Global signature of frost deposition on Enceladus revealed in colour mapping.
The top map shows a colourised map of the predicted pattern of fallout from Enceladus's icy plumes (blue represent thicker accumulations), with the global color patterns observed by Cassini imaging camera.
The bottom map is the global 3-colour map of Enceladus showing areas that are relatively bluer.
These areas correspond very well with areas predicted to have a deeper accumulation of plume-generated ice particles, or "snow".
The global color map takes advantage of Cassini's sensitivity at ultraviolet and near infrared wavelengths and shows an enhanced colour sensitivity compared to what our eyes might see.
