Summary

Story summary

A study published in Nature Astronomy reports that five nucleobases were found in samples from asteroid Ryugu.
The analysis was conducted by researchers from the Japan Agency for Marine-Earth Science and Technology under contamination controls.
The researchers observed differences in nucleobase abundances between Ryugu and other asteroids, which suggests ammonia's role in formation.
The findings suggest nucleobases were widespread in the early solar system, aiding understanding of life's origins.
