What if humanity had no choice but to leave the solar system? Just 4.2 light-years away, Proxima Centauri B could be our closest chance at survival. It sits in the habitable zone, but the reality is ...

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 ...

Proxima Centauri b is the closest exoplanet to Earth. It is an Earth-mass world right in the habitable zone of a red dwarf star just 4 light-years from Earth. It receives about 65% of the energy Earth ...

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) ...

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 ...

If there is life on Proxima Centauri b, it could take the Extremely Large Telescope as little as 10 hours to detect its influence on the planet’s atmosphere. Observations will take longer for planets ...

The rocky planet circling the closest star to the sun got hammered by a superpowerful flare last year, a new study reports. That's a bit of bad news for anyone hoping that the alien world, known as ...

Planets like Proxima Centauri b experience tides hundreds of times stronger than ones that move Earth’s oceans twice a day. The force of those tides also tugs on the planet’s atmosphere, but a recent ...

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 ...

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 ...
