Launched two years ago, the Cassini spacecraft began a journey of many years to reach and explore Saturn, the most distant planet that can easily be seen by the unaided human eye. In addition to Saturn's interesting atmosphere and interior, its vast system contains the most spectacular ring system in the solar system, numerous icy satellites with a variety of unique surface features, a huge magnetic environment teeming with particles that interact with the rings and moons, and the large, intriguing moon Titan, which is slightly larger than the planet Mercury, and whose hazy atmosphere is denser Earth's. On Friday, the lecture will be held in Pasadena City College's Forum at 1570 E. Colorado Blvd.
