's home run there will never be a duel.

“We support each other here,” he said. “Tonight it was my turn. Tomorrow belongs to someone else.”
