What in the world is it?

Cantaloupe skin? An electron microscope image of acne? Mold? Nope, it’s none of these. What you see here is the latest Cassini spacecraft’s radar image of Saturn’s largest moon Titan! The image shows the area atop Xanadu, the brightest area recorded on that Moon-sized world. This image, snapped on April 30, 2006, is roughly 150 kilometers (93 miles) wide by 400 kilometers (249 miles) long, and shows features as small as 350 meters (1148 feet).

What we see are chains of hills or mountains, with darker areas interspersed. The darker areas are regions where topographic features are either absent or partly buried. The darkest areas could contain liquids, which tend to reflect the radar beam away from Cassini in the absence of winds, making the area appear quite dark. According to NASA specialists, at Titan’s icy conditions, these liquids would be methane and/or ethane. Stubby drainage features can be see faintly between the chains of hills, suggesting flow of the liquid across parts of the region! Thgis image has since been known as Titan’s Land-o-Lakes!
