DescriptionTortola Facula - PIA13895.jpg	English: Original description: These side-by-side images obtained by NASA's Cassini spacecraft show the feature named Tortola Facula on Saturn's moon Titan. The left image was obtained by the visual and infrared mapping spectrometer data on Oct. 26, 2004, at a resolution of 2 kilometers (1 mile) per pixel This mosaic focuses on an area around 9 degrees north latitude and 145 degrees west longitude. In 2005, scientists interpreted Tortola Facula as an ice volcano. The right image shows the same feature, as seen by Cassini's radar instrument on May 12, 2008, at a much higher resolution of 300 meters per pixel. Scientists now think that this feature is a nondescript obstacle surrounded by obvious wind-blown sand dunes, similar to those commonly found in this region of Titan. In radar images, objects appear bright when they are tilted toward the spacecraft or have rough surfaces.
