Alien Planet 48 Light-Years Away Is A Water World, Suggest NASA?s Webb

Scientists using the James Webb Space Telescope have concluded that a nearby exoplanet could be the best candidate yet to find water—and even an Earth-like atmosphere.

Over 5,000 exoplanets—planets that orbit stars other than our sun—have so far been discovered, but relatively few are close enough to study in detail. Just 49 light-years distant in the constellation Cetus, LHS 1140 b is 1.7 times the size of Earth. 

With the discovery, LHS 1140 b becomes one of the most promising exoplanets yet in the search for liquid water beyond the solar system.
