Water found in K2-18b home environment

As reported in Nature Astronomy, K2–18b contains 0.01% and 50% water.

In astronomy jargon, K2-18b is a super-Earth, which holds its shape between Earth and Neptune. But instead of Earth's twin, K2-18b is like a cousin to our home planet.

K2-18b, which is 8 times the mass of the Earth, orbiting a star outside the solar system, according to a study published by Professor Giovanna Tanetti of the University of London (UCL), the leading scientific journal of Nature Astronomy and Research Is the only planet or 'exoplanet'

Astronomers have for the first time found water in the habitable exoplanet K2-18b environment orbiting it in the "habitable zone" of its star.
