Analyzing a sample from an asteroid named Bennu reveals the chemicals necessary to form DNA and RNA.

Finally they found traces of important organic compounds like xanthine, hypoxanthine, and nicotinic acid (vitamin B3). In ...

Asteroids, small airless bodies within the inner solar system, are theorized to have contributed water and chemical building blocks of life to Earth billions of years ago. Although meteorites on Earth ...

Japanese scientists detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu ...

Scientists detected all five nucleobases -- building blocks of DNA and RNA -- in samples returned from asteroid Bennu by NASA's OSIRIS-REx mission.

Finally they found traces of important organic compounds like xanthine, hypoxanthine, and nicotinic acid (vitamin B3). In addition to suggesting that life could exist elsewhere in the universe ...
