And the Spirit of God moved upon the face of the waters.
Genesis 1:2
"A study entitled "A Limited Habitable Zone for Complex Life" and published in The Astrophysical Journal drastically cuts the number of planets that could potentially host intelligent life. The definition for the "habitable zone" – the distance between a planet and star – "is likely limited relative to that for microbial life" and the parameters for complex life are far more stringent.
“Imagine a ‘habitable zone for complex life’ defined as a safe zone where it would be plausible to support rich ecosystems like we find on Earth today,” said University of California Riverside professor Timothy Lyons in a statement. “Our results indicate that complex ecosystems like ours cannot exist in most regions of the habitable zone as traditionally defined.”
The extra parameters needed for complex carbon-based life to exist, such as eradicating poisonous gases (carbon dioxide and carbon monoxide) severely limit the number of exoplanets that could potentially host life, Lyons added.
To make their determination, the researchers created a model that looks at atmospheric climate and photochemistry to come up with estimated levels of carbon dioxide, a deadly, albeit necessary gas to warm the planet. In turn, they found that the tolerance for carbon dioxide levels of 0.01, 0.1, and 1 bar drops the percentage for Habitable Zone for Complex Life to 21 percent, 32 percent and 50 percent, respectively.
“To sustain liquid water at the outer edge of the conventional habitable zone, a planet would need tens of thousands of times more carbon dioxide than Earth has today,” said Edward Schwieterman, the study’s lead author, in the statement. “That’s far beyond the levels known to be toxic to human and animal life on Earth.”
