If you thought that the mesmerizing auroras are exclusive to Earth, think again. Gas giants like Uranus and Saturn also boast their own versions of the Northern Lights. Recently, the University of Reading revealed plans to utilize the James Webb Space Telescope to unravel the mysteries behind these celestial phenomena.
A team spearheaded by the University of Leicester secured observation time with the Webb Telescope for two initiatives focusing on the auroras of Saturn and Uranus. Among nearly 2,000 submissions, their proposals stood out and earned approval under the Webb Cycle 3 General Observer Program.
Similar to Earth, the auroras on these planets are triggered by energetic charged particles that interact with the planets' atmospheres via magnetic field lines. James O'Donoghue, a planetary scientist at the University of Reading, expressed excitement about this rare opportunity to utilize the cutting-edge telescope. The team aims to investigate Saturn's unique version of the northern lights, potentially linked to enigmatic winds swirling in a figure-of-eight pattern. By mapping temperature variations across Saturn's auroras, they hope to unravel the mechanisms driving this stunning phenomenon.
The researchers' project entails capturing images of Uranus over a single day or a full rotation in 2025. This comprehensive mapping effort aims to determine whether auroral emissions result from solar wind interactions, akin to Earth, or if an internal source, like Jupiter, is at play.
