Telescopes around the world are now tracking a new visitor to our celestial neighborhood. Streaking through at a speed and trajectory that not even the Sun's immense gravity can capture, we will only ...

Alien comet 3I/ATLAS wowed us as it passed through the inner solar system in late 2025, and now JWST has revealed something truly amazing. Based on its unique composition, this interstellar visitor ...

Scientists are looking into the possibility that 'alien spaceship' 3I/ATLAS could have come from within our own solar system. This would challenge the belief that the comet was an "interstellar object ...

One million alien visitors from another star system could already be lurking in the solar system. We aren't talking about "little green men" here, however — more "little (and not so little) gray rocks ...

Despite their (potentially) impressive numbers, these interstellar objects remain extremely difficult to observe. The odds of one venturing within 10 astronomical units—10 times the distance from ...

Object 3I/ATLAS is now too far from Earth to aim a telescope at, but prior observations showed some unusual behavior. The anomalous nature of the object led astrophysicist Avi Loeb to apply a thought ...

Scientists peering at an alien solar system have spotted a pair of planets so different that their traits may be evidence of a massive collision. The key difference is in the planets' density — ...

WHAT are the billions of stars and planets beyond our solar system up to? Do they behave like ours or are we a freak of nature? While definitive answers are far from nailed down, a recent deluge of ...

Alien probes could already be hiding somewhere in our Solar System – and our current surveys are nowhere near good enough to rule them out, according to a NASA‑linked study presented this month by ...

Life may not get blasted off any of the known "super-Earth" worlds as readily as it can from our planet, scientists find. The discovery suggests that any intelligent aliens that develop on such ...
