Cassini Spots Potential Ice Volcanoes on Saturn's Moon Titan

摘要

NASA's Cassini spacecraft has found possible ice volcanoes on Saturn's moon Titan that are similar in shape to those on Earth that spew molten rock. Topography and surface composition data have enabled scientists to make the best case yet in the outer solar system for an Earth-like volcano landform that erupts in ice. The results were presented at the American Geophysical Union meeting in San Francisco.
