WASHINGTON (Reuters) -NASA released fresh images on Wednesday of the interstellar object called 3I/ATLAS that astronomers have determined is a comet probably even older than our solar system, as U.S.

We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a new study suggests.

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 ...

Space scientists have revealed a new image of the mysterious space rock that passed through our solar system. Researchers said the picture shows the interstellar Comet 3I/ATLAS, suggested to be a ...

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.
