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.

European astronomers have discovered a planet with about the mass of the Earth orbiting a star in the Alpha Centauri system — the nearest to Earth. It is also the lightest exoplanet ever discovered ...

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 ...

The Centauri system: Alpha Centauri A is the bright star to the left, Alpha Centauri B is the bright star to the right, and Proxima Centauri is circled in red. A team led by Kevin Wagner from 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 ...

Our nearest neighbor, Alpha Centauri, is 4.37 light-years from Earth, which is super close from a cosmological perspective but achingly far from a human point of view. A new telescope promises to ...

The star system closest to our own sun hosts a planet with roughly Earth's mass and may harbor other alien worlds as well, a new study reports. Subscribe to read this story ad-free Get unlimited ...

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 ...

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 ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. This article is more than 5 years old. Alpha Centauri A ...

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 ...

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 ...
