In this May 15, 2004 image, dark regions represent areas where Cassini is seeing into deeper levels in Saturn's atmosphere. The dark regions are relatively free of high clouds and the light at these particular near-infrared wavelengths penetrates into the gaseous cloud-free atmosphere and is absorbed by methane.
