Quick. What's the closest star after the sun? If you said Alpha Centauri you're one-third correct. Alpha is actually a triple system comprised of Rigil Kentaurus (Alpha Centauri A), Toliman (Alpha B) ...

A search was conducted for laser signals, both sub-second pulses and continuous emission, from the regions of the sky opposite Proxima and Alpha Centauri. These regions are located at the foci of 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 ...

Proxima Centauri is an M dwarf approximately 15,000 AU from the Alpha Centauri binary, comoving and likely in a loosely bound orbit. Dynamic simulations show this configuration can form from a more ...

Astronomers have found nearly 6,000 exoplanets orbiting other stars. But for every confirmed detection, there are countless mere hints, inconclusive observations that could just as well be blips of ...

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.

Ever since we found an exoplanet around the nearest star from Earth, there's been intense interest in whether it could host life. Today's news points in the opposite direction. Share on Facebook ...

An artist's impression of a flare from Proxima Centauri, modeled after the loops of glowing hot gas seen in the largest solar flares. Exoplanet Proxima b is shown in the foreground. Proxima b orbits ...

What can star variability—changes in a star's brightness over time—teach astronomers about exoplanet habitability? This is what a recent study accepted for publication in The Astronomical Journal ...

Proxima Centauri (Latin , meaning "next to" or "nearest to") is a red dwarf about 4.24 light-years from the Sun, inside the G-cloud, in the constellation of Centaurus. It was discovered in 1915 by ...
