NASA's Webb telescope rules out two new Dyson sphere candidates
The latest Swedish-led search for technosignatures in the form of Dyson spheres has again come up empty-handed. The two latest stellar candidates in the hunt for such hypothetical extraterrestrial technology have been eliminated as Dyson spheres.
Recent searches for Dyson spheres, hypothetical megastructures built around stars to harness energy, have yielded no evidence so far. Two new candidates identified by Project Hephaistos using NASA's James Webb Space Telescope turned out to be false alarms. The infrared excesses previously thought to be from these structures were actually caused by background galaxies, not extraterrestrial technology.
