Mimas and Blue Saturn

Published.

Talented technicians often turn the images returned by space probes into works of art. This has most certainly been the case with many of the images returned by Cassini from the Saturnian system. Technicians combine images from different filters to try matching what the human eye would see.

In the foreground image, Mimas can be seen orbiting a blue Saturn. The color comes from the scattering of blue wavelengths of sunlight traveling through the atmosphere. Also visible are ring shadows. The background image is another view of the northern hemisphere with ring shadows. The northern hemisphere appears to have less cloud formations than the active southern hemisphere, perhaps because it is winter in the north.
