Proxima Centauri b is the closest known exoplanet that could be in the habitable zone of its star. Therefore, it has garnered ...

The James Webb Space Telescope has just unveiled the clearest image ever captured of Proxima B, a potentially habitable exoplanet located just 4.2 light-years away from Earth. This groundbreaking ...

If Proxima b is positioned so that it moves across Proxima Centauri’s stellar disk, there’s a chance that observatories including NASA’s yet-to-be-launched James Webb Space Telescope could ...

Proxima Centauri b will surely become the archetype for understanding more distant Earth-size, and possibly Earth-like, planets all across our galaxy. The effort needed to study it will be ...

Proxima Centauri b --- the newly-discovered earth-mass planet once thought to be a real contender for habitability --- is, in fact, very likely to be uninhabitable, a new study concludes.

The planet, called Proxima Centauri b, orbits its star every 11.2 days. That puts it in the “habitable zone,” where liquid water could (could) exist on the surface.

Proxima b orbits around Proxima Centauri (lower right), the closest stellar neighbor to our own sun. Proxima Centauri is about 4.22 light-years from the sun, ...

Proxima Centauri b is the closest world beyond our solar system that we know of, but scientists are checking to see if it's alone. Eric Mack has been a CNET contributor since 2011. Eric and his ...

Proxima Centauri is notable because red dwarves are the cosmos’ most abundant type of star. If the Milky Way held just 100 stars — it actually has 100 billion — 75 of them would be these ...
