Although no compelling evidence of extraterrestrial life has yet been found, the possibility that biota might be a common feature of the universe has been strengthened by the discovery of extrasolar planets (planets around other stars), by the strong suspicion that several moons of Jupiter and Saturn might have vast reserves of liquid water, and by the existence of microorganisms called extremophiles that are tolerant of environmental extremes.
