Astronomers find 5 potential alien structures harvesting energy from the stars

Scientists have identified five potential Dyson spheres—massive alien megastructures that could harvest energy from stars—using powerful infrared telescopes like the James Webb Space Telescope. Project Hephaistos examined 5 million stars and initially found seven candidates around red dwarf stars, which would appear as unusual infrared emissions rather than visible light. This discovery provides new methods for detecting advanced extraterrestrial civilizations through their potential technosignatures.
