Hubble Finds Water Vapor On Distant Exoplanet

With data from the Hubble Space Telescope, water vapor has been detected in the atmosphere of a super-Earth within the habitable zone of its host star.

K2-18b, which is eight times the mass of Earth, is the only planet orbiting a star outside the solar system (or “exoplanet”) within the habitable zone.
