Depending on where you live last night or early this morning you could have observed a lunar eclipse. If you stayed in bed instead of watching it, you can see what it looked like through any number of videos of it posted on the web. One of the better ones I’ve seen, embedded below, is a time lapse video shot and produced by William Castleman. The video was captured in Gainseville, Florida.

A neat resource for teaching about the lunar eclipse is this simulation from Hey What’s That? that uses the Google Earth browser plugin.
