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 ...

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 ...

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 ...

Imagine if we could actually make Proxima Centauri b habitable for humans.

Humans are looking to colonize the rest of the universe in Netflix’s reimagining of the 1960s sci-fi TV show “Lost in Space.” Of course, it doesn’t go very well — hence the name of the show. When ...

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 ...

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 ...

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.

Centauri A and Alpha Centauri B – they are now the “best known” stars. This has also allowed a unique and very detailed comparison between “real nature” and current stellar theory for solar-type stars ...
