Astronomers aren't sure where they came from or how old they are. Some evidence suggests they formed only a few hundred million years ago--a time when dinosaurs roamed the Earth. Before then Saturn might have been a ring-less planet. I've posted this several times and so far no-one's responded, and my own searches haven't found anything. Who was the British astronomer Arthur Clarke mentions in "2001 A Space Odyssey" as saying in 1945 that the rings might be only 2 or 3 million years old ? [Oops. That was a bit convoluted !] Or was Clarke making it up for the story ? -- "Forty millions of miles it was from us, more than forty millions of miles of void" |

Most people are not in the situation to access viewing it in the pre-dawn sky. With opposition, Saturn is up all night, and afterwards, it is definitely more convenient to view for most people. It is closest to the Earth near opposition and thus will have an angular diameter (20.9" arc) which is larger than it is currently (its disk will be over 20" arc in diameter for about a month and a half either side of opposition). It will be in a good position to view, as from opposition on towards quadrature, Saturn's declination will be increasing slightly, making it a good period of observations for observers in the northern hemisphere (it will transit at over 62 degrees above the horizon for much of the U.S.). In fact, it will be reasonably good for probably three months either side of the date of opposition. There is really no "best" time, other than the time when it will be convenient for the observer to watch it and when it is best placed for viewing (ie: highest above the horizon). Clear skies to you. -- David W.
