Saturn’s Moon Enceladus

 The 2006—2007 guest lecture series continues at the San Bernardino County Museum on Wednesday evening, March 28 at 7:30 p.m. when Julie Rathbun will speak on planetary geology. The lecture, “Saturn’s Moon Enceladus,” is free and open to the public.

Enceladus is one of the innermost moons of Saturn. Its bright surface displays several types of terrain: craters, fissures, plains, corrugations, and crustal deformations. Since early 2005, the Cassini-Huygens Mission to Saturn has uncovered many mysteries about this moon. It has an atmosphere; gases may be originating from its surface or its interior.

House-sized ice boulders have a continual supply of fresh ice. Plumes of icy material stream from the south pole—possible evidence of Yellowstone-like geysers fed by liquid water. In fact, Enceladus may be the source of one of Saturn’s famous rings! Rathbun will discuss her ongoing research in planetary science, the geology of Enceladus, and how the moon’s impact craters and tectonics interact.

Dr. Julie Rathbun, as assistant professor of physics at the University of Redlands, earned her PhD in Astronomy at Cornell University. Her research on Io volcanism, Galilean satellite surface temperatures, mutual occulations between the Galilean satellites, and two-dimensional imaging of Ionian volcanoes has been supported by grants from the NASA Planetary Geology and Geophysics program and the NASA Planetary Astronomy Program.
