This artist's impression shows the planet K2-18b, its host star and an accompanying planet in this system. K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life.
University College London researchers used archive data from 2016 and 2017 captured by the NASA's Hubble Space Telescope and developed open-source algorithms to analyze the starlight filtered through K2-18b's atmosphere. The results revealed the molecular signature of water vapor, also indicating the presence of hydrogen and helium in the planet's atmosphere.
