New research says exoplanet could support life

Proxima B, an Earth-sized planet orbiting our nearest neighboring star, could support life, astronomers report in a new study.

Why it matters: Since the discovery of Proxima B was first announced last summer, researchers have speculated about whether life could exist on the "second Earth." It's distance from its star allows for water to exist on the surface but it also means the planet could be bombarded with X-rays and UV radiation. New climate models by researchers at the University of Exeter found Proxima B could be habitable under a range of conditions.
