Using Google Earth to Hunt for Impact Craters
Google Earth has quite a few astronomy related uses, such as mapping eclipse tracks, and asteroid occultations or showing the locations of observatories. But here is one that suprised me, using Google Earth to locate asteroid/comet impact craters. It's not straight forward, you have to have check imapct databases for previous discoveries and watch out for volcanoes, but it might be a nice thing to do of an idle evening. You'd think we had found all large impact structures by now, but the Google Earth search was inspired by the discovery of a 31 Km previously undiscovered impact crater at Kebira in Egypt.
