DNA Rocks

A rock older than life itself may hold the key to our origins.

A 2-billion-year-old asteroid is reigniting one of science’s most provocative ideas: that life on Earth may have come from the stars.

NASA and Japan’s space agency have revealed that Bennu, a carbon-rich asteroid predating any life on our planet, carries chemical precursors to DNA and RNA—and 14 of the 20 amino acids that all living organisms rely on. These molecules weren’t forged on Earth; they’ve been preserved in the ancient rock since the dawn of the solar system, whispering secrets from the cosmos.
