Strange alien world found to have water

(NBC) — In a major first, scientists have detected water vapor and possibly even liquid water clouds that rain in the atmosphere of a strange exoplanet that lies in the habitable zone of its host star about 110 light-years from Earth.

A new study focuses on K2-18 b, an exoplanet discovered in 2015, orbits a red dwarf star close enough to receive about the same amount of radiation from its star as Earth does from our sun.

Previously, scientists have discovered gas giants that have water vapor in their atmospheres, but this is the least massive planet ever to have water vapor detected in its atmosphere. This new paper even goes so far as to suggest that the planet hosts clouds that rain liquid water.
