Astronomers have for the first time discovered water vapour in the atmosphere of a distant planet called K2-18b.<br />”<br />”Astronomers at the University College London used data from NASA's Hubble Space Telescope to make the discovery. They yesterday published their findings in the journal Nature Astronomy.<br />”<br />”The lead scientist of the University, Prof. Giovanna Tinetti said it is the first time that they have detected water on a planet in the habitable zone around a star where the temperature is potentially compatible with the presence of life.<br />”<br />”Another astronomer Angelos Tsiaras said, it has an atmosphere, and it has water in it-making this planet the best candidate for habitability that we know right now.&nbsp;<br />”<br />”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. An exoplanet refers to a planet beyond our solar system.<br />
