Astronomers using the James Webb Space Telescope (JWST) have reported a potential detection of a Saturn-like exoplanet orbiting Alpha Centauri A: the closest Sun-like star to Earth, located just over ...

Alpha Centauri, the nearest star system to the sun, is probably shedding comets and asteroids into our solar system — and even producing a few meteors in our sky. Located just 4.3 light-years from ...

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 ...

Interstellar material has been discovered in our solar system, but researchers continue to hunt for where it came from and ...

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 ...

Exoplanet hunters have had an eye on Alpha Centauri, the closest star system to Earth at just four light-years away, for decades. We know that it consists of two Sun-like stars, Alpha Centauri A and ...

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 ...

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 ...

Just 4.3 light years from Earth lies a star called Alpha Centauri A, which is famous for being the nearest star that resembles our own Sun. In the popular Avatar movies, this star's system is home to ...
