PASADENA, Calif. — 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 on December 14 at the American Geophysical Union meeting in San Francisco. (more…)

A new study conducted by scientists at the Southwest Research Institute in Boulder, Colorado, has this week posited that Saturn’s rings are the remnants of a massive moon that once orbited Earth’s distant neighbour.
According to study author and astronomer Robin Canup, the moon plunged into Saturn around 4.5 billion years ago due to a giant ring of hydrogen gas responsible for creating rocky satellites but also for dragging larger moons out of orbit.
The scientific theory centres on the predominantly icy composition of Saturn’s rings, The Tech Herald reports. (more…)
