Learn how features derived from Cassini radar data indicate a possible ice volcano on Saturn's moon Titan in this video from NASA. Learn about Sotra Facula, a possible cryovolcano (ice volcano) on Saturn's moon Titan. Volcanologist Rosaly Lopes explains how topographic maps derived from Cassini radar data show features (such as sand dunes, mountains, a deep crater, and lobate flow-like areas) that indicate Sotra Facula is two cryovolcanoes separated by a low area. The "magma" in cryovolcanoes is a watery mixture instead of molten rock. If there are water and heat to cause cryovolcanism, there is also the possibility of life. This video is available in both English and Spanish audio, along with corresponding closed captions. This resource is part of the NASA Planetary Sciences Collection.

Explore how astronomers and scientists use astronomical units to measure distances in the solar system in this video adapted from NASA. The astronomical unit (au) -- equal to the average distance from Earth to the Sun -- is a convenient unit of measure when talking about distances in the solar syste
