Astronomers have discovered a planet 10 times the size of Jupiter -- Earth's largest neighbor -- in a solar system hundreds of light years away. But what got their attention was the fact that, based ...

The Alpha Centauri AB system is an attractive one for radial velocity observations to detect potential exoplanets. The high metallicity of both Alpha Centauri A and B suggest that they could have ...

Scientists have discovered a planet ten times the size of Jupiter orbiting two stars, scrapping previous understandings over where a planet could exist. The findings were detailed in a new study ...

Peering at distant planets is a tricky business for astronomers. There's plenty that they can assume about planets based on what they look like from afar, but it's still largely a guessing game. If a ...

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 ...

This NASA/ESA Hubble Space Telescope has given us this stunning view of the bright Alpha Centauri A (on the left) and Alpha Centauri B (on the right), shining like huge cosmic headlamps in the dark.
