Remember 3I/ATLAS? Yes, the interstellar comet that made plenty of headlines in 2025 is still romping through our solar ...

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 ...

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 ...

There may be 19 asteroids in orbit around the sun that come from somewhere else entirely. If true, we could visit an alien 'world' without ever leaving the confines of the solar system. Share on ...

For millions of years, a frozen wanderer drifted between the stars before slipping into our solar system as 3I/ATLAS—only the third known interstellar comet ever spotted. When scientists turned NASA’s ...

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 ...

At 150 light-years from Earth, the Hyades cluster is the nearest star cluster to Earth's solar system and scientists have long wondered if some of those stars are home to alien planets. Now, that ...
