Water Discovered in the Atmosphere of a Planet Around Another Star
In a first for an exoplanet, astronomers have announced the detection of water vapour in the atmosphere of K2-18b. The planet lies in the habitable zone—a region around a star where water exists in a liquid state on a planet’s surface. It’s also an area where astronomers believe they’ll have the best chance of finding... Continue Reading →
