Building blocks for life found in rocks collected from asteroid Bennu

Studies of rocks and dust collected from Bennu, an asteroid orbiting Earth, have revealed clues about how life may have first formed on Earth. A NASA mission collected the sample and brought it back in 2023, and scientists have found traces of ancient brine that contains minerals that are the raw ingredients of life.
