A few years ago the life forms around deep-ocean thermal vents were a surprise. Now ancient <a href="http://www.princeton.edu/pr/pwb/99/1213/microbe.shtml">bacteria alive in rock 2 miles down have been found.</a> The story is in the <a href="http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2002/12/09/MN154689.DTL&type=science">San Francisco Chronicle.</a> It is also at <a href="http://www.nature.com/nsu/021209/021209-1.html">Nature.Com</a>. Other bacteria survived frozen in the pressures of an ocean 100 miles deep. This increases the known limits of where life can exist on any planet. People always used to say that life is a miracle because life is so hard to come by. I tend to disagree and think that life strives all the time to take over a new environment, or an environment inaccessible to humans. These types of stories always wake up the kid in me who thinks there's got to be some form of life on Mars, Europa, and other celestial bodies.
