Hubble Space Telescope has discovered water vapour for the first time in the atmosphere on an exoplanet in the goldilocks zone around a star 110 light years away. If confirmed with further studies, This will be the first known planet with water discovered in a planet in the habitable zone The habitable zone is the region around a star where its not too hot or not too cold for liquid water to exist on a planet.


The planet named K2-18b is a Super-Earth, 8 times more massive than the Earth and orbits a small red dwarf star in the constellation Leo.


This is not to say that there is actually liquid water on the surface of this planet as its not known if this planet is a rocky world like our Earth or a gaseous planet like a smaller version of Neptune. Liquid water though means its a candidate for life on another world. It would be very different to life on Earth with the surface gravity several times that of Earth's surface gravity. However this is life in deep oceans of the Earth where water pressure is hundreds of atmospheres.​
