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) ...

Proxima Centauri, our nearest stellar neighbor, hosts a potentially habitable planet, Proxima B. Reaching it is a colossal ...

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 ...

In August astronomers announced that the nearby star Proxima Centauri hosts an Earth-sized planet (called Proxima b) in its habitable zone. At first glance, Proxima Centauri seems nothing like our Sun ...

The closest star to Earth, Proxima Centauri (PC), is still about 8000 times further away from us than Pluto. Propelling a probe to PC will require a much higher cruising speed than we can currently ...

The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri. These new observations reveal the glow coming from cold dust in a region between one to ...

The Extremely Large Telescope (ELT), currently under construction in northern Chile, will give us a better view of the Milky Way than any ground-based telescope before it. It's difficult to overstate ...

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 ...

The nearest star to Earth is, of course, the sun. The nearest star system to Earth, beyond the sun, is the interesting star system known as Proxima Centauri. A red dwarf star located 4.244 light years ...

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 ...
