Probing the Surfaces of Alien Waters: Cassini Reveals Possible Evidence of Waves on Seas of Titan

An image of Kivu Lacus, a small lake on Titan’s northern hemisphere, taken in infrared wavelengths in July 2012 with Cassini’s VIMS instrument from a distance of approximately 30,000 km. The bright spot indicates a specular reflection of sunlight from the surface of Kivu Lacus, which could result from the formation of waves. […]
