A new study focuses on K2-18b, an exoplanet (系外行星) 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.rnPreviously, scientists have discovered gas giants that have water in their atmospheres, but this is the least giant planet ever to have water detected in its atmosphere. “The water detection was quite clear to us relatively early on,”lead author Bj?rn Benneke, a professor at the Institute for Research on Exoplanets at the Université de Montréal, told Space.com in an interview.
