The James Webb Space Telescope and other international observatories have spotted a 13-billion-year-old supernova. On Tuesday, the European Space Agency (ESA) announced the sighting of a gamma-ray burst from a star that exploded when the Universe was only 730 million years old. The Webb telescope even detected the supernova's host galaxy. Before this observation, the oldest recorded supernova was from when the Universe was 1.8 billion years old. That's a difference of more than a billion years.You can see the gamma-ray burst in the image below.

Levan (IMAPP)"This observation also demonstrates that we can use Webb to find individual stars when the Universe was only 5 percent of its current age," co-author Andrew Levan wrote in the ESA's press release. "There are only a handful of gamma-ray bursts in the last 50 years that have been detected in the first billion years of the Universe. This particular event is very rare and very exciting."Researchers learned that the 13-billion-year-old explosion shared many traits with modern, nearby supernovae. While that may not sound shocking, scientists expected a more profound difference. That's because early stars likely had fewer heavy elements, were more massive and didn't live as long. "We went in with open minds," co-author Nial Tanvir said. "And lo and behold, Webb showed that this supernova looks exactly like modern supernovae."Detection was an international relay race. First, NASA's Neil Gehrels Swift Observatory noted the X-ray source's location. (That helped Webb to make subsequent observations that determined its distance). Then, the Nordic Optical Telescope on the Canary Islands in Spain made observations indicating that the gamma ray might be very distant. Hours later, the European Southern Observatory's Very Large Telescope in Chile estimated its age: 730 million years after the Big Bang. All of this happened in under 17 hours, according to the ESA.The team behind the observation has been approved to spend more time with Webb studying gamma-ray bursts from the early Universe and the galaxies behind them. "That glow will help Webb see more and give us a 'fingerprint' of the galaxy," Levan predicted.This article originally appeared on Engadget at https://www.engadget.com/science/space/the-webb-telescope-spots-a-supernova-from-13-billion-years-ago-194327489.html?src=rss

Owners of the Porsche Macan and upcoming Porsche Cayenne Electric will be able to unlock and start their cars with their Galaxy phones, Samsung has announced. The cars, alongside other Porsche models, are gaining support for Samsung Wallet's Digital Key feature, which lets users wirelessly control their car over a secure UWB or NFC connection.Digital Key support will be available in Europe in December, before rolling out globally, "aligned with the launch timeline of Porsche vehicles," Samsung says. Samsung Wallet is available on Samsung devices as old as the Galaxy S20, Note 20, Galaxy Z Fold 2 and Galaxy Flip 5G, and is included on the majority of the company's new phones. Like similar features on Google's Pixels and Apple's iPhones, Digital Key allows Porsche owners with a supported Galaxy phone to unlock, lock and start their car directly from their phone. If your phone is ever taken, you can also remotely lock or delete a Digital Key to keep your car safe.Samsung added Digital Key support to select Volvo and Polestar EVs in February 2025. The feature first became available in 2021, and is one of several ways the phone maker imagines people will use Samsung Wallet. Beyond digital car keys, the app can also store credit and debit cards and be used to transfer money with a tap.This article originally appeared on Engadget at https://www.engadget.com/mobile/smartphones/samsung-wallet-to-gain-support-for-digital-porsche-keys-193000085.html?src=rss

Sony's 2025 PlayStation Wrap-Up is now available. The recap, which is similar to those from music streaming services, sums up gaming habits from throughout the year. It shows players how many hours they used their PS4 or PS5, what games they played the most, preferred genres, trophy counts and more. These digital cards are shareable on social media, which is kind of the whole point. Nothing says "bragging rights" more than offering definitive proof of how long you spent on a couch grinding in Clair Obscur: Expedition 33 or wandering the wasteland in Death Stranding 2. Sony This year, the recap provides insight into how much players interacted with accessories like the PlayStation Portal and PS VR2. It also details the "most used DualSense wireless controller design." The 2025 Wrap-Up will be available until January 8. Once completed, players also get a "unique glass-themed avatar." It's only available for adults. My PlayStation wrap up 2025 pic.twitter.com/9Em96T4Xce priceless (@Real__Priceless) December 9, 2025 The PlayStation Wrap-Up has been around since 2017, though it ran into some issues with accessibility in 2024. Spotify introduced the basic idea with Wrapped back in 2015. Since then, the concept of a shareable year-end streaming list has spread like a virus. Just about everyone does it now, from Apple Music to Nintendo and even YouTube. We love to reflect on things we recently experienced, don't we folks?This article originally appeared on Engadget at https://www.engadget.com/gaming/playstation/playstations-2025-wrap-up-is-here-so-you-can-see-how-many-hours-youve-sunk-into-death-stranding-2-191508693.html?src=rss
