Illustration for article titled Saturn Dominates Dione in this Striking New Photo From NASA

Saturn’s satellite Dione is less than half the size of our moon, and it orbits a planet which features a radius nine times that of Earth. It’s a stark contrast in size that’s beautifully conveyed in a picture recently captured by the Cassini space probe.

Saturn appears hazy compared to Dione owing to the image being acquired via a wavelength absorbed by methane. Dione, unlike Saturn, does not experience methane absorption, so the light simply bounces off its icy surface.
