Uracil in the carbonaceous asteroid (162173) Ryugu - Nature Communications

Uracil was identified in the sample returned from the asteroid Ryugu. Having been provided to the early Earth as a component in such asteroidal materials, these molecules might have played a role for prebiotic chemical evolution on the early Earth

Peptides on Stardust May Have Provided a Shortcut to Life | Quanta Magazine

The discovery that short peptides can form spontaneously on cosmic dust hints at more of a role for them in the earliest stages of life’s origin, on Earth or elsewhere.
