Jupiter is actually quite difficult to observe with #JWST's large mirror. The planet is so bright that researchers had to use clever techniques to avoid saturating the telescope's detectors.

The result of those efforts is this NIRCam image of Jupiter. The white areas are very high-altitude cloud tops. The dark ribbons north of the equatorial region have little cloud cover. Auroras, extending to high altitudes above the planet's north and south poles, are seen in red.
