About this page

This page reports that Hokkaido University researchers detected urea in samples returned from asteroid Bennu by NASA's OSIRIS-REx spacecraft. Urea, an organic compound, serves as a precursor to nucleobases essential for genetic material, offering insights into the origin of life and cosmic chemistry. Analysis of approximately 0.6 grams of sample revealed high concentrations of urea and five types of nucleobases. Tohoku University researchers also discovered six types of sugars in the same samples. Bennu's samples preserve characteristics from the solar system's formation 4.6 billion years ago, providing crucial clues to understanding Earth's life origins.
