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.

This artist’s concept shows what a gas giant orbiting Alpha Centauri A could look like. Observations of the triple star system Alpha Centauri using NASA’s James Webb Space Telescope indicate the ...

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 ...

Just over four light-years away, the Alpha Centauri system holds the closest worlds beyond our own that might support life.

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 ...

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 ...
