The interstellar visitor, only the third such object to be discovered passing through our solar system, ignited controversial ...

Harvard astrophysicist Avi Loeb claims humanity missed a historic chance to find alien life on interstellar object 3I/ATLAS, warning it may have been a spacecraft on a seeding mission.

The NASA/ESA Hubble Space Telescope reobserved interstellar comet 3I/ATLAS on 30 November with its Wide Field Camera 3 instrument. At the time, the comet was about 286 million kilometers from Earth.

(KTLA) — NASA on Wednesday released new images and data of Comet 3I/ATLAS, the rare interstellar object that set off weeks of speculation — and a full-blown online debate — over whether it could be an ...

Scientists confirmed that the interstellar comet 3I/ATLAS, which passed closest to Earth in December 2025, showed no detectable technosignatures strong enough to suggest it is an alien spacecraft.
