Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's essential ingredients.

NASA scientists discovered a plethora of precursors to life on the asteroid Bennu, demonstrating the importance of Earthbound sample-return missions.

The sample analysis detected 14 out of the 20 amino acids used by life on Earth to create proteins, as well as all five nucleobases essential

Uric acid is a waste product found in urine. If your body makes too much or doesn't eliminate enough of it, uric acid levels can become too high—a condition known as hyperuricemia. High uric acid levels can lead to symptoms and eventually conditions like ...

Rock and dust samples brought back from the near-Earth asteroid Bennu contain organic matter, including amino acids and all five DNA and RNA bases, as well as salts that formed early in the history of Bennu's parent body.

Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best evidence to date that such space rocks may have seeded early Earth with the raw ingredients that fostered the emergence of living organisms.
