A mysterious spider-like structure lurking on Jupiter’s fourth largest moon Europa may finally have a good explanation, nearly 30 years after its discovery. The arachnid impostor has also been given a devilish new name.In March 1998, NASA’s Galileo spacecraft (which studied Jupiter and its major moons from 1995 to 2003) approached the frozen ocean moon Europa, considered one of the most likely locations in the solar system for extraterrestrial life. During the flight, the spacecraft mapped a 22-kilometre-wide impact structure called Manannan Crater on the moon’s icy surface, and discovered that something strange was lurking inside.Hidden in a deep hole…
British metal detectors have unearthed an impressive collection of Anglo-Saxon gold and garnet pendants that may have been buried underground after being ritually ‘killed’ 1,400 years ago.In the spring of 2023, two detectorists discovered a collection of four gold pendants and a gold brooch on a hillside in the village of Donnington-on-Bain, about 125 miles (200 km) north of London. Detectors reported the find under the UK Portable Antiquities Scheme, and archaeologist Lisa Brundle, excavations liaison officer for the county of Lincolnshire, studied the extraordinary gem.”This pendant is unusual for a complete necklace set,” Brundle wrote in a study published…
Another day, another nuclear startup scores another nine-figure round. Radiant Nuclear announced today that it has raised more than $300 million, just one day after Last Energy announced it had raised $100 million. Three weeks ago, X-energy raised $700 million, and in August, Aalo Atomics raised $100 million. Heck, Radiant itself raised $165 million just six months ago. Given the series of investments, it seems natural to wonder whether the nuclear world is in a bubble. Investment in this technology has gone hand in hand with the data center boom. AI requires vast amounts of electricity, and tech companies and…
Google today aims to steal OpenAI’s thunder with the release of its faster and cheaper Gemini 3 Flash model, which is based on Gemini 3 released last month. The company has also made this the default model for the Gemini app and AI mode in search. The new Flash model comes six months after Google announced the Gemini 2.5 Flash model, and it comes with significant improvements. In benchmarks, the Gemini 3 Flash model significantly outperforms its predecessor and in some respects matches the performance of other Frontier models such as the Gemini 3 Pro and GPT 5.2. For example,…
Saturn’s largest moon, Titan, may harbor a habitable world covered in slimy sea ice, new research suggests.Back in 2008, NASA’s Cassini spacecraft collected data on Titan that suggested there may be an open ocean beneath the moon’s frozen crust. But researchers say new analysis suggests that what lies beneath is more “muddy tunnels and pockets of snowmelt.”The results, published Wednesday (December 17) in the journal Nature, have major implications for understanding how common water is in the rest of the world. Water is a critical element for life, so if confirmed, this study could have implications for the search for…
