Uranus Aurora

The Keck II Near-Infrared Spectrometer (NIRSPEC) telescope in Mauna Kea, Hawaii is the 1^st to see the infrared glow on Uranus, caused by hydrogen molecules in its atmosphere becoming excited.

Aurora formations - Charged particles from the solar wind engage with magnetic field of Uranus, steering them towards its magnetic poles.
When these particles enter Uranus atmosphere, they collide with its atmosphere molecules, setting them glow.
Aurora colour - It is predominantly at ultraviolet and infrared wavelengths as dominant atmospheric gases in Uranus are hydrogen and helium at much lower temperatures than on Earth.

On Earth, the auroral light comes from collisions with oxygen and nitrogen atoms, with the colours mostly red, green and blue.

The ultraviolet aurora on Uranus was first seen in 1986 by NASA's Voyager 2 probe, which flew past the planet.
The Uranus molecular hydrogen gets ionized and forms H3+ cations following collisions with charged particles, with the emission creating an infrared auroral glow over the northern magnetic pole.
