Water vapour is spotted on a distant rocky planet

Water vapour has been detected in the atmosphere of a rocky planet 110 light-years from Earth. Called K2-18b, the planet orbits within the habitable zone of a red-dwarf star, which means that the planet could harbour life. The observations were made by astronomers at University College London, who used the Hubble Space Telescope. While the evidence for water vapour is compelling, the scientists say that the next generation of telescopes will be needed to gain a better understanding of the planet’s atmosphere.
