Story summary

Scientists detected all five nucleobases—adenine, guanine, cytosine, thymine, and uracil—in Ryugu samples.
The samples were collected by Japan's Hayabusa2 mission, linking the discovery to ancient solar system chemistry.
Researchers found similar amounts of purines and pyrimidines, indicating diverse prebiotic chemistry.
The findings align with meteorite studies and support the idea that life's molecular components may have originated in space and were delivered to early Earth.
