Liquid Methane/ethane Environment At The Surface
See also: Hypothetical types of biochemistryIt has also been suggested that life could exist in the liquid methane and ethane that form rivers and lakes on Titan's surface, just as organisms on Earth live in water. Such creatures would take in H2 in place of O2, react it with acetylene instead of glucose, and produce methane instead of carbon dioxide. By comparison, some methanogens on Earth obtain energy by reacting hydrogen with carbon dioxide, producing methane and water.

Famous quotes containing the words liquid, environment and/or surface:
“What slender Youth bedew’d with liquid odours
Courts thee on Roses in some pleasant Cave,”
—Horace [Quintus Horatius Flaccus] (65–8)
“The poorest children in a community now find the beneficent kindergarten open to them from the age of two-and-a-half to six years. Too young heretofore to be eligible to any public school, they have acquired in their babyhood the vicious tendencies of their own depraved neighborhoods; and to their environment at that tender age had been due the loss of decency and self-respect that no after example of education has been able to restore to them.”
—Virginia Thrall Smith (1836–1903)
“All beauties contain, like all possible phenomena, something eternal and something transitory,—something absolute and something particular. Absolute and eternal beauty does not exist, or rather it is only an abstraction skimmed from the common surface of different sorts of beauty. The particular element of each beauty comes from the emotions, and as we each have our own particular emotions, so we have our beauty.”
—Charles Baudelaire (1821–1867)
