Just saw this on CNN.com in an article about a NASA press conference planned for Thursday, and speculation over what the phrase "to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life." might mean.
. . . at least they called him a 'level-headed party pooper.'Leave it to Discover.com's level-headed Phil Plait to throw a wet space blanket on the hype over the possible discover of extraterrestrial life:
"It seems really unlikely; I don't think they would announce it in this way," he writes. "It would've been under tighter wraps, for one thing. It's more likely they've found a new way life can exist and that evidence for these conditions exists on other worlds. But without more info, I won't speculate any farther than that."
Hmfph. Party pooper.
