Oxford, UK…Patrick Irwin, Professor of Planetary Physics (from the Atmospheric, Oceanic and Planetary Physics group here in the Oxford Department of Physics) and global collaborators spectroscopically dissected the infrared light from Uranus captured by the eight-metre Gemini North telescope on Hawaii’s Maunakea. They found hydrogen sulphide, the odiferous gas that most people avoid, in Uranus’s cloud tops. The long-sought evidence is published in the journal Nature Astronomy and can be read here.
