There could be (Carbon based) life on Mercury. Truly incredible. I bet there is life everywhere in our Cosmos, and I bet it won't be long until they admit it once and for all.
Sometime late next week (Dec. 3-7) they will be annnouncing the "Shocking" results from the latest Mars mission. Stay tuned!
