An article published in the journal "Nature Astronomy" reports the discovery of the five nucleobases that form DNA and RNA—adenine, guanine, cytosine, thymine, and uracil—in samples brought back to Earth from asteroid Ryugu. A team of researchers analyzed two of the samples taken by JAXA's Hayabusa 2 space probe during its mission. The five nucleobases were found in both samples. Just over a year ago, the detection of the five nucleobases in samples brought back from the asteroid Bennu by NASA's OSIRIS-REx space probe was announced. This provides further confirmation of the presence of life's building blocks on asteroids, and it's possible that they seeded the primordial Earth.
