説明 | This artist’s impression shows the planet K2-18b, its host star and an accompanying planet. K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life. Researchers used archive data from 2016 and 2017 captured by the 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.Credit: ESA/Hubble, M.
