Webb?s Near-Infrared Camera (NIRCam) image of Neptune, taken on July 12, 2022, brings the planet?s rings into full focus for the first time in more than three decades. The most prominent features of Neptune?s atmosphere in this image are a series of bright patches in the planet?s southern hemisphere that represent high-altitude methane-ice clouds. More subtly, a thin line of brightness circling the planet?s equator could be a visual signature of global atmospheric circulation that powers Neptune?s winds and storms. Additionally, for the first time, Webb has teased out a continuous band of high-latitude clouds surrounding a previously-known vortex at Neptune?s southern pole.

Webb?s first images of Mars, captured by its NIRCam instrument Sept. 5, 2022 [Guaranteed Time Observation Program 1415]. Left: Reference map of the observed hemisphere of Mars from NASA and the Mars Orbiter Laser Altimeter (MOLA). Top right: NIRCam image showing 2.1-micron (F212 filter) reflected sunlight, revealing surface features such as craters and dust layers. Bottom right: Simultaneous NIRCam image showing ~4.3-micron (F430M filter) emitted light that reveals temperature differences with latitude and time of day, as well as darkening of the Hellas Basin caused by atmospheric effects. The bright yellow area is just at the saturation limit of the detector
