Prebiotic Conditions and Search For Life
Main article: Life on Titan See also: Planetary habitabilityWhile the Cassini–Huygens mission was not equipped to provide evidence for biosignatures or complex organic compounds, it showed an environment on Titan that is similar, in some ways, to ones theorized for the primordial Earth. Scientists surmise that the atmosphere of early Earth was similar in composition to the current atmosphere on Titan, with the important exception of a lack of water vapor on Titan. The satellite is thought by some scientists as a possible host for microbial extraterrestrial life or, at least, as a prebiotic environment rich in complex organic compounds.

Famous quotes containing the words conditions, search and/or life:
“People nowadays have such high hopes of America and the political conditions obtaining there that one might say the desires, at least the secret desires, of all enlightened Europeans are deflected to the west, like our magnetic needles.”
—G.C. (Georg Christoph)
“On short, still days
At the shut of the year
We search the pathways
Where the coverts were.”
—Philip Larkin (1922–1986)
“Winter lies too long in country towns; hangs on until it is stale and shabby, old and sullen. On the farm the weather was the great fact, and men’s affairs went on underneath it, as the streams creep under the ice. But in Black Hawk the scene of human life was spread out shrunken and pinched, frozen down to the bare stalk.”
—Willa Cather (1873–1947)
