With the release of hi res pics from our space probes, a fellow can sit at the computer and explore our small part of the universe these days. What we are finding is some really mind boggling stuff. This is a pic taken by the Cassini probe of Iapetus, one of Saturns moons. Check out the ridge that runs nearly all the way around the moon at the equator. It's about 12km wide, and a little more than that high. Looks like someone built a moon in 2 pieces, and then welded it together. Weird but totally cool.
