Lunar eclipse.

It's a full moon. And 5:45pm we'll be able to see the beginning of a full lunar eclipse. I've thought for some time to try walking after work, and it would seem an ideal opportunity tonight, especially when astronomers think we will be able to see the rings of Saturn. I'm sure this type of eclipse has happened hundreds of times over the years, but it does remind us that the universe is vast, and new, to us.
