In a groundbreaking discovery, astronomers have, for the very first time, utilized data from the Keck II telescope to identify the presence of an infrared aurora on the planet Uranus.

This remarkable finding has the potential to provide crucial insights into the enigmatic characteristics of the magnetic fields within our solar system’s planets, and it might also offer an explanation for why a planet as distant from the sun as Uranus exhibits higher temperatures than expected.

The results of this research are elucidated in a study published on October 23 in the esteemed journal Nature Astronomy.

To accomplish this feat, the NIRSPEC instrument (Near InfraRed SPECtrograph) at the Keck Observatory in Hawaii was employed to gather six hours’ worth of observations of Uranus back in 2006.

The team of researchers meticulously scrutinized 224 images to identify traces of a particular particle, specifically ionized triatomic hydrogen, or H3+, Popular Science reported.

Their painstaking analysis revealed compelling evidence of H3+ formation resulting from collisions with charged particles.

The outcome of these interactions was the emergence of an infrared auroral luminescence gracefully enveloping the northern magnetic pole of Uranus.

The visual representation provided here is an artist’s rendition of this captivating infrared aurora, artfully superimposed on an image of Uranus captured by the Hubble Space Telescope.
