Nitriles, a class of organic molecules with a cyano group—that is, a carbon atom bound with a triple unsaturated bond to a nitrogen atom—are typically toxic. But paradoxically, they are also a key precursor for molecules essential for life, such as ribonucleotides, composed of the nucleobases or "letters" A, U, C, and G joined to a ribose and phosphate group, which together make up RNA. Now, a team of researchers from Spain, Japan, Chile, Italy, and the US show that a wide range of nitriles occurs in interstellar space within the molecular cloud G+0.693-0.027, near the center of the Milky Way.
