The first images of Mars, captured by Webb’s NIRCam instrument on September 5, 2022. Left: Reference map of the observed hemisphere of Mars. Top right: NIRCam image showing 2.1-micron reflected sunlight, revealing surface features such as craters and dust layers. Bottom right: Simultaneous NIRCam image showing 4.3-micron emitted light that reveals temperature differences with latitude and time of day, as well as darkening of the Hellas Basin caused by atmospheric effects.
