Water found for the first time on potentially habitable planet
Water has been discovered for the first time in the atmosphere of an exoplanet with Earth-like temperatures that could support life as we know it, scientists revealed on Wednesday. K2-18b is is one of hundreds of so-called “super-Earths”. It is eight times the mass of Earth and twice as big. It orbits in its star’s “habitable zone” at a distance where water can exist in liquid form, report in the journal Nature Astronomy said. Of the more than 4,000 exoplanets detected to date, this is the first known to combine a rocky surface and an atmosphere with water.
