Artemis Astronauts Enter Moon's Gravitational Pull, Catch First Glimpses of Far Side (nbcnews.com) 88

NASA's Artemis astronauts are now entering "the lunar sphere of influence," reports NBC News, "meaning the pull of the moon's gravity will become stronger than Earth's." Now as they begin their swing around the moon, the Artemis astronauts "are chasing after Apollo 13's maximum range from Earth," reports the Associated Press, hoping to beat its distance from Earth by more than 4,100 miles (6,600 kilometers).

They'll begin their six-hour lunar flyby 14 hours from now (at 2:45 p.m. ET Monday). But in a space-to-earth interview Saturday with NBC News, the astronauts were already describing their first glimpses of the edge of the far side: [NASA astronaut Christina Koch realized] it looked different from what she was accustomed to on Earth. "The darker parts just aren't quite in the right place," she said. "And something about you senses that is not the moon that I'm used to seeing...."

[Astronaut Reid] Wiseman called the flight a "magnificent accomplishment" and said the astronauts' ability to gaze at both Earth and the moon from their spacecraft has been "truly awe-inspiring." "The Earth is almost in full eclipse. The moon is almost in full daylight, and the only way you could get that view is to be halfway between the two entities," he said... And while the early photos of Earth and the moon that [Canadian astronaut Jeremy] Hansen and his colleagues have beamed back have been spectacular, the Canadian astronaut said they pale in comparison to the real deal outside their capsule's windows. "I know those photos are amazing," he said, "but let me assure you, it is another level of amazing up here."

And their upcoming six-hour lunar flyby "promises views of the moon's far side that were too dark or too difficult to see by the 24 Apollo astronauts who preceded them," notes the Associated Press: A total solar eclipse also awaits them as the moon blocks the sun, exposing snippets of shimmering corona.... At closest approach, they will come within 4,070 miles (6,550 kilometers) of the moon. Because they launched on April 1, the rendezvous won't have as much of the far lunar side illuminated as other dates would have. But the crew still will be able make out "definite chunks of the far side that have never been seen" by humans, said NASA geologist Kelsey Young, including a good portion of Orientale Basin.

They'll call down their observations as they photograph the gray, pockmarked scenes. There's a suite of professional-quality cameras on board, and each astronaut also has an iPhone for more informal, spur-of-the-minute picture-taking... Orion will be out of contact with Mission Control for nearly an hour when it's behind the moon. The same thing happened during the Apollo moonshots. NASA is relying on its Deep Space Network to communicate with the crew, but the giant antennas in California, Spain and Australia won't have a direct line of sight when Orion disappears behind the moon for approximately 40 minutes...

Once Artemis II departs the lunar neighborhood, it will take four days to return home. The capsule will aim for a splashdown in the Pacific near San Diego on April 10, nine days after its Florida launch. During the flight back, the astronauts will link up via radio with the crew of the orbiting International Space Station. This is the first time that a moon crew has colleagues in space at the same time and NASA can't pass up the opportunity for a cosmic chitchat.

Artemis II Astronauts Pass 100,000 Miles From Earth On Voyage To the Moon 80

The Artemis II crew has passed 100,000 miles from Earth and is now on a "free-return" path around the moon after a successful "translunar" injection burn. "Ladies and gentlemen, I am so, so excited to be able to tell you that for the first time since 1972 during Apollo 17, human beings have left Earth orbit," NASA's Dr Lori Glaze told a news conference. The Guardian reports: The astronauts -- the Americans Reid Wiseman, Victor Glover and Christina Koch, and a Canadian, Jeremy Hansen -- spent their first day in space performing checks on the spacecraft, which had never carried humans before. Later they had time to speak to US TV networks. "I've got to tell you, there is nothing normal about this," Wiseman told ABC News from the cramped interior of the capsule. "Sending four humans 250,000 miles away is a herculean effort, and we are now just realising the gravity of that."

Orion will travel about 4,000 miles (6,400km) beyond the moon before turning back, providing unprecedented and illuminated views of the lunar far side. If all proceeds smoothly, the astronauts will set a record by venturing farther from Earth than any human before -- more than 250,000 miles. The mission is part of a longer-term plan to repeatedly return to the moon, with the aim of establishing a permanent base that will offer a platform for further exploration.
After the final engine burn, NASA said Wiseman took two "spectacular" images of Earth.

The first photo, called Hello, World, "shows the vast expanse of blue that is the Atlantic Ocean, framed by a thin glow of the atmosphere as the Earth eclipses the Sun and green auroras at either pole," reports the BBC. Another photo shows the view of Earth from inside the Orion spacecraft.

DOJ Charges Super Micro Co-Founder For Smuggling $2.5 Billion In Nvidia GPUs To China 33

Longtime Slashdot reader AmiMoJo shares a report from CNN: The co-founder of Super Micro Computer and two others were charged with diverting $2.5 billion worth of servers with Nvidia's artificial intelligence chips to China, in violation of U.S. laws barring exports to that country without a license. Yih-Shyan Liaw, known as Wally; Ruei-Tsang Chang, known as Steven; and Ting-Wei Sun, known as Willy, were charged with conspiring to violate export control laws, smuggling goods from the U.S. and conspiring to defraud the U.S.

Liaw, who co-founded Super Micro Computer and served on its board of directors, was arrested Thursday in California and released on bail. Sun, a contractor, is held awaiting a detention hearing. Chang, who worked in the Taiwan office of Super Micro, remains at large. [...] According to the indictment, the men used a pass-through company based in Southeast Asia to place orders to obscure that the servers would end up in China. The men worked with executives at the pass-through company to provide false documents to the server manufacturer to further the deception, the indictment said. They used a shipping and logistic company to repackage the servers into unmarked boxes to conceal their contents before they were shipped to China.

To deceive the manufacturer's auditors, who checked the pass-through company for compliance with export laws, the men allegedly used "dummy" nonworking copies of the servers when the actual servers were on their way to China. Two of the defendants allegedly worked to stage the dummy servers at a warehouse rented by the pass-through company, according to the indictment. Sun took photos and videos of the staged servers to one of the compliance auditors who instead of conducting the audit was "off-site enjoying entertainment paid for" by the pass-through company, according to the indictment. In another instance, prosecutors said surveillance cameras documented individuals using hair dryers to remove labels and add labels and serial number stickers to the boxes and dummy servers.
Super Micro said it's fully cooperating with the investigation, but that hasn't prevented its stock from plunging. It's down nearly 30% following the news.

The company issued the following statement: "The conduct by these individuals alleged in the indictment is a contravention of the Company's policies and compliance controls, including efforts to circumvent applicable export control laws and regulations. Supermicro maintains a robust compliance program and is committed to full adherence to all applicable U.S. export and re-export control laws and regulations."

Chuck Norris Dies At 86 (nytimes.com) 160

Longtime Slashdot reader SchroedingersCat writes: Chuck Norris, known for his roles in action films and as Texas Ranger Cordell Walker on the TV show "Walker, Texas Ranger," passed away on March 19, leaving behind a legacy of inspiring millions around the world. He was 86.

He became Internet phenomenon after "Chuck Norris Facts" went viral online with such wildly hyperbolic statements as, "Chuck Norris had a staring contest with the sun -- and won," and, "When Chuck Norris does push-ups, he doesn't push himself up, he pushes the Earth down."

His death was announced by his family through his official Instagram account, but no further details were immediately available. He was hospitalized earlier that day in Hawaii after experiencing a medical emergency, the family said.

As OpenClaw Enthusiasm Grips China, Kids and Retirees Alike Raise 'Lobsters' 33

An anonymous reader quotes a report from Reuters: Fan Xinquan, a retired electronics worker in Beijing, has recently started raising a "lobster," hoping that the AI agent he has been training can help organize his specialized industry knowledge better than chatbots like DeepSeek. "OpenClaw can actually help you accomplish many practical things," the 60-year-old said at a recent event hosted by AI startup Zhipu to teach people how to use and train the AI agent, which has gone viral in China, with its various local versions earning the "lobster" nickname.

In the past month, OpenClaw, which can connect several hardware and software tools and learn from the data produced with much less human intervention than a chatbot, has captured the imaginations of many in China, from retirees looking for side income to AI firms hoping to generate new revenue streams. [...]

Huang Rongsheng, chief architect at Baidu's smart device unit Xiaodu, said at an event on Tuesday that parent group chats for his daughter's primary school class have become overwhelmed by OpenClaw discussions. "My daughter came to me and asked: Dad, I see you raising a lobster every day," he said. "Can I have one too?" Bai Yiyun, another attendee at the Zhipu event, said she hopes to use the agent to start a side hustle during her retirement.
"If DeepSeek marked a milestone for open-source large language models, then OpenClaw represents a similar turning point for open-source "agents," said Wei Sun, chief AI analyst at Counterpoint Research.

China Is Helping Drive Cuba's Solar Boom (washingtonpost.com) 151

AleRunner writes: "China is helping Cuba race to capture renewable solar energy as the United States imposes an effective oil blockade on the Caribbean island, creating its worst energy crisis in decades," reports The Washington Post. Later in the article, it states that "China's decades-long push into clean energy technology is now helping to protect it from the soaring oil and gas crisis spurred by Trump's war against Iran," and that "Chinese exports of solar equipment to Cuba skyrocketed from about $5 million in 2023 to $117 million in 2025 and show no sign of stopping." According to researchers from Ember, solar could be responsible for as much as 10% of Cuba's electricity generation. "That would be among the fastest expansions of solar energy anywhere [...] and place Cuba ahead of most countries -- including the U.S. -- in the share of electricity generated by sun power," the report says.

As the Iran war drives energy prices higher, countries around the world are working overtime to reduce their reliance on fossil fuels. China sees this as a big opportunity. "Chinese authorities have made clear that they intend to replicate what they're doing in Cuba elsewhere," reports the Washington Post.

Are U.S. Utilities Trying to Delay Easy-to-Use Solar 'Balcony' Panels? (npr.org) 120

Plug-in (or "balcony") solar panels can also be hung out a window or be set up in a backyard, reports NPR. They channel energy from the sun straight into a home's electrical outlet, generating enough electricity to power a refrigerator or microwave while "displacing electricity that otherwise would come in from the grid..."

But what's holding up their adoption in America? For the panels to become more widely available in the U.S., state lawmakers are proposing bills that eliminate complicated utility connection agreements, which are required for larger rooftop solar installations and, most utilities say, should apply to plug-in solar too. Those agreements, along with permitting and other installation costs, can double the price of solar panels. Utah enacted the first law, last May, supporting plug-in solar, and now some 30 pieces of similar legislation have been introduced around the United States. [And Virginia seems poised to pass a similar law.]

But the drive toward plug-in solar is facing pushback from electric utilities. They are raising safety concerns and prompting legislators to delay votes on the bills. So far, utilities have won over lawmakers in five states and convinced them to delay votes on plug-in solar bills... Plug-in solar advocates say that safety concerns about the new technology have been addressed and that utilities are really just worried about losing business, because every kilowatt-hour generated by a plug-in solar panel is one less the utility sells to a customer... There are safety risks with any electrical appliance, and it's true that plug-in solar panels present some unique problems. But safety experts also say those issues can be managed....

German utilities expressed many of the same concerns nearly a decade ago when plug-in solar started to become popular in Germany. But with more than a million systems installed, no safety incidents have been reported for customers who used the panels as instructed, according to a research paper funded by the U.S. Department of Energy.

Scientists Just Doubled Our Catalog of Black Hole and Neutron Star Collisions (space.com) 26

Colliding black holes were detected through spacetime ripples for the first time in 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO), notes Space.com: Since then, LIGO and its partner gravitational wave detectors Virgo in Italy and KAGRA (Kamioka Gravitational Wave Detector) in Japan have detected a multitude of gravitational waves from colliding black holes, merging neutron stars, and even the odd "mixed merger" between a black hole and a neutron star... During the first three observing runs of LIGO, Virgo and KAGRA, scientists had only "heard" 90 potential gravitational wave sources.
But now they've published new data from the LIGO-Virgo-KAGRA (LVK) Collaboration that includes 128 more gravitatational wave sources — some incredibly distant: [Gravitational-Wave Transient Catalog-4.0, or GWTC-4] was collected during the fourth observational run of these gravitational wave detectors, which was conducted between May 2023 and Jan. 2024... Excitingly, GWTC-4 could technically have been even larger, as around 170 other gravitational wave detections made by LIGO, Virgo and KAGRA haven't yet made their way into the catalog.

One aspect of GWTC-4 that really stands out is the variety of events that created these signals. Within this catalog are gravitational waves from mergers between the heaviest black hole binaries yet, each about 130 times as massive as the sun, lopsided mergers between black holes with seriously mismatched masses, and black holes that are spinning at incredible speeds of around 40% the speed of light. In these cases, scientists think the extreme characteristics of the black holes involved in these mergers are the result of prior collisions, providing evidence of merger chains that explain how some black holes grow to masses billions of times that of the sun... GWTC-4 also includes two new mixed mergers involving black holes and neutron stars.

[LVK member Daniel Williams, of the University of Glasgow in the U.K., said in their statement] "We are really pushing the edges, and are seeing things that are more massive, spinning faster, and are more astrophysically interesting and unusual." The catalog also demonstrates just how sensitive the LVK detectors have become. Some of the neutron star mergers occurred up to 1 billion light-years away, while some of the black hole mergers occurred up to 10 billion light-years away.

Einstein's theory of general relativity can be tested with these detections, and "So far, the theory is passing all our tests," says LVK member Aaron Zimmerman, of the University of Texas at Austin. "But we're also learning that we have to make even more accurate predictions to keep up with all the data the universe is giving us." And LVK member Rachel Gray, a lecturer at the University of Glasgow, says "every merging black hole gives us a measurement of the Hubble constant, and by combining all of the gravitational wave sources together, we can vastly improve how accurate this measurement is."

In short, says LVK member Lucy Thomas of the California Institute of Technology (Caltech), "Each new gravitational-wave detection allows us to unlock another piece of the universe's puzzle in ways we couldn't just a decade ago."

Daylight Saving Time Ritual Continues. But Are There Alternatives? (apnews.com) 160

Would you move sunrise to 9 a.m. in Detroit? Or to 4:11 a.m. in Seattle...

Though both options have problems, "There's no law we can pass to move the sun to our will," argues the president of the nonprofit "Save Standard Time". The Associated Press explains why America remains stuck in that annual ritual making clocks "spring forward, fall backward..." The U.S. has tinkered with the clock intermittently since railroads standardized the time zones in 1883. So has a lot of the world. About 140 countries have had daylight saving time at some point; about half that many do now. About 1 in 10 U.S. adults favor the current system of changing the clocks, according to an AP-NORC poll conducted last year. About half oppose that system, and some 4 in 10 didn't have an opinion.

If they had to choose, most Americans say they would prefer to make daylight saving time permanent, rather than standard time. ince 2018, 19 states — including much of the South and a block of states in the northwestern U.S. — have adopted laws calling for a move to permanent daylight saving time. There's a catch: Congress would need to pass a law to allow states to go to full-time daylight saving time, something that was in place nationwide during World War II and for an unpopular, brief stint in 1974. The U.S. Senate passed a bill in 2022 to move to permanent daylight saving time. A similar House bill hasn't been brought to a vote.

U.S. Rep. Mike Rogers, a Republican from Alabama who introduces such a bill every term, said the airline industry, which doesn't want the scheduling complexity a change would bring, has been a factor in persuading lawmakers not to take it up. U.S. Rep. Greg Steube, a Florida Republican, is proposing another approach. "Why not just split the baby?" he asked. "Move it 30 minutes so it would be halfway between the two." Steube thinks his bill could get bipartisan support. The change would make the U.S. out of sync with most of the world — though India has taken a similar approach and in Nepal, the time is 15 minutes ahead of India.

A First for Humanity Confirmed: NASA's DART Mission Slowed the Asteroid's Orbit (sciencenews.org) 54

NASA heralded a new study published Friday documenting a first for humanity — "the first time a human-made object has measurably altered the path of a celestial body around the Sun."

It was 2022's DART mission where NASA crashed a spacecraft into an asteroid — and the experiment "could have implications for protecting Earth from future asteroid strikes," writes ScienceNews: A spacecraft slowed the orbit of a pair of asteroids around the sun by more than 10 micrometers per second... Within a month, researchers showed that the impact shortened Dimorphos' 12-hour orbit by 32 minutes. Some of the rocks knocked off of Dimorphos fled the vicinity completely, escaping the gravitational influence of the Dimorphos-Didymos pair, says planetary defense researcher Rahil Makadia of the University of Illinois Urbana-Champaign. Those rocky runaways took some momentum away from the duo and changed their joint motion around the sun.

To figure out how much that motion was affected, astronomers watched the asteroids pass in front of distant stars, dimming some of the stars' light like a tiny eclipse. These blinks, called stellar occultations, can be visible from anywhere on Earth and are predictable in advance... Calculating how far off occultation timings were from predictions revealed that the asteroids' orbit around the sun was about 150 milliseconds slower than before the DART impact...

Didymos and Dimorphos are not a threat to Earth, Makadia says, and weren't before DART. But knowing how a deliberate impact changes one asteroid's orbit can help make defense plans against another, "in case we need to do a kinetic impact for real."

The researchers spent nearly two and a half years to collect 22 measurements of the asteroid's post-crash position, relying on amateur astronomers "to go out into the middle of nowhere and observe the necessary stellar occultations," acvcording to their paper. Planetary defense researcher even tells ScienceNews "There was an observer who drove two days each way into the Australian outback to get these measurements."

Astronomers Think They've Spotted a Galaxy That's 99.9% Dark Matter (cnn.com) 71

Astronomers have spotted a galaxy they believe is made of 99.9% dark matter, reports CNN — and it's so faint, it's almost invisible: CDG-2, which is about 300 million light-years from Earth, appears to be so rich in dark matter that it could belong to a hypothesized subset of low surface brightness galaxies called "dark galaxies," which are believed to contain few or no stars.... [Post-doctoral astrophysics/statistics fellow Dayi Li at the University of Toronto was lead author on a study about the discovery, and tells CNN] There is no strict definition of dark galaxies... but their existence is predicted by dark matter theories and cosmological simulations. "Where exactly do we draw the line in terms of how many stars they should have is still ambiguous, because not everything in astronomy is as clear-cut as we like," he said. "To be technically correct, CDG-2 is an almost-dark galaxy. But the importance of CDG-2 is that it nudges us much closer to getting to that truly dark regime, while previously we did not think a galaxy this faint could exist."

To observe CDG-2, the researchers used data from three telescopes — Hubble, the European Space Agency's Euclid space observatory and the Subaru Telescope in Hawaii — along with a novel approach that involved looking for objects called globular clusters. "These are very tight, spherical groupings of very olds stars, basically the relics of the first generation of star formation," Li said. Globular clusters are bright even if the surrounding galaxy is not, and previous observations have shown a relationship between them and the presence of dark matter in a galaxy, Li added. Because CDG-2 appears to have very few stars, there must be something else providing the mass that the clusters need to hold themselves together. Li and his colleagues assume that the source of the mass is dark matter.

The researchers found a set of four globular clusters in the Perseus Cluster, a group of thousands of galaxies immersed in a cloud of gas and one of the most massive objects in the universe. Further observations revealed a glow or halo around the globular clusters, suggesting the presence of a galaxy... Astronomers believe, Li explained, that after the formation of the clusters early in the galaxy's existence, larger surrounding galaxies stripped it of the hydrogen gas required to make more individual stars like our sun. "The material that this galaxy needed to continue to form stars was no longer there, so it was left with basically just a dark matter halo and the four globular clusters." The process, he added, would leave behind a skeleton or ghost of "a galaxy that pretty much just failed." As a result of this formation mechanism, the galaxy only has 0.005% of the brightness of our own galaxy, Li said...

Studying potential dark galaxies is important because they provide nearly pristine views of the behavior of dark matter, according to Neal Dalal, a researcher at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Canada, who was not involved with the study.

Robert Minchin, an astronomer at New Mexico's National Radio Astronomy Observatory, told CNN that "it seems likely that other very dark galaxies will be found by this method in the future."

Galileo's Handwritten Notes Discovered in a Medieval Astronomy Text (science.org) 25

In a library in Florence, Italy, historian Ivan Malara noticed handwritten notes on a book printed in the 1500s — and recognized the handwriting as Galileo's. The finding "promises new insights into one of the most famous ideological transitions in the history of science," writes Science magazine — since the book Galileo annotated was a reprint of Ptolemy's second-century work arguing that the earth was the center of the universe. Galileo's notes, perhaps written around 1590, or roughly 2 decades before his groundbreaking telescope observations of the Moon and Jupiter, reveal someone who both revered and critically dissected Ptolemy's work. And they imply, Malara argues, that Galileo ultimately broke with Ptolemy's cosmos because his mastery of the traditional paradigm's reasoning convinced him that a heliocentric [sun-centered] system would better fulfill Ptolemy's own mathematical logic.

Startup Plans April Launch for a Satellite to Reflect Sunlight to Earth at Night (msn.com) 53

A start-up called Reflect Orbital "proposes to use large, mirrored satellites to redirect sunlight to Earth at night," reports the Washington Post, "with plans to bathe solar farms, industrial sites and even entire cities in light that could, if desired, reach the intensity of daylight...."

Slashdot noted their idea in 2022 — but Reflect Orbital now expects to launch its first satellite in April, according to the article. "But its grand vision is largely 'aspirational,' as its young founder, Ben Nowack, told me..." Reflect Orbital's Nowack describes a scene right out of sci-fi: An extremely bright star appears on the northern horizon and makes its way across the sky, illuminating a 5-kilometer circle on Earth, then setting on the southern horizon about five minutes later, just as another such "star" appears in the north. To make the night even brighter, a customer could make 10 "stars" appear at once in the north by ordering them on an app. Two such artificial stars are in development in Reflect Orbital's factory. Nowack showed them to me on a Zoom call. The first to launch is 50 feet across, but he plans later to build them three times that size. If all goes according to plan, he'll have 50,000 of them circling the Earth in 2035 at an altitude of around 400 miles.

Nowack plans to start selling the service "in mostly developing nations or places that don't have streetlights yet." Eventually, he thinks, he can illuminate major cities, turn solar fields and farms into round-the-clock operations for any business or municipality that pays for it. He likened his technology to the invention of crop irrigation thousands of years ago. "I see this as much the same thing," he said, arguing that people would no longer have to "wait for the sun to shine."

The article adds that Elon Musk's SpaceX "wants to launch as many as a million satellites to serve as orbiting data centers — 70 times the number of satellites now in orbit." (America's satellite-regulation Federal Communications Commission grants a "categorical exclusion" from environmental review to satellites on the grounds that their operations "normally do not have significant effects on the human environment.")

The public comment periods for the two proposals close on March 6 and March 9.

ASML Unveils EUV Light Source Advance That Could Yield 50% More Chips By 2030 (reuters.com) 26

An anonymous reader quotes a report from Reuters: Researchers at ASML Holding say they have found a way to boost the power of the light source in a key chip making machine to turn out up to 50% more chips by decade's end, to help retain the Dutch company's edge over emerging U.S. and Chinese rivals. ASML is the world's only maker of commercial extreme ultraviolet lithography (EUV) machines, a critical tool for chipmakers such as TSMC, Intel and others in producing advanced computing chips. "It's not a parlor trick or something like this, where we demonstrate for a very short time that it can work," Michael Purvis, ASML's lead technologist for its EUV source light, said in an interview. "It's a system that can produce 1,000 watts under all the same requirements that you could see at a customer," he added, speaking at the company's California facilities near San Diego. [...]

With the technological advance revealed on Monday, which is being reported here for the first time, ASML aims to outdistance any would-be rivals by improving the most technologically challenging aspect of the machines. This is the quest to generate EUV light with the right power and properties to turn out chips at high volume. The company's researchers have found a way to boost the power of the EUV light source to 1,000 watts from 600 watts now. The chief advantage is that greater power translates into the ability to make more chips every hour, helping to lower the cost of each. Chips are printed similar to a photograph, where the EUV light is shone on a silicon wafer coated with special chemicals called a photoresist. With a more powerful EUV light source, chip factories need shorter exposure times. "We'd like to make sure that our customers can keep on using EUV at a much lower cost," Teun van Gogh, executive vice president for the NXE line of EUV machines at ASML, told Reuters. Van Gogh said customers should be able to process about 330 silicon wafers an hour on each machine by the end of the decade, up from 220 now. Depending on the size of a chip, each wafer can hold anywhere from scores to thousands of the devices.

ASML got the power boost by doubling down on an approach that already places its machines among the most complex inventions of humans. To produce light with a wavelength of 13.5 nanometers, ASML's machine shoots a stream of molten droplets of tin through a chamber, where a massive carbon dioxide laser heats them into plasma. This is a superheated state of matter in which the tin droplets become hotter than the sun and emit EUV light, to be collected by precision optic equipment supplied by Germany's Carl Zeiss AG and fed into the machine to print chips. The key advancements in Monday's disclosure involved doubling the number of tin drops to about 100,000 every second, and shaping them into plasma using two smaller laser bursts, as opposed to today's machines that use a single shaping burst. [...] ASML believes the techniques it used to hit 1,000 watts will unlock continued advances in the future, Purvis said, adding, "We see a reasonably clear path toward 1,500 watts, and no fundamental reason why we couldn't get to 2,000 watts."

T2 Linux Restores XAA In Xorg, Making 2D Graphics Fast Again (t2linux.com) 55

Berlin-based T2 Linux developer René Rebe (long-time Slashdot reader ReneR) is announcing that their Xorg display server has now restored its XAA acceleration architecture, "bringing fixed-function hardware 2D acceleration back to many older graphics cards that upstream left in software-rendered mode." Older fixed-function GPUs now regain smooth window movement, low CPU usage, and proper 24-bit bpp framebuffer support (also restored in T2). Tested hardware includes ATi Mach-64 and Rage-128, SiS, Trident, Cirrus, Matrox (Millennium/G450), Permedia2, Tseng ET6000 and even the Sun Creator/Elite 3D.

The result: vintage and retro systems and classic high-end Unix workstations that are fast and responsive again.

Earth is Warming Faster Than Ever. But Why? (msn.com) 114

"Global temperatures have been rising for decades," reports the Washington Post. "But many scientists say it's now happening faster than ever before." According to a Washington Post analysis, the fastest warming rate on record occurred in the last 30 years. The Post used a dataset from NASA to analyze global average surface temperatures from 1880 to 2025. "We're not continuing on the same path we had before," said Robert Rohde, chief scientist at Berkeley Earth. "Something has changed...." Temperatures over the past decade have increased by close to 0.27 degrees C per decade — about a 42 percent increase...

For decades, a portion of the warming unleashed by greenhouse gas emissions was "masked" by sulfate aerosols. These tiny particles cause heart and lung disease when people inhale polluted air, but they also deflect the sun's rays. Over the entire planet, those aerosols can create a significant cooling effect — scientists estimate that they have canceled out about half a degree Celsius of warming so far. But beginning about two decades ago, countries began cracking down on aerosol pollution, particularly sulfate aerosols. Countries also began shifting from coal and oil to wind and solar power. As a result, global sulfur dioxide emissions have fallen about 40 percent since the mid-2000s; China's emissions have fallen even more. That effect has been compounded in recent years by a new international regulation that slashed sulfur emissions from ships by about 85 percent.

That explains part of why warming has kicked up a bit. But some researchers say that the last few years of record heat can't be explained by aerosols and natural variability alone. In a paper published in the journal Science in late 2024, researchers argued that about 0.2 degrees C of 2023's record heat — or about 13 percent — couldn't be explained by aerosols and other factors. Instead, they found that the planet's low-lying cloud cover had decreased — and because low-lying clouds tend to reflect the sun's rays, that decrease warmed the planet... That shift in cloud cover could also be partly related to aerosols, since clouds tend to form around particles in the atmosphere. But some researchers also say it could be a feedback loop from warming temperatures. If temperatures warm, it can be harder for low-lying clouds to form.

If most of the current record warmth is due to changing amounts of aerosol pollution, the acceleration would stop once aerosol pollutants reach zero — and the planet would return to its previous, slower rate of warming. But if it's due to a cloud feedback loop, the acceleration is likely to continue — and bring with it worsening heat waves, storms and droughts.

"Scientists thought they understood global warming," reads the Post's original headline. "Then the past three years happened."

Just last month Nuuk, Greenland saw temperatures over 20 degrees Fahrenheit above average, their article points out. And "Parts of Australia, meanwhile, have seen temperatures push past 120 degrees Fahrenheit amid a record heat wave..."

This year in America, renewables and battery storage "will account for 99.2% of net new capacity — and even higher if small-scale solar were included," reports Electrek, citing EIA data reviewed by the SUN DAY Campaign: EIA's latest monthly "Electric Power Monthly" report (with data through November 30, 2025), once again confirms that solar is the fastest-growing among the major sources of US electricity... [U]tility-scale solar thermal and photovoltaic expanded by 34.5% while that from small-scale systems rose by 11.3% during the first 11 months of 2025 compared to the same period in 2024. The combination of utility-scale and small-scale solar increased by 28.1% and produced a bit under 9.0% (utility-scale: 6.74%; small-scale: 2.13%) of total US electrical generation for January to November, up from 7.1% a year earlier.

Wind turbines across the US produced 10.1% of US electricity in the first 11 months of 2025 — an increase of 1.2% compared to the same period in 2024. In November alone, wind-generated electricity was 2.0% greater than a year earlier... The mix of all renewables (wind, solar, hydropower, biomass, and geothermal) produced 8.7% more electricity in January-November than a year earlier and accounted for 25.7% of total US electricity production, up from 24.3% 12 months earlier. Renewables' share of electrical generation is now second to only that of natural gas, whose electrical output actually dropped by 3.7% during the first 11 months of 2025...

Since January 1 to November 30, roughly the beginning of the Trump administration, renewable energy capacity, including battery storage, small-scale solar, hydropower, geothermal, and biomass, ballooned by 45,198.1 MW, while all fossil fuels and nuclear power combined declined by 519.2 MW...

[In 2026] natural gas capacity will increase by only 3,960.7 MW, which will be almost completely offset by a decrease of 3,387.0 MW in coal capacity.

Can We Slow Global Warming By Phasing Out Super-Pollutant HFCs? (msn.com) 46

"There's one big bright spot in the fight against climate change that most people never think about," reports the Washington Post. "It could prevent nearly half a degree of global warming this century, a huge margin for a planet that has warmed almost 1.5 degrees Celsius and is struggling to keep that number below 2 degrees..." [M]ore than 170 countries — including the U.S. — have agreed to act on this one solution. That solution: phasing out hydrofluorocarbons (HFCs), a group of gases used in refrigerators, air conditioners and other cooling systems that heat the atmosphere more than almost any other pollutant on Earth. Pound for pound, HFCs are hundreds or even thousands of times better at trapping heat than carbon dioxide.

Companies are replacing HFCs with new gases that trap much less heat. If you buy a new fridge or AC unit in the United States today, it'll probably use one of these new refrigerants — and you're unlikely to notice the difference, according to Francis Dietz, a spokesperson for the Air-Conditioning, Heating and Refrigeration Institute, a trade group representing U.S. HVAC manufacturers... But that invisible transition is one of the most important short-term tactics to keep Earth's climate from going catastrophically off-kilter this century. HFCs are powerful super-pollutants, but the most common ones break down in the atmosphere within about 15 years. That means stopping emissions from HFCs — and other short-lived super-pollutants such as methane — is like pulling an emergency brake on climate change.

"It's really the fastest, easiest and, some would say, the only way to slow the rate of warming between now and 2050," said Kiff Gallagher, executive director of the Global Heat Reduction Initiative, a business that advises companies and cities on cutting greenhouse gas emissions. The only other solution that comes close to the speed and scale of slashing HFCs would be dimming the sun, a much more controversial and potentially dangerous option... [P]hasing out HFCs now "would buy us a little bit of time to develop other solutions that maybe take longer to implement," said Sarah Gleeson, a climate solutions research manager at Project Drawdown, a nonprofit that models how much different strategies would slow climate change. It could also keep the planet from crossing dangerous climate tipping points this century.

'Reverse Solar Panel' Generates Electricity at Night (extremetech.com) 34

Researchers at the University of New South Wales are developing a "reverse solar panel" that generates small amounts of electricity at night by harvesting infrared heat radiated from Earth. "In the past, scientists have demonstrated that a 'thermoradiative diode' can convert infrared radiation directly into electricity; when used to convert heat from Earth, they exploit the temperature difference between Earth and the night sky, generating a current directly from heat," notes ExtremeTech. "This approach completely eliminates the need for heat to generate steam, though the resulting capacity is fairly low." From the report: The researchers estimate they could generate only about a watt per square meter, which isn't much. One reason for the low output is that the Earth's atmosphere lessens the heat differential that drives the generative process; in space, though, that's not an issue.

Now, researchers believe that the ability to generate power in the moments between direct sunlight could help power satellites. That could be especially true in deep space, where periods without sunlight can be longer, and sunlight is often weaker; in these situations, losing electricity to heat loss is unacceptable.

Many satellites already use heat to generate electricity, though with a much more rarified "thermoelectric generator" that uses rare, expensive materials like plutonium to create heat. With thermoradiative diodes, the heat source can be the Sun-warmed body of the satellite itself.

Aurora Watch In Effect As Severe Solar Storm Slams Into Earth (sciencealert.com) 20

alternative_right shares a report from ScienceAlert: Thanks to a giant eruption on the Sun and a large opening in its atmosphere, we're currently experiencing G4 conditions -- a severe geomagnetic storm strong enough to disrupt power grids as energy from space weather disturbances drives electric currents through Earth's magnetic field and the ground. Experts say the storm could even reach G5 levels, the extreme category responsible for the spectacular auroral activity seen in May 2024. In fact, space weather bureaus around the world are forecasting powerful aurora conditions, with some suggesting aurora could be visible at unusually low latitudes, potentially rivaling the reach of 2024's historic superstorm. A livestream of the Northern Lights is available on YouTube. The Aurora forecast is available here.
