Specular reflection off of a Titan lake On 8 July 2009, Cassini finally saw the telltale glint of sunlight specularly reflecting off of the mirror-like surface of a lake on northern Titan. This image is from the VIMS instrument employing infrared light at a wavelength of 5 microns, and has been colorized to match visible-light pictures of Titan.
