Astronomers have discovered eight new exoplanets that may be capable of supporting life as we know it, including what they say are the two most Earthlike alien worlds yet found.

All eight newfound alien planets appear to orbit in their parent stars’ habitable zone — that just-right range of distances that may allow liquid water to exist on a world’s surface — and all of them are relatively small, researchers said.

“Most of these planets have a good chance of being rocky, like Earth,” study lead author Guillermo Torres, of the Harvard-Smithsonian Center for Astrophysics (CfA), said in a statement. [10 Exoplanets That Could Host Alien Life]
