Blog Post Image: Forecast for Titan: Wild Weather Could be Ahead

This image shows the first flash of sunlight reflected off a hydrocarbon lake on Saturn’s moon Titan. The glint off a mirror-like surface is known as a specular reflection. This kind of glint was detected by the visual and infrared mapping spectrometer (VIMS) on NASA’s Cassini spacecraft on July 8, 2009. It confirmed the presence of liquid in the moon’s northern hemisphere, where lakes are more numerous and larger than those in the southern hemisphere. Scientists using VIMS had confirmed the presence of liquid in Ontario Lacus, the largest lake in the southern hemisphere, in 2008. Image credit: NASA/JPL/University of Arizona/DLR
