NASA’s Hubble Space Telescope has discovered water vapor in the atmosphere of a distant Earth-like exoplanet known as K2-18b.
The planet is located about 110 light-years away in the Leo constellation, according to a press releasefrom NASA about the exoplanet. NASA says K2-18b resides in a “habitable zone,” which is “the region around a star in which liquid water could potentially pool on the surface of a rocky planet.”
