For the First Time, Water Was Detected in This Habitable Exoplanet
In the atmosphere of this exoplanet, which is 111 light years away, astronomers made an amazing discovery: water. It is known that about 50% of the exoplanetary atmosphere called K2-18b is filled with water vapor. However, unlike other giant exoplanets that have water in their atmosphere, K2-18b belongs to the Super Earth group and the habitable zone. It has rocky surfaces like Earth, Mars and Venus. "Finding water other than on Earth is very exciting," said Angelos Tsiaras, an astronomer at University College London.

We know that it orbits the red dwarf star K2-18 quite closely - one rotation of about 33 days. It's not so hot that the water doesn't evaporate from the surface, nor is it so cold that it doesn't freeze. It is known that the rate of star irradiation in K2-18b is similar to...
