The third-brightest star in the sky, Alpha (α) Centauri, gleams in the southern constellation Centaurus. Since it is positioned at a declination of almost –61°, only stargazers located south of ...

Astronomers have found evidence of a third planet around the closest star to the sun, reinforcing the idea that planets are common around the stars of the galaxy, even some of its smallest. And while ...

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 ...

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) ...

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 ...

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 ...

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 ...

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 ...

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 ...

Looking back from a distance, whether that be time or physical separation, can provide us with a fresh perspective on who we are and how far we've come. In our daily lives, Earth appears flat and ...
