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:
“Brutus had rather be a villager
Than to repute himself a son of Rome
Under these hard conditions as this time
Is like to lay upon us.”
—William Shakespeare (1564–1616)
“The danger lies in forgetting what we had. The flow between generations becomes a trickle, grandchildren tape-recording grandparents’ memories on special occasions perhaps—no casual storytelling jogged by daily life, there being no shared daily life what with migrations, exiles, diasporas, rendings, the search for work. Or there is a shared daily life riddled with holes of silence.”
—Adrienne Rich (b. 1929)
“My life is superficial, takes no root in the deep world; I ask, When shall I die, and be relieved of the responsibility of seeing a Universe which I do not use? I wish to exchange this flash-of-lightning faith for continuous daylight, this fever-glow for a benign climate.”
—Ralph Waldo Emerson (1803–1882)
