CIRS Detects Warm Emissions

CIRS Detects Warm Emissions

ndogenic emissions across Enceladus' tiger stripe region determined from Cassini's Composite Infrared Spectrometer (CIRS). Purple indicates regions with temperatures no higher than that found on a surface heated only by incident sunlight, while light blue to yellow indicates regions of higher temperatures, presumably due to geologic activity. Black squares show the locations of jets identified by Cassini's Imaging Science Subsystem (ISS).

How will the diminishing sunlight affect the observed endogenic emission? Fortunately, we have less than six months to wait for the next close-up views of this geologically active corner of the Solar System.
