Did Asteroids Invent Gum Billions of Years Ago? (www.universetoday.com)

Researchers analyzing samples from the asteroid Bennu collected by the OSIRIS-REx spacecraft have discovered a nitrogen-rich polymer, informally dubbed "space gum." This finding challenges existing models of asteroid formation and suggests that complex organic molecules may have originated in space. The polymer’s unique structure contains amides, critical building blocks for amino acids, and exhibits a higher oxygen and nitrogen content than typical asteroid samples, which predominantly consist of carbon and hydrogen. The study proposes a “Cold-First” theory for the polymer's formation, indicating that it developed in a low-temperature environment before encountering hydrothermal activity. This suggests that the conditions on Bennu played a vital role in preserving these molecules, which would typically break down when exposed to heat and water. The implications are significant for the AI/ML community as this research enhances our understanding of organic chemistry in extraterrestrial environments and strengthens the hypothesis that key life precursor chemicals can form in space, paving the way for future explorations of life's origins beyond Earth and prompting potential AI applications in modeling such complex chemical processes in astrobiology.
