Animation of JWST MIRI/MRS observations of Saturn in November 2022, showing how Saturn’s appearance varies at different wavelengths. Yellows represent bright and warm parts of Saturn’s atmosphere, while the purple areas are cooler and darker. The bright north polar vortex shows up clearly in wavelengths sensing the stratosphere, whereas Saturn's banded appearance is more readily apparent at wavelengths sensing the troposphere. The spatial resolution of the images gets worse at longer wavelengths due to diffraction. A Hubble visible-light observation, acquired in September 2022, is shown in the background for comparison.
