Cassini Finds Source of Icy Jets On Enceladus 37
Not long ago, we discussed Cassini's mission to "skeet-shoot" Saturn's moon Enceladus in order to take high-resolution pictures as close to the surface as possible. Well, NASA scientists found what they were looking for. A newly released mosaic shows 300-meter-deep fractures in Enceladus' surface which are the source of enormous icy plumes that periodically erupt into space, reaching hundreds of kilometers from the moon's surface. Another picture shows one of the fractures in closer detail.

Different wavelengths reveal different things about what they're bouncing off of. I imagine it's done to get NASA the full range of data they're looking for. If your pressing scientific question isn't "what does this look like to a human if the human were there" then there's no particular reason to pick the visual spectrum over another range of wavelengths.
