Ryugu Sample Reveals Diverse PAHs, Insights for Astrochemistry

4/16/2026

Summary

Story summary

The researchers analyzed the dichloromethane (DCM) extract from the Ryugu sample and found abundant polycyclic aromatic hydrocarbons (PAHs).
Using atomic force microscopy (AFM), they identified a variety of PAHs, including surprisingly large molecules with three-dimensional structures.
PAHs ranged from small rings to larger compounds with over 100 rings, and the results suggest these molecules could inform astrochemistry and organic matter formation in space.
