Iapetus…moon of mystery…and nuts?

Greetings and Salutations….

Well, The universe continues to offer strangeness. I must admit that I was not aware that Jupiter’s moon Iapetus had a very tall ridge of peaks around its equator until I ran across this story on The Register that talks about how it adds the oddness of making the moon rather resemble a walnut, and, how it formed. It is an interesting universe!
