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 ...

Scientists may have found the first planet ever detected around our closest “solar twin,” a star called Alpha Centauri A, the same real-life star that was home to the fictional moon Pandora in James ...

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 ...

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 A, on the other hand, is much more interesting from an Earth perspective. It's a G2V star similar to the Sun, which is a kind that we know can support a life-bearing planet because ...

Using the James Webb Space Telescope (JWST), astronomers detected a potential gas giant exoplanet, designated S1, orbiting Alpha Centauri A, a star in the closest stellar system to Earth. The ...

NASA’s James Webb Space Telescope has detected strong evidence for a giant planet orbiting Alpha Centauri A, the nearest Sun-like star to Earth. Located just 4 light-years away, this possible ...

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 ...

In some of its most ambitious work yet, the James Webb Space Telescope looked to spot a planet in a potentially habitable orbit around Alpha Centauri A, the nearest sunlike star to our solar system ...
