NASA/JPL-Caltech/Space Science Institute

Thursday, August 29, 2013: Cassini spacecraft has now seen Titan's polar collar in ultraviolet light; previously it was observed by Voyager 2 and the Hubble Space Telescope. Researchers studying the collar’s cause and evolution believe it to be seasonal in nature. This view looks toward the Saturn-facing hemisphere of Titan. Cassini spacecraft took the image on April 13, 2013 at a distance of approximately 1.1 million miles (1.8 million kilometers) from Titan.

Strong winds of particles blow from these stars, shaping the residual gas left from a spent star formation region, creating these structures with striking appearances.
