"Newly Discovered Infrared Aurora on Uranus Provides Insights into Icy Worlds"

Astronomers have discovered a new aurora on Uranus, the first of its kind to be observed in infrared wavelengths. The aurora was detected using the Keck II Telescope's Near-Infrared Spectrograph, and its presence was revealed through analysis of the ion H3+ in the data. This discovery marks a significant milestone in the study of auroras on Uranus and will contribute to our understanding of ice giant auroras and planetary magnetic fields. Further research on Uranus' aurora could provide insights into the planet's atmosphere and the shifting of its poles. A proposed probe to Uranus would help map its gravitational and magnetic fields, but it is not expected to launch until 2031 or 2032.
