AI Summary

A new high‑resolution 3D model created by an international team led by Dr. Brandt Gaches at the University of Duisburg‑Essen demonstrates that the uneven structure of stellar nurseries casts shadows which reshape the chemistry of the surrounding gas and dust. These shadowed regions alter the infrared emission that the James Webb Space Telescope detects. The model explains how massive young stars’ ultraviolet radiation heats gas, dissociates molecules and drives chemical cascades in photodissociation regions. The findings were published in Astronomy & Astrophysics.
