One of the properties that make a planet suitable for life is the presence of a weather system. Exoplanets are too far away to directly observe this, but astronomers can search for substances in the atmosphere that make a weather system possible. Researchers from SRON Netherlands Institute for Space Research and the University of Groningen have now found evidence on exoplanet WASP-31b for chromium hydride, which at the corresponding temperature and pressure is on the boundary between liquid and gas. The study is published in Astronomy & Astrophysics.
