Serendipity
A Traditional Eccentric!
Sorry about the title, but I could not resist it. However the scientists have found a very large valley on Mercury while sifting through the data from Messenger. See http://gizmodo.com/scientists-discovered-a-mind-boggling-chasm-on-mercury-1789147719 - and yes, this article does have links to other articles on various mercurial oddities... better stop now before the Bear notices I'm in punning modus operandi.
