Scientific First: Water Found On Planet Outside Our Solar System

For the first time, scientists searching for extraterrestrial life have found an exoplanet (a planet outside our solar system) that has water. Two new studies found that K2-18 b, which lies 110 light-years from Earth and orbits a red dwarf star, has water vapor and possibly even liquid water clouds, as Space.com reports.

Space.com notes, “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.”
