Scientists Scanned an Interstellar Visitor for Alien Signals and Found Only Earth

Researchers at the SETI Institute examined nearly 74 million radio detections from the interstellar object 3I/ATLAS and found no evidence of technology from beyond Earth. The study, published in The Astronomical Journal, used the Allen Telescope Array in Northern California to conduct one of the most detailed technosignature searches yet aimed at a visitor from…

Webb reveals 16.5 million stars inside the Cigar galaxy

Researchers using NASA’s Webb observations have resolved about 16.5 million individual stars inside Messier 82, a dust-filled galaxy 12 million light-years from Earth. The new survey gives astronomers a sharper view of one of the nearest and most intense stellar nurseries in the local universe. The galaxy, also known as the Cigar galaxy, is forming…
