Proposed Indicator of Life On Alien Worlds May Be Bogus 112

Posted by Unknown Lamer
from the exomoons-ruin-everything dept.
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.
