The closest exoplanets to the Solar System are around the red dwarf Proxima Centauri. This little star is orbiting two bigger ...

It would orbit within Alpha Centauri A’s habitable zone, the starlight-bathed region where liquid water can persist on a ...

NASA's James Webb Space Telescope has discovered evidence of a giant planet orbiting a star in the solar system closest to ...

Alpha Centauri is a system of three stars and the planets that revolve around them. There’s Alpha Centauri A and Alpha Centauri B, two stars that form a binary star system, and a smaller red ...

Alpha Centauri A is just 4.4 light years away, and astronomers have studied it thoroughly over the years — but if there’s a planet orbiting the nearby star, no telescope on Earth or in space ...

Alpha Centauri was the 2021 conference’s main theme, which makes sense considering that one of Breakthrough’s goals is to send a mission to our neighboring star system within the next generation.

Sandwiched in between is a 4,000-degree C layer. Astronomers have found a similar cool layer in the atmosphere of the nearby star Alpha Centauri A. ESA ...

Alpha Centauri is racing toward us at 0.007 light-years per century (80,000 kilometers per hour) and will be closest 28,000 years from now, when it will be 3.2 light-years from Earth.

Alpha Centauri is host to two sun-like stars, and a third star – the red dwarf Proxima Centauri, which is already believed to have one planet in a Goldilocks orbit, discovered in 2016.

It found the signal around Alpha Centauri A after analyzing 100 hours of data. Major caveats: The planet in question hasn’t even been named yet, and its existence has not been verified.
