It is a small rock stuck in an asteroid belt between Mars and Jupiter, it is barely a dwarf planet and has been largely ignored. Now though as the tractor sized probe Dawn obits this tiny little planet it is suddenly the subject of speculation after two mysterious lights were found shining from its surface, and today a 3-mile high pyramid-shaped object was spotted. This speculation runs from an alien civilization, to a deposit of ice or salt reflecting light. I have my own theory and it is fairly simple – we left something behind on our planet hop to Earth. Hey… makes about much sense as Aliens, right?
