3I/ATLAS is only the third interstellar object ever detected. It poses no threat to Earth. The comet is currently dim, requiring a telescope to see. It will be closest to the sun in late October.

CAPE CANAVERAL, Fla. — NASA has discovered an interstellar comet that’s wandered into our backyard. The space agency spotted the quick-moving object with the Atlas telescope in Chile recently, and ...

A rare visitor from another star system has been spotted. It's the interstellar comet 3I/ATLAS, and it was detected on July 1 by the NASA-funded Asteroid Terrestrial-impact Last Alert System, or ATLAS ...

Astronomers observing the interstellar object 3I/ATLAS have detected a faint, teardrop-shaped tail stretching behind it—aligned directly opposite the Sun. The discovery, detailed by physicist Avi Loeb ...

Current estimates suggest 3I/ATLAS may be up to 12 miles in diameter. According to physicist Marshall Eubanks, the object appears to be arriving from the thin galactic disk, the plane in which most ...

Interstellar objects like 3I/ATLAS that have been captured in planet-forming disks around young stars could become the seeds of giant planets, bypassing a hurdle that theoretical models have ...

Astronomers recently discovered a rare interstellar object passing through our solar system, and a Harvard physicist is sounding the alarm that its strange characteristics might indicate it’s more ...
