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

A massive, odd planet was just discovered orbiting around two bright stars in the southern sky. It’s so weird that it’s challenging scientists’ ideas about how planets form and evolve. b Centauri is a ...

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.

Proxima Centauri b is the closest exoplanet to Earth. It is an Earth-mass world right in the habitable zone of a red dwarf star just 4 light-years from Earth. It receives about 65% of the energy Earth ...

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 ...

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 ...

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 ...

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 ...

The nearest known exoplanet to Earth, the planet orbiting Proxima Centauri, experiences some pretty nasty space weather from its parent star. But previous work on the space weather of Proxima relied ...

image: The closest star system to the Earth is the famous Alpha Centauri group. Located in the constellation of Centaurus (The Centaur), at a distance of 4.3 light-years, this system is made up of the ...
