Toxic Hydrogen Cyanide And Its Role In The Origins Of Life

Saturn's moon Titan is a frigid world with a thick atmosphere. Its thick clouds contain significant amounts of hydrogen cyanide (HCN). Research shows that in cold environments, the surface of HCN crystals assist the formation of organic molecules, which are also present on Titan. What does this mean for our understanding of the origins of life? Image Credit: Cassini Orbiter/NASA, JPL-Caltech and University of Arizona

Hydrogen Cyanide, which is toxic, may have played an important role in the emergence of life. Its unique properties, especially in frigid environments in space, may have helped generate the complex molecules necessary for life to appear.
