Astronomers using the James Webb Space Telescope say they may have found a new class of object: a "black hole star," in which a black hole is wrapped in dense gas and radiates in ways that resemble an enormous star. The Guardian reports: The international team made the breakthrough after focusing their attention on a mysterious red spot in images of the early universe captured by Nasa's James Webb space telescope. The object was lurking in the constellation of Cetus, the Whale, billions of light years from Earth. It is thought to have formed 660m years after the big bang, astronomers' leading theory as to how the universe began. Measurements of the exotic body found that while it resembles an immense star, it releases 100bn times more energy than any known star can produce. The energy output is far closer to that observed from black holes than stars. The findings have been published in the journal Nature.

alternative_right shares a report from ScienceDaily: Researchers have found a clever new way to map a part of Earth's upper atmosphere that is notoriously difficult to observe. Using orbital data from roughly 1,200 Starlink satellites, they reconstructed changes in atmospheric density about 500 kilometers above Earth. [...] The resulting density patterns also showed strong consistency with observations from the European Space Agency's SWARM satellites, which measure changes in atmospheric density along their orbital paths. The work expands on an earlier study by the same team. In that research, scientists estimated how thermospheric density changed over time and altitude using general orbital information called Two-Line Element, or TLE, data from Starlink satellites. The new analysis adds another dimension by examining how density varies horizontally across latitude and longitude, revealing more of the thermosphere's geographic structure. The findings could have practical benefits as the number of objects orbiting Earth continues to grow. More accurate information about atmospheric density can improve predictions of satellite motion, helping reduce the chance of collisions between satellites and between satellites and space debris. The technique could also eventually support near-real-time measurements of atmospheric density around satellites. Such monitoring could improve space weather forecasting and contribute to safer, more dependable satellite operations in the future.

An anonymous reader quotes a report from The Guardian: Miniature human organs and other tissues are to be grown from NHS patients' cells in a drive to improve medicine testing and reduce the number of animals used in drug development. Scientists will use the clumps of tissue to learn how diseases vary between patients, helping them identify which treatments are best for different people based on the particular pathology underlying their condition. The move marks a shift away from the traditional use of animals as models for human disease, towards what researchers believe will be more accurate and reliable tests based directly on human tissues. Researchers have been growing tiny clumps of human organs, known as organoids, for more than a decade. Tests show that pieces smaller than a millimeter can mirror key features of full-scale organs and tissues, including how they falter with disease and respond to drugs. Armed with organoids grown from diseased human tissues, scientists can investigate whether new drug candidates reverse pathological changes in all or a subset of patients, and quickly identify ineffective drugs early in the process. Historically, more than 90% of drugs that clear animal testing go on to fail in human trials, raising questions about the value of the tests. US and European medicines regulators now encourage other approaches if available. "It's going to have a major impact on the numbers of animals used and the way we develop new drugs in the future," said Matthias Zilbauer, a clinical professor of paediatric gastroenterology at the Cambridge Stem Cell Institute. "We're not saying there won't be any animal use in the near or foreseeable future, because there are still certain issues that cannot be tested in these new models, but the reduction is very real." "A lot of human diseases either do not occur in animals or occur in a different way because they're not human," added Zilbauer. "We want tests and models that can tell us which treatments work, and in what patients, and a mouse cannot tell us that."

Microsoft has been steadily scaling back its China presence, closing at least 15 branch offices and joint ventures over the past five years as Beijing favors domestic software. U.S. export controls also make it harder to grow its cloud and AI businesses, leaving the market with relatively little economic upside. Reuters reports: Microsoft took a major hit from the erosion of trust between Washington and Beijing, the five people said. China has since 2017 pushed the use of domestic software, which Beijing sees as more secure and whose quality is increasingly competitive with Windows and Office. U.S. restrictions, including export controls on advanced technology, have meanwhile hindered efforts to scale Microsoft's lucrative AI and cloud businesses in China. [...] Microsoft ultimately decided to remain because it had carved out a profitable business servicing Chinese companies like TikTok owner ByteDance, which need Western technology to manage overseas operations, according to three people familiar with the matter. The company also believed that it needed a presence to maintain access to China's world-class engineering talent, two of them said. Microsoft had also cultivated a relationship with the government that is among the deepest of any tech company, its former China head Alain Crozier told Reuters. "Because of the geopolitics ... some days it's a little bit harder, but we never had a crisis," he said. A Microsoft spokesperson did not address questions about the firm's deliberations on its China business but said it operates in a regulatory "environment that applies to every international supplier" and that it remains committed to the Chinese market. The state of Microsoft's China business reflects market competition, regulatory demands and technological trends, the company said.

After 13 years of observations and data processing, astronomers have released the largest two-dimensional map of the universe ever assembled, "offering a sweeping new view of nearly 4 billion celestial objects across roughly three-quarters of the sky," reports Space.com. From the report: The new map, created by the Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys team, contains a staggering 5.6 trillion pixels and combines more than 263,000 telescope exposures collected over more than a decade. The observations span visible and near-infrared wavelengths, providing an enormous portrait of stars, galaxies and other cosmic phenomena across the sky, according to a statement from the National Science Foundation (NSF) NOIRLab. "It's part of the fabric of astronomy research now," David Schlegel, co-lead of the Legacy Surveys and a scientist at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, said in a statement. "When you're working with astronomical objects today, you often start by pulling up the Legacy Imaging Viewer to see what you're looking at."

An anonymous reader quotes a report from The New York Times: Two days before tens of thousands of migrants surged into Ceuta, one of Spain's enclaves on Morocco's northern coast, a newspaper there posted a video on TikTok and Instagram showing two young women walking in the city in wet suits, their hair still damp. The posts didn't say so explicitly, but the implication was clear: The women had just swum across the border from Morocco. "Ceuta can't take it anymore," the newspaper, El Faro de Ceuta, declared in the posts. On the other side of the border, the video resonated very differently. Cropped and reposted in Arabic, the video seemed like an invitation. The women were smiling, flashing peace signs and thumbs up and, most of all, walking around freely. The video seemed to legitimize rumors that had percolated for weeks on social media suggesting that a recent ruling by Spain's Supreme Court meant migrants who arrived illegally by sea could stay in the country. As one account on Facebook put it, falsely, "Ceuta is turning into an open gate," when in fact migrants still faced expulsion after a judicial review. The responses to the posts about the swimmers were a critical part of a cascade of disinformation that experts described as one of the starkest instances in which social media contributed directly to a real-world tragedy.

The Trump administration today unveiled a new program that will allow vetted U.S. companies to conduct cyber surveillance and offensive cyber operations against foreign transnational criminal organizations. A presidential memorandum signed August 12 directs the National Coordination Center to establish and manage the program, expanding the government's fight against cybercrime by tapping the technical capabilities of the private sector. It builds on a March executive order that called for greater private-sector involvement, but goes significantly further by establishing a formal operational framework for the initiative. The White House argues that American companies possess a "critical offensive cyber advantage" whose capabilities have "historically been underutilized" in efforts to identify and disrupt criminal networks operating online. There are two broad categories of authorized activity. "Cyber Surveillance Operations" can involve secretly accessing foreign information systems without authorization to gather intelligence, including information that could later be used for offensive operations. "Cyber Effects Operations," meanwhile, can result in the "manipulation, disruption, denial, degradation, or destruction" of information systems, networks, or infrastructure. It's worth noting that companies will not be free to launch their own operations. The memorandum requires program officials to "review every cyber operations package and provide written approval and direction" before a participating company can act. Operations that could cause death or serious injury, or "rise to the level of use of force or armed attack under international law," are classified as "Critical Outcomes" and cannot be approved through the standard process. The program includes safeguards requiring companies to halt and report operations that unintentionally affect U.S. persons or systems, as well as any imminent threats to critical infrastructure.

Wired reports that consumer neurotechnology is rapidly moving from the lab into workplaces and homes, with companies including Apple, Meta, and Snap developing products that can monitor or interpret brain activity. Researchers warn that as these systems improve, neural data could become the next major privacy battleground. Some neuroscientists are already calling for a series of core rights, coined "neurorights," that protect "mental privacy," "identity," and personal "agency." Here's an excerpt from the article: Over the past two decades, researchers using functional magnetic resonance imaging (fMRI), which tracks the iron in the hemoglobin supplying oxygen to neurons, have been building up increasingly detailed maps and inventories of the mammalian cortex. Thanks to huge advances in machine-learning artificial intelligence -- computer algorithms that are able to sort through enormous amounts of information and use statistical methods to make classifications and predictions -- fMRI scans can now be used to identify everything from depressive thoughts to the nuanced feelings of envy and schadenfreude. Other algorithms have been able to accurately piece together reconstructions of movie clips watched by subjects, just by analyzing their brain scans; or have detected, in probing the brain activity of swing voters in the US presidential election, responding to photographs and videos of presidential candidates, which candidates provoked anxiety or even disgust, and which elicited positive responses or feelings of empathy. In just the last few years, neuroscience researchers have progressed from decoding images and emotions as they play across the cortex to sounds, words, phrases, and even language. In 2023, in a remarkable demonstration of this emerging technology, a woman called Ann Johnson, who had been paralyzed for 18 years by a brain-stem stroke, was able to speak again through the insertion of a grid of 253 electrodes onto the surface of her brain, which translated her neuronal signals into sentences, in real time, at a rate of 78 words per minute (just about half the speed of standard conversation). The research team at the University of California, led by neurosurgeon Edward Chang, had combined this brain-computer interface with an animated avatar of Johnson's head, which spoke in her own voice, as reconstructed from a recording of a 15-minute toast she had given at her wedding. Just as the avatar's mouth spoke Johnson's words as she thought them, so its expressions were similarly influenced by the nuances of her brain activity, which turned her thoughts about facial gestures into displays of emotion -- from smiles to pursed lips and frowns. [...] The more invasive the recording equipment, the richer and more detailed the data. Surgical interventions are at the vanguard of neuroscience and remain very rare -- fewer than 100 people on the planet have brain-computer interfaces like Johnson's embedded beneath their skulls. Yet almost inevitably, a concerted trickle-down effect is occurring. In the summer of 2023, a team at the University of Texas demonstrated that they could use fMRI to translate brain scans into words and sentences, after subjects listened to 16 hours of the storytelling podcasts The Moth Radio Hour and The New York Times' Modern Love to train an AI model. When the subjects then listened to new podcasts, the algorithm was able to convert the gist of what they heard, as it manifested in their brains, into words, phrases, and sentences that roughly captured the stories. As the team's lead computational neuroscientist, Alexander Huth, put it in an interview with Science, "Our thought when we actually had this working was, 'Oh my God, this is kind of terrifying.'" Now noninvasive, wearable brain scanners are beginning to proliferate beyond the lab, making their way into our workplaces and, through the vast global consumer market, into our homes too.

Fei-Fei Li, aka The Godmother of AI, says the biggest AI risk in education may be students losing the motivation and agency to learn, rather than simply using the technology to cheat. She argues against banning AI outright, saying it can be valuable when used to support engaged students instead of replacing the thinking and struggle that learning requires. Techspot reports: Speaking on an episode of the science podcast Huberman Lab this week, Li talked about the fears around how students are using AI. "The absolute bad outcome is that our young generation, their agency and human-level motivation of learning and living is taken away by tools," the ImageNet inventor warned. "It should not be taken away by humans nor should it be taken away by machines." If we see a generation of graduates who have completely relied on AI without actively trying to learn anything for themselves, they risk leaving education without having "properly developed the brain," Li said. [...] Li certainly isn't advocating for a complete ban on students using AI. She believes it can genuinely help struggling students who are already engaged in their learning. Li herself noted how she struggled with organic chemistry as a premed student, when teaching assistants and professors didn't have enough time to answer every question. While there's no obvious solution, Li says we need to find a way to keep children and students' motivation and agency. "Let's find a way to give them the access and the right way of using these tools," she said. Li added that if AI is used properly in education, it could make the students of the future "way smarter than us because they are superpowered."

The CFTC has ordered Kalshi to keep operating in New York, claiming the state's lawsuit against the prediction market created a "market emergency." They said it acted "to ensure market stability" and "ordered the exchange to continue to operate in accordance with the Commodity Exchange Act's Core Principles." Ars Technica reports: The market emergency alleged by the CFTC is that New York Attorney General Letitia James sued Kalshi on July 31. James' lawsuit seeks a court order to permanently enjoin Kalshi "from operating an unlawful gambling business" in the state. The lawsuit also demands that Kalshi "make full restitution to customers who have engaged in betting" and pay financial penalties. "New York intends to make event contract derivatives waste away under its iron curtain of state gaming laws before the courts get the chance to issue final rulings," CFTC Chairman Michael Selig said yesterday. "Congress did not intend for derivatives exchanges to be regulated under a patchwork of state gaming laws... New York has no business regulating these interstate financial markets. The commission is required by law to ensure order in these markets, and that is what we have done today." [...] The CFTC says it alone has the power to regulate platforms such as Kalshi and Polymarket under the Commodity Exchange Act, a US law that gives the CFTC exclusive jurisdiction over designated contract markets (DCMs). "These are financial exchanges that offer financial instruments and operate across state lines," Selig said yesterday. "They match the bid from a resident of one state with the offer of a resident from another state and submit the trade to a clearinghouse that backstops the transactions of customers throughout the country."

Researchers at Israeli cybersecurity firm Dream say suspected China-linked hackers used an open-source AI-agent system to conduct what may be the first observed end-to-end autonomous cyberattack against a government. According to the Financial Times (paywalled), the attack compromised at least 85 accounts and resulted in the theft of more than 2,500 personnel records from Taiwanese systems. Tom's Hardware reports: The campaign reportedly ran for four days at the beginning of July and at times deployed as many as eight autonomous agents in parallel. Dream said the system mapped 21 government systems before compromising user accounts and extracting personnel information. The attackers subsequently expanded their activity to Taiwan's nuclear safety agency, at least seven energy companies, government suppliers, and other government systems. Dream says it found the evidence inside a 160-megabyte (160MB) online archive that surfaced during its broader tracking of cyberthreat actors. The archive reportedly held 1,395 files showing that the tool was built on two open-source AI agent systems -- Hermes and OpenClaw -- both of which can be downloaded freely and are designed to let large language models carry out multi-step tasks on their own. Researchers could not determine which underlying model powered the agents, but the data reportedly showed the model's safeguards had been sidestepped by presenting the intrusion as an authorized penetration test rather than a real attack. Of particular concern is that the toolkit for the hack comprised such easily available systems, neither of which was purpose-built for offense. The operators appear to have assembled a capable autonomous tool out of components any developer can pull down and run. What the researchers describe as the tool's most striking feature was its ability to continuously devise attacks on its own, rather than follow a preprogrammed route. The platform continuously assessed available evidence, ranked possible attack paths, and reprioritized them as circumstances changed. When one technique failed, the tool tasked another agent with searching the internet for information and developing an alternative approach.

An anonymous reader quotes a report from Ars Technica: On Monday, passengers aboard Delta flight 591 going from Las Vegas to Atlanta allegedly spoofed the onboard Wi-Fi, raising the attention of federal law enforcement. The incident came one day after the DEF CON security conference concluded in Las Vegas, and was first described on social media accounts that follow publicly available air-to-ground messages, known as ACARS. According to the "ACARS Drama" account, a message was sent by pilots from the plane stated: "NO INFO AS OF NOW WE HAVE A BUNCH OF PAX THAT WERE AT A CYBER CONFERENCE IN LAS THEY WERE ABLE TO JAM OUR WIFI AND BROADCAST THEIR SIGNAL." A description of the incident posted to Reddit further stated that these passengers created a fake hotspot ("Delta WiFi Fast"), with a phishing landing page "designed to harvest passengers' personal credentials." This technique, sometimes known as an "evil twin" attack, has been long-known to the IT security community. It involves setting up a fake Wi-Fi network and then capturing login credentials and other data. "One initial finding is an unauthorized WiFi network, which was not provided, operated, or supplied by Delta, was present onboard the aircraft for a short time during the flight," said a Delta spokesperson. Delta further noted that the flight's safety was "never in question and no aircraft operating systems were affected," and that no emergency was declared. Ars notes that the "actual onboard Wi-Fi was disabled for 30 minutes."

Google has unveiled the $29 Pixel Tag, its long-awaited AirTag rival that combines UWB with Bluetooth 6.0 Channel Sounding for two forms of precision tracking. It launches November 11. The Verge reports: The Pixel Tag is a slim oblong device available in one grayish color -- Fog -- that weighs about 12g, or 0.4oz. Like the AirTag, it has no built-in hooks or clips for attaching to objects you want to track. There's a single button that will trigger a sound on your phone, for the rare occasion when you've got the Tag but have lost your main device. It also has an IP67 rating, so it should be safe from dust and rain. As for the battery, the Pixel Tag takes CR2032 coin batteries, and says one battery should last for over a year. Naturally, it'll be compatible with Google's Find Hub network, which leverages the Bluetooth capabilities of Android devices worldwide to help locate lost objects. [...] Once you're close enough to the Pixel Tag, UWB lets the Find Hub app display the distance and direction to the tracker, so long as you're using a phone with a UWB chip. Channel Sounding is a newer development that can display the exact distance, but not direction, and it will work with any phone or tablet that includes Bluetooth 6.0. The Moto Tag 2 is the only other tracker to currently support it.

A German digital-rights group has filed a criminal complaint against Meta, Ray-Ban parent EssilorLuxottica, and several retailers over Meta's AI smart glasses, arguing the devices can enable covert recording in violation of German privacy law. Prosecutors have begun a preliminary review, while Germany's network regulator says smart glasses are legal "as long as the recording function is clearly visible." Reuters reports: "There's no place to escape from smart glasses. You have to expect at any moment to be filmed and then exposed on the internet," said HateAid managing director Josephine Ballon. The organization reported the management of Meta, units of spectacles maker EssilorLuxottica including Ray-Ban, as well as retailers Fielmann, Apollo-Optik, Mister Spex and MediaMarkt to the Frankfurt-based digital crime prosecution unit ZIT. HateAid said its complaint was based on a federal digital data protection law that prohibits the sale of communication devices designed to film people without them noticing. ZIT confirmed it received a complaint from HateAid invoking that law, saying it would routinely investigate on a preliminary basis whether there are grounds for a deeper probe. MediaMarktSaturn Retail Group said it was taking the complaint very seriously, adding that its suppliers had contractual obligations for all goods to be compliant with the law. Mister Spex said it had not been officially notified of a complaint and that it was taking protection of privacy very seriously.

At its Made by Google 2026 event today, Google unveiled a slew of new devices, headlined by the Pixel 11, Pixel 11 Pro, and Pixel 11 Pro Fold. Here's a breakdown of the company's latest smartphones, provided by TechCrunch: Pixel 11: The standard Pixel 11 gets a redesigned camera bar that is thinner than the one on the previous generation. Google says the new camera bar is more than 40% thinner and now uses an all-glass surface that stretches across the width of the phone. Google is also increasing the base storage to 256GB, doubling the previous starting capacity. The starting price for the new model is set at $899, reflecting a $100 increase compared to the Pixel 10. This price hike comes with the decision to drop the 128GB storage option. Plus, the ongoing RAM supply shortage plays a part in this increase. Pixel 11 Pro and Pro XL: Google is making durability a bigger part of the Pro lineup. The company says the Pixel 11 Pro and Pixel 11 Pro XL have improved drop resistance and a new anti-scratch display coating that provides more than twice the scratch resistance of the Pixel 10 Pro models. The Pixel 11 Pro starts at $1,099, compared to $999 for the Pixel 10 Pro. Pixel 11 Pro Fold: Google says the new foldable is nearly 10% lighter and almost 1mm thinner than the Pixel 10 Pro Fold. It also has slimmer bezels, a 48-megapixel main camera, and 30x Super Zoom. The company is also building on the IP68 water and dust resistance introduced with the Pixel 10 Pro Fold. The Pixel 11 Pro Fold uses a glass-fiber composite back cover designed to better withstand cracking, while a redesigned hinge offers additional protection for the inner display. Google says the changes make the model three times more durable than its predecessor. There were also several new Gemini-powered features unveiled at the event. Google is expanding "Live Transcribe" to support American Sign Language, using the Pixel Camera to translate signing into text in real time. A new voice-input feature called "Rambler" is designed to understand natural, unstructured speech, including filler words and run-on sentences. Google is also integrating "Circle to Search" more directly into the Pixel Camera for identifying objects, translating text, and asking questions about what users see.

The FAA says its push to recruit video gamers as air traffic controllers has helped it hire more than 2,000 trainees, reaching 94% of its hiring goal. Another 2,000-plus candidates are in the pipeline. CBS News reports: U.S. Secretary of Transportation Sean Duffy said in a recent social media post that the federal agency's recruitment campaign to recruit gamers as air traffic controllers has been a "game changer" for the Federal Aviation Administration. [...] When Duffy announced the initiative in April, he acknowledged that the Transportation Department needed to extend its reach to recruit prospective air traffic controllers. "A lot of what they do playing games ... is what they do ... controlling traffic in the air," Duffy told CBS News senior transportation correspondent Kris Van Cleave in an interview on Tuesday at New Jersey's Newark Liberty International Airport. Duffy added that many current trainees started out as gamers. Only about 25% of controllers hold a traditional college degree, while former controllers note that gaming requires many of the same skills that air traffic controllers use on the job, such as thinking quickly, staying focused and managing multiple sources of information as they guide more than 80,000 flights to their destinations daily.

alternative_right shares a report from Phys.org: Scientists from the Czech Republic have created microscopic cleanup robots that successfully removed microplastics from both soil and aquatic environments in the lab. Details of their work are published in the journal npg Asia Materials. To build the robots, researchers started with microscopic MXene particles made of ultrathin, stacked layers. The material has a large surface area and surface chemistry that help it attract and hold plastic. They then coated the particles with magnetic nickel nanoparticles so rotating magnetic fields could drive the tiny robots. Then came the testing phase. The team placed swarms of these microbots into water and soil samples contaminated with plastic. The externally generated magnetic fields made the robots spin and tumble through the liquid and squeeze through tiny water-filled gaps in the soil. "In soil environments, the microrobots can navigate through water-permeated soil microenvironments, actively disrupt microplastic entrapment within soil matrices, and extract them," the study authors commented in their paper. As they moved, their sticky surfaces collided with microplastics, binding to them and dragging them along. The researchers then used a magnet to pull the microrobots, along with their trapped plastic cargo, out of the samples. They performed well. In water, they removed about 94% of test polystyrene particles and 89% of PET (polyethylene terephthalate) in around an hour. In the model soil, they removed about 81% of the polystyrene and 72% of PET. This outperformed the same MXene material used without magnetic motion, which relied on passive adsorption rather than actively moving through soil and water.

sciencehabit shares a report from Science Magazine: For more than half a century, physicists have searched for one of the strangest particles predicted by modern theory. It would be made almost entirely of gluons, the elusive subatomic particles that carry the strong nuclear force. Now, using a particle collider in Beijing, researchers say they have effectively proved the existence of such a "glueball." In a preprint posted last month on arXiv and in a presentation last week at the International Conference on High Energy Physics (ICHEP), the researchers argue that a particle called X(2370), which they produced by smashing electrons into positrons at high energies, has the properties expected of a glueball. "It's an experimental triumph," says Colin Morningstar, a particle physicist at Carnegie Mellon University who was not involved in the finding. "It's the strongest evidence yet that particles dominated by a glueball component can exist in nature."

A South Korean lunar orbiter has captured the first before-and-after images of the Moon's crash scene caused by a stray SpaceX Falcon 9 rocket. The Associated Press reports: The Korea Aerospace Research Institute's Danuri spacecraft flew over the impact site soon after the Falcon 9 upper stage inadvertently plowed into the moon on Wednesday. Danuri made multiple passes, snapping photos from lunar orbit that were released by the space agency Thursday. The terrain is noticeably darker where the rocket hit and carved out a crater, sending dust and rock everywhere. Korean space officials said Danuri gathered before and after shots. NASA expects its Lunar Reconnaissance Orbiter to fly over the crash site next week to view the aftermath. You can view the images here.

NASA has squeezed at least another year of science out of Voyager 2 by cutting power to nonessential systems and switching to lower-power alternatives. Voyager 1 is expected to receive the same power-saving changes in the coming months. Space.com reports: Voyager 2 and its twin launched in 1977, called Voyager 1, rely on a form of nuclear battery known as a radioisotope thermoelectric generator that uses the heat produced by the decay of plutonium. But the supply of plutonium on each probe drops at about four watts a year on each spacecraft. To keep the probe running on this dwindling power supply, engineers recently reduced Voyager 2's power requirements by turning off a few non-science devices and using "lower-power alternatives" that are still effective enough to keep the spacecraft warm while it's so far from the sun, NASA officials said in a statement. "The spacecraft power margins have grown razor thin, requiring the team to conserve energy by shutting off non-essential devices and systems," NASA officials wrote of the mission, which is managed by the agency's Jet Propulsion Laboratory. The drop in power is having a measurable science impact on both spacecraft -- each has turned off two of their science instruments since 2024 alone. While some of these instruments were shut off after the spacecraft finished their historic planetary flybys decades ago, others were turned off due to power requirements. Each spacecraft initially launched with 10 instruments, and Voyager 2 is now down to only three instruments. At first it looked as though Voyager 2 would have to shut down another of these instruments later this year, but luckily, the new power shifts will allow all three to operate "for at least another year," NASA said.
