The heart of the Milky Way is apparently a hotspot for molecules that combine to form RNA.
. There's no evidence of star formation there yet, but scientists believe that a star or stars will form there in the future.
The researchers used two telescopes to study the spectrum of light coming from the cloud. When certain elements or molecules absorb and re-emit light, this can be seen on the spectrum as a darker or lighter line. Interpreting these absorption and emission lines can be tricky, but it can also be used to identify which molecules are present: each one has its own spectral signature.

Building blocks for RNA-based life abound at center of our galaxyNitriles, 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.

Key Building Blocks for Life Discovered in Cloud Near Center of Our GalaxyKey precursors for life on Earth are abundant in interstellar molecular clouds and could have arrived on Earth inside comets and meteors. Nitriles, a class of organic molecules with a cyano group (a carbon atom bound with a triple unsaturated bond to a nitrogen atom) are typically toxic. But para
