A new study, published Monday in the journal
Nature Astronomy, established the chemical composition
of Uranus’ upper cloud deck for the first time. Using an
instrument called the Near-Infrared Integral Field
Spectrometer (NIFS) at the Gemini North telescope in
Hawaii, researchers determined that Uranus’ cloud cover
is composed of hydrogen sulfide (H2S) gas, which is what
gives rotten eggs their distinctive, noxious scent.
