Recent research suggests that our solar system could already be hosting alien probes, potentially observing us from a distance. This idea aligns with a 2023 statement from a Pentagon UFO chief who ...

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 ...

The most crowded alien planetary system found yet possesses five worlds all orbiting a star at least 12 times closer than Earth does the sun, researchers say. Investigators discovered these exoplanets ...

Harvard’s UFO-hunting astronomer Avi Loeb says interstellar object 3I/ATLAS still has strange, unresolved clues - from its near-perfect planetary-plane path to odd jets ...

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 ...

A Harvard astronomer is making waves by suggesting that a massive interstellar object hurtling through our solar system might be an alien spacecraft.

Scientists have long suspected that other solar systems are made of the same things as ours. Indeed, the more we look, the more these alien solar systems start to look like our own. Continuous ...

3I/ATLAS, a mysterious interstellar object racing toward the Sun, is baffling scientists with its speed and origin. Some researchers suggest it could even be alien-made, drawing comparisons to probes ...

There’s a visitor in town, and its name is 3I/ATLAS. The presumed interstellar comet presents a rare opportunity for astronomers to study an object born a long time ago in a star system far, far away.

Astronomers found no radio signals from the comet that would suggest it is an extraterrestrial spacecraft. 3I/ATLAS was confirmed as the third known object to enter our solar system from interstellar ...

If life exists elsewhere, it might not be on worlds like Earth. Here are some of the more peculiar places scientists are looking.
