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 ...

Interstellar asteroids visiting our solar system from parts unknown used to be the stuff of science fiction. But today, we know of at least two such bodies Oumuamua and 2I/Borisov respectively ...

Alpha Centauri, one of the two "Pointer Stars" that help stargazers find the Southern Cross in the Southern Hemisphere, may have a planet in orbit around it. If it does, the Webb Telescope will find ...

Alpha Centauri may have a "disappearing planet', new James Webb Space Telescope observations hint. If confirmed, it could be the closest alien planet to Earth that orbits in its star's habitable zone.

Centauri A and Alpha Centauri B – they are now the “best known” stars. This has also allowed a unique and very detailed comparison between “real nature” and current stellar theory for solar-type stars ...

In a groundbreaking new study, researchers have unveiled the existence of a “cosmic highway”—a pathway of interstellar material from the Alpha Centauri system that may already be linking our solar ...

This NASA/ESA Hubble Space Telescope has given us this stunning view of the bright Alpha Centauri A (on the left) and Alpha Centauri B (on the right), shining like huge cosmic headlamps in the dark.

Within a few dozen light years of the Sun, the sky is crowded with stars that could, in principle, host living worlds. I want ...

Astronomers have used NASA's James Webb Space Telescope to find strong evidence for a planet orbiting a star in the triple system closest to our own sun. At just 4 light-years away from Earth, the ...

In humanity's search for life outside our Solar System, one of the best places to look is Alpha Centauri, a system containing the three nearest stars beyond the Sun. A new study that has involved ...

As Alpha Centauri moves away from its companion star, astronomers are training new instruments on the system -- hoping to catch sight of an elusive "superhabitable" planet. Share on Facebook (opens in ...
