For the first time, astronomers have peered into the atmosphere of an exoplanet – a planet outside our solar system – and discovered both water vapor and temperatures that could potentially support life, according to a new study.

The exoplanet, known as K2-18b, is eight times the mass of Earth and known as a super-Earth, or exoplanets between the mass of Earth and Neptune. It orbits a red dwarf star 110 light-years away from Earth in the Leo constellation. The planet was first discovered in 2015 by NASA’s Kepler spacecraft.
