Proposed Indicator of Life On Alien Worlds May Be Bogus 112

sciencehabit (1205606) writes with bad news for anyone hoping to use the spectral signatures of exoplanets to determine if their atmospheres have life-enabling compositions. "Call it the cosmic version of fool's gold. What was once considered a sure-fire sign of life on distant planets may not be so sure-fire after all, a new study suggests. The signal—a strong chemical imbalance in the planet's atmosphere that could only be generated by thriving ecosystems—could instead be the combined light from a lifeless exoplanet and its equally barren moon."

    Any astronomer knows the meme "billions and billions". I think there was even a Carl Sagan skit on Saturday night live. In fact, Carl Sagan wrote a book in honor of the meme called "billions and billons"

    It is an astronomer inside joke. I made no apologizes any more than a programmer on slashdot making an inside C, or Perl or SQL joke.

Behind every great computer sits a skinny little geek.
