spaceplasma:Enceladus nightshine & plumesNarrow-angle false color composite taken on 2006-03-22 using infrared (IR3), green and ultraviolet (UV3) filters. Because the far infrared filter was used, at wavelengths in which Saturn is less bright than in the green filter, the saturnlit portion of Enceladus looks greenish here.The rings present their unlit side with the F ring showing a brilliant white color while the main rings are darker and more brownish. A hint of the G ring can be seen beyond the F ring.Credit: Gordan Ugarkovic -- source link
