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.

A sunlike star next door called Alpha Centauri A may host a huge planet, researchers report in two studies in press in Astrophysical Journal Letters. The planet candidate orbits in its star’s ...
