Ammonia as a Possible Solvent for Life

  • Ammonia (NH4), is abundant in the universe, and a strong candidate as a hypothetical alternative solvent to water.
  • At Earth-like pressures, ammonia is liquid only at extremely low temperatures, so hypothetical life using ammonia as a solvent might thrive in freezing (relative to water) temperatures.
  • Ammonia/water mixtures also have liquid temperature ranges (at normal pressures) well below that of just water.
  • Titan, moon of Saturn, is believed to have subsurface oceans of a liquid ammonia/water mixture.
