NASA Studies Find Ribose and Glucose in Bennu, Plus Novel Organic 'Space Gum' and Rich Presolar Dust

Pristine OSIRIS-REx samples indicate the early solar system carried the ingredients for genetic molecules.

Overview

  • Peer‑reviewed analyses report ribose and, for the first time in an extraterrestrial sample, glucose within Bennu material.
  • NASA confirms the presence of nucleobases, phosphates and amino acids, completing the set of components needed to assemble RNA and DNA.
  • Researchers identify an unusual flexible organic substance—described as a rubbery, translucent “space gum”—preserved from Bennu’s parent body.
  • A separate study finds presolar grains at roughly six times the abundance measured in other astromaterials, consistent with formation in a supernova‑enriched region.
  • OSIRIS‑REx’s sealed collection and careful curation validate an extraterrestrial origin for these compounds, and scientists emphasize they are building blocks rather than evidence of life.
