New Interstellar Object 3I/ATLAS Could Reveal Secrets of Distant Worlds
Astronomers have confirmed the arrival of 3I/ATLAS, only the third interstellar object ever spotted in our solar system. First seen on July 1, 2025, by the ATLAS survey team in Chile, it was quickly identified by its unusual hyperbolic orbit and comet-like tail. Larger and brighter than either 1I/ʻOumuamua or 2I/Borisov, 3I/ATLAS is estimated to b...

Astronomers Discover 3I/ATLAS, Largest Interstellar Comet Yet Detected
Astronomers have discovered 3I/ATLAS, the third known interstellar comet to pass through our solar system. Detected by the ATLAS telescope in Chile, it’s racing inward at 150,000 mph and will swing closest to the Sun in October. Estimated to be 10–20 kilometers across, it is likely the largest interstellar object observed so far. Signs of comet...
