At any given time across the universe, massive cosmic bodies are releasing incomprehensible amounts of energy. Stars burn like celestial nuclear fusion reactors, quasars emit thousands of times the luminosity of the Milky Way galaxy, and asteroids slam into planets. But all of these pale in comparison to a new class of events discovered by researchers at the University of Hawai’i’s Institute for Astronomy (IfA). According to their findings published June 4 in the journal Science Advances, it’s time to classify the universe’s most energetic explosions as extreme nuclear transients–or ENTs. ENTs are as devastating as they are rare. They only occur when a massive star at least three times heavier than the sun drifts too close to a supermassive black hole. The colliding forces subsequently obliterate the star, sending out plumes of energy across huge swaths of space. Similar events known as tidal disruption events (TDEs) are known to occur on a (comparatively) smaller scale, and have been documented for over a decade. But ENTs are something else entirely. “ENTs are different beasts,” study lead author and astronomer Jason Hinkle explained in an accompanying statement. “Not only are ENTs far brighter than normal tidal disruption events, but they remain luminous for years, far surpassing the energy output of even the brightest known supernova explosions.” Hinkle was first tipped off to ENTs while looking into transients—longlasting flares that spew energy from a galaxy’s center. Two particularly strange examples captured by the European Space Agency’s Gaia mission caught his eye. The pair of events brightened over a much longer timeframe than previously documented transients, but lacked some of their usual characteristics. “Gaia doesn’t tell you what a transient is, just that something changed in brightness,” Hinkle said. “But when I saw these smooth, long-lived flares from the centers of distant galaxies, I knew we were looking at something unusual.” Hinkle soon reached out to observatory teams around the world for what would become a multiyear project to understand these anomalies. In the process, a third suspect was detected by the Zwicky Transient Facility at the Palomar Observatory in San Diego. After months of analysis, Hinkle and collaborators realized they were witnessing something unprecedented. An infrared echo tells us that a dusty torus surrounds the central black hole and newly-formed accretion disk. Credit: University of Hawai’i The ENTs analyzed by astronomers displayed smoother, longer lasting flares that pointed towards something very particular—a supermassive black hole accreting a giant, wayward star. This contrasts with a more standard black hole that typically acquires its material and energy unpredictably, resulting in irregular brightness fluctuations. The energy and luminosity of an ENT boggles the mind. The most powerful ENT documented in Hinkle’s study, Gaia18cdj, generated 25 times more energy than the most powerful known supernovae. For reference, a standard supernova puts out as much energy in a single year as the sun does across its entire 10 billion year lifespan. Gaia18cdj, meanwhile, manages to give off 100 suns’ worth of energy over just 12 months. The implications of ENTs and their massive energy surges go far beyond their impressive energy outputs. Astronomers believe they contribute to some of the most pivotal events in the cosmos. “These ENTs don’t just mark the dramatic end of a massive star’s life. They illuminate the processes responsible for growing the largest black holes in the universe,” said Hinkle. From here on Earth, ENTs can also help researchers as they continue studying massive, distant black holes. “Because they’re so bright, we can see them across vast cosmic distances—and in astronomy, looking far away means looking back in time,” explained study co-author and astronomer Benjamin Shappee. “By observing these prolonged flares, we gain insights into black hole growth when the universe was half its current age… forming stars and feeding their supermassive black holes 10 times more vigorously than they do today.” There’s a catch for astronomers, however. While supernovae are relatively well-documented, ENTs are estimated to occur at least 10 million times less often. This means that further study requires consistent monitoring of the cosmos backed by the support of international governments, astronomical associations, and the public.

If you’re in the homebuying market, you’ve probably come to realize that the grass is always greener in the listing description—both literally and figuratively. Real estate agents sometimes get creative with Photoshop edits on listing photos, often brightening up the grass and editing out unsightly objects, like a neighbor’s clunker car or wires cluttering a bedroom. They also use some descriptive language that can be, well, deceptive. Adjectives like cozy and charming may evoke good feelings in potential buyers, but they’re high on the list of frequently used adjectives that probably don’t mean what you think they do. Photos and descriptions give you a teaser, but nothing beats an in-person tour for catching any potential sneaky details. Still, there are certain phrases to keep an eye out for as you're browsing for your next dream home online. Below, we're rounding up 10 common words or phrases often found in real estate listings should raise red flags, according to real estate pros. Related Stories“Charming”DreamPictures//Getty ImagesOr, similarly, unique. “Often, this means the property has some quirks that might not appeal to everyone,” real estate expert Yawar Charlie, director of the luxury estates division at Aaron Kirman Group, says. “It could be anything from a funky floor plan to unconventional finishes.” Think about resale value and whether any of these quirks might be a dealbreaker for future buyers, should you choose to sell“Cozy”Cozy is most likely a code word for lacking square footage, Charlie says. “When they call it cozy, they’re hinting that it might be a bit cramped,” he says. “Check for square footage and layout specifics.”“Home Being Sold As Is”"As is" is perhaps one of the biggest red flags in real estate. “It often signals that the property may have significant issues the seller is trying to offload,” says Nikki Bernstein, a global real estate advisor with Engel & Völkers Scottsdale.According to Bernstein, an "as is" condition indicates that the seller is likely emotionally detached and unwilling to negotiate on price or concessions. It also suggests they may be withholding information, indicating there could be hidden problems waiting to be uncovered during inspection, she says. “As is might as well be a warning: ‘Buyer beware,’” Bernstein says. “Fixer Upper”Mableen//Getty ImagesIf you’ve got a design-build background or are looking for homes that are worth renovating, a property advertised as a fixer-upper might make for a fun challenge. But this phrase usually means the property has seen better days and needs some TLC, which is not what most buyers are looking for. Charlie's advice? Bring a contractor or a handyman to the home inspection with you. “You’re not just checking for cosmetic issues; you want to get the lowdown on structural problems, electrical updates, and plumbing repairs,” Charlie says. “A fixer-upper can quickly turn into a money pit.”If you choose to pursue a home that needs a fair amount of love, make sure you’ve got the right loan, Virginia Realtor and real estate broker Michelle Brown cautions. For example, a FHA 203K loan lets buyers roll home improvement costs into their mortgage.“Investors’ Dream”This phrase typically signals the property is in poor condition but priced low for potential profit through renovations or redevelopment, Brown says. This is another instance where you’ll want to have a contractor with you to get a full picture of all the repairs that may be needed.“Make This Home Your Own”This phrase signals the home is likely outdated and in need of cosmetic updates at the very least, New Jersey Realtor Larry Devardo says. Listings that advertise “potential” or say “home has endless possibilities” are also indicators that repairs and updates are needed, he says. “Great Bones”DreamPictures//Getty ImagesOn the upside, “great bones” means the home is structurally sound with strong infrastructure, Maryland Realtor Ellie Hitt says. On the downside, it likely needs a lot of cosmetic updates to bring it up to date with modern conveniences and aesthetics.“Needs TLC”Often, when a home requires cosmetic work, “TLC” is noted, indicating the property needs someone who is willing to put in a little bit of elbow grease, agent Karen Kostiw of Coldwell Banker Warburg says. You may be thinking of new carpet, updated cabinets, and a few other touch-ups, but in some cases, TLC could actually mean the property requires a gut renovation.“Motivated Seller”Translation: The seller is eager to sell, possibly due to financial issues, a pending foreclosure, or a property that has been on the market for a while, says Jeffrey Borham, owner of Tampa Bay, Florida Team Borham. “This could be an opportunity for negotiation,” he adds. “However, investigate why the seller is motivated; there could be hidden issues that have deterred other buyers.”Similarly, “priced to sell” could mean a whole host of things, ranging from the property needs some work or the seller wants to start a bidding war, New York City Broker Sean Adu-Gyamfi of Coldwell Banker Warburg says.“Hot Listing”Some agents advertise “hot listings” on the MLS to create urgency, even if there are no other offers, Misty Spittler, a licensed public insurance adjuster and certified roof inspector, says. Don’t feel pressured, though. She recently had a client bid $20,000 over asking on a listing advertised as hot. Spittler’s inspection found $30,000 of necessary repairs, so the client was able to renegotiate.Follow House Beautiful on Instagram and TikTok.

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. What’s next for AI and math The modern world is built on mathematics. Math lets us model complex systems such as the way air flows around an aircraft, the way financial markets fluctuate, and the way blood flows through the heart. Mathematicians have used computers for decades, but the new vision is that AI might help them crack problems that were previously uncrackable.   However, there’s a huge difference between AI that can solve the kinds of problems set in high school—math that the latest generation of models has already mastered—and AI that could (in theory) solve the kinds of problems that professional mathematicians spend careers chipping away at. Here are three ways to understand that gulf.  —Will Douglas HeavenThis story is from our What’s Next series, which looks across industries, trends, and technologies to give you a first look at the future. You can read the rest of them here. Inside the effort to tally AI’s energy appetite —James O’Donnell After working on it for months, my colleague Casey Crownhart and I finally saw our story on AI’s energy and emissions burden go live last week.  The initial goal sounded simple: Calculate how much energy is used when we interact with a chatbot, then tally that up to understand why leaders in tech and politics are so keen to harness unprecedented levels of electricity to power AI and reshape our energy grids in the process.It was, of course, not so simple. After speaking with dozens of researchers, we realized that the common understanding of AI’s energy appetite is full of holes. I encourage you to read the full story, which has some incredible graphics to help you understand this topic. But here are three takeaways I have after the project.

The technology has the potential to produce the material, which is used in vehicles and defense applications, with net-zero greenhouse-gas emissions. Why it matters: Today, China dominates production of magnesium, and the most common method generates a lot of the emissions that cause climate change. If Magrathea can scale up its process, it could help provide an alternative source of the metal and clean up industries that rely on it, including automotive manufacturing. Read the full story. —Casey Crownhart A new sodium metal fuel cell could help clean up transportation A new type of fuel cell that runs on sodium metal could one day help clean up sectors where it’s difficult to replace fossil fuels, like rail, regional aviation, and short-distance shipping. The device represents a departure from technologies like lithium-based batteries and is more similar conceptually to hydrogen fuel cell systems. The sodium-air fuel cell has a higher energy density than lithium-ion batteries and doesn’t require the super-cold temperatures or high pressures that hydrogen does, making it potentially more practical for transport.
