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

A team of astronomers on Thursday provided the strongest evidence yet that a planet circles one of Alpha Centauri’s sunlike stars. The world is at the very edge of the region around the star where ...

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 ...

The blockbuster film Avatar featured a planet imagined to be circling Alpha Centauri B, the star closest to our sun. Now astronomers have discovered there really might be a system of planets there.

Astronomers have found nearly 6,000 exoplanets orbiting other stars. But for every confirmed detection, there are countless mere hints, inconclusive observations that could just as well be blips of ...

A giant planet may be orbiting the nearest Sun-like star to Earth, and the discovery is sparking excitement across the astronomy world. Using the James Webb Space Telescope, researchers have detected ...

There might be a huge planet lurking near one of the closest stars to Earth. NASA's James Webb Space Telescope (JWST) has imaged a possible planet near Alpha Centauri A, a sun-like star that forms ...

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 ...

R. Hurt (Caltech/IPAC) 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 ...

The recent discovery of a potential gas giant circling the nearby star Alpha Centauri A has led to speculation that it may be orbited in turn by a habitable moon that could support life, just like in ...

Robert Thorburn Ayton Innes, born in 1861, discovered Proxima Centauri in 1912, initially suspecting it as a third member of the Alpha Centauri system. At the time of this hypothesis, Alpha Centauri A ...
