The Hubble Space Telescope detected water vapor in the atmosphere of K2-18b

The Hubble Space Telescope detected water vapor in the atmosphere of K2-18b. This is the first time that water vapor has been identified in the atmosphere of another habitable super-Earth outside the solar system. It’s eight times the mass of the Earth, 110 light-years away, orbiting a dwarf star. At present, it is impossible to confirm other properties, and it needs further observation by future telescopes.
