Summary

Story summary

The CHARA Array at Georgia State University produced images of two nova explosions detected in 2021: V1674 Herculis and V1405 Cassiopeiae.
Using near-infrared interferometry, researchers captured early post-explosion phases and observed complex ejecta flows.
A new ejecta flow coincided with gamma rays detected by NASA's Fermi Space Telescope, signaling a powerful shock.
The findings broaden understanding of these transient events.
