When NASA announced that they were going to hold a press conference about "an astrobiology finding that will impact the search for extraterrestrial life," I was pretty excited--especially when I read that the details had been embargoed (that is, people at the journal publishing the paper weren't allowed to talk about it ahead of time). To make sure we got the hint, NASA reminded readers that "Astrobiology is the study of the origin, evolution, distribution and future of life in the universe."
