Astronomers have made an exciting discovery—a new Earth-like exoplanet, Proxima b, located in the Alpha Centauri system. This ...

Proxima Centauri, just 4.24 light-years from Earth, is the closest known star to our Sun. Though it’s the smallest member of ...

As Proxima Centauri is a red dwarf star it will bathe its orbiting planet in a pale red glow. [3] The detection reported today has been technically possible for the last 10 years.

In that case, Proxima b might be like Earth’s Moon – located in the habitable zone, but not at all friendly to life. “Direct observations of Proxima b won’t happen for a long time.

Scientists haven't been able to spot Proxima b transiting its star yet, but a new study of the Proxima Centauri system shows how Proxima b could be a habitable ocean planet.

Ideas for interstellar travel abound, but the gap between theory and practice stretches from here to Proxima Centauri. Even if Proxima b is habitable, we're a long way from any potential mission.

Alpha Centauri is about 4.4 light-years (roughly 25 trillion miles, or 40 trillion kilometers) from Earth and is home to three separate stars.

Our closest planetary neighbor, Proxima Centauri b (located in the Alpha Centauri system four light-years away), is probably a tidally locked M-Earth. Unlike our Earth, M-Earths have no days, no ...
