The Mystery of Ligeia Mare

Titan Mare FeaturesThe images above were taken by the Radar instrument aboard the Cassini spacecraft. They show the evolution of a changing feature in the large hydrocarbon sea named Ligeia Mare on Saturn’s moon Titan. The small images in the column at left show the same region of Ligeia Mare as seen by Cassini‘s radar during flybys in (from top to bottom) 2007, 2013, 2014 and 2015.

Analysis suggests that the changes in the bright features are cause by either waves, solids at or beneath the surface, or bubbles. Waves are generally thought to be the most likely explanation, but tides or sea level and seafloor changes might be the cause.

The large image panel shows all of Ligeia Mare which is Titan’s second-largest liquid hydrocarbon sea and has a total area of about 130,000 square km, making it 50 percent larger than Lake Superior on Earth.

  1. It’s global warming from all the hydrocarbons. Quick, get AL Gore on the phone!
