Asteroid Ryugu Samples Contain All Five DNA and RNA Nucleobases

Scientists have detected all five fundamental nucleobases—adenine, guanine, cytosine, thymine, and uracil—in pristine samples from the asteroid Ryugu, returned by JAXA's Hayabusa2 mission. Published in Nature Astronomy, this discovery provides compelling evidence that key ingredients for life were widespread throughout the early Solar System, significantly advancing our understanding of life's potential extraterrestrial origins.
