After two days of flurries of speculation about NASA's Thursday announcement, an answer finally seems clear: NASA did not find alien life, but it did find a new life form here on Earth. A team of scientists discovered a bacteria in California that lives off arsenic.

Before you get disappointed, realize that while not as sexy as a little green man, it is a big deal. No other life form exists off arsenic. It had long been the assumption that without six certain essential elements -- carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur -- life could not exist. This discovery shows "life-as-we-know-it could be much more flexible than we generally assume or can imagine," Felisa Wolfe-Simon a NASA biochemist told the Post's Marc Kaufman.

Watch the announcement here:
