During its final close flyby of Saturn's moon Enceladus, NASA's Cassini spacecraft revisited a landscape [phys.org], and a mystery, that it had originally glimpsed more than 10 years earlier.

In views of this terrain captured during a 2005 flyby (see PIA06188), imaging scientists noticed small dark spots of an uncertain nature. Observing the same features in this false-color view, at higher resolution than before, provides some new insights. The spots are evidently large, relatively dark protrusions of solid "bedrock" ice and ice blocks scattered on and around the prominent ridge that runs across the scene from north to south (from top center toward lower left). The ice blocks range in size from dozens to hundreds of feet (tens to hundreds of meters).

The false-color view uses an ultraviolet filter centered at 338 nanometers for blue, a green filter centered at 568 nanometers for green and a near-infrared filter centered at 930 nanometers for red—thus covering a wider spectrum region than the human eye.

Looks like Earth.
