Water Vapour on Habitable-Zone Exoplanet
"The team used archive data from 2016 and 2017 captured by the NASA/ESA Hubble Space Telescope and developed open-source algorithms to analyse the starlight filtered through K2-18b’s atmosphere. The results revealed the molecular signature of water vapour, also indicating the presence of hydrogen and helium in the planet’s atmosphere. "
Using #Hubble data, @UCL astronomers detected water vapour in the atmosphere of K2-18b, making it the only #exoplanet known to have both water & temperatures that could support life.
