Saturn's Ancient Rings
How old are Saturn's rings? No one is quite sure. One possibility is that the rings formed relatively recently, perhaps only about 100 million years ago when a moon-sized object broke up near Saturn. Evidence for a young ring age includes a basic stability analysis for rings, and the fact that the rings are so bright and relatively unaffected by numerous small, dark meteor impacts. New evidence, however, raises the possibility that some of Saturn's rings may be billions of years old.
In tropical astrology, 17 DEC 2007 falls under Sagittarius (♐). The sign's window runs from 11-22 through 12-21. Sagittarius points straight at the center of the Milky Way, our galaxy's brightest region. The Sun was crossing this region of the sky on 17 DEC 2007.
