” The NASA/ESA/CSA James Webb Space Telescope has actually offered us some infrared pictures of the aurora, however Juno is the very first spacecraft in a polar orbit around Jupiter,” stated Dr. Ali Sulaiman, a scientist at the University of Minnesota.

“The area around allured worlds like Jupiter is filled with plasma, a superheated state of matter where atoms get into electrons and ions.”

“These particles are sped up towards the world’s environment, triggering the gases to illuminate as an aurora.”

“On Earth, this shows up as familiar green and blue lights.”

“However, Jupiter’s aurora is normally undetectable to the naked eye and can just be observed utilizing UV and infrared instruments.”

The group’s analysis exposed that due to the incredibly low density of Jupiter’s polar plasma integrated with its effective electromagnetic field, the plasma waves have a really low frequency, unlike anything formerly observed around Earth.

“While plasma can act like a fluid, it is likewise affected by its own electromagnetic fields and external fields,” stated University of Minnesota’s Professor Robert Lysak.

“Our research study likewise clarifies how Jupiter’s intricate electromagnetic field enables particles to flood into the polar cap, unlike Earth where the aurora forms a donut pattern of auroral activity around the polar cap.”

“We wish to collect more information as Juno continues its objective to support more research study into this brand-new phenomenon.”

The group’s outcomes were released July 16, 2025 in the journal Physical Review Letters
