How strange that this was reported on today, it’s been a couple of months since we published this paper. I love to see it, but I’m deep into processing our Uranus data right now, so this turned me backwards!
I never heard of this Saturn spin issue before. Happy to read that again JWST gets the job done!
Northern lights heat the atmosphere, creating powerful winds, that give the illusion of a varying rotational rate.
> A decades-old mystery about Saturn has finally been solved thanks to the James Webb Space Telescope. Scientists discovered that Saturn’s changing “rotation rate” was never caused by the planet speeding up or slowing down, but by powerful winds high in its atmosphere. Webb’s unprecedented observations revealed that Saturn’s northern lights actively heat the atmosphere, creating winds that generate electrical currents, which then power the aurora all over again in a self-sustaining cycle.
