Astronomers captured first detailed images of two novae, revealing complex, staged outflows and shock-driven gamma rays, reshaping understanding of stellar explosions.
Astronomers using the CHARA Array captured the first high-resolution images of two novae, V1674 Herculis and V1405 Cassiopeiae, shortly after their eruptions, revealing complex, multi-phase outflows.
The images show perpendicular gas jets in one nova, linked to gamma-ray emission detected by NASA’s Fermi Telescope, while the other delayed outer-layer ejection for over 50 days, producing later shocks and gamma rays.
These findings, published in Nature Astronomy on December 5, 2025, challenge the long-held view of novae as simple explosions, instead showing they involve dynamic, staged ejections and powerful shock interactions, advancing understanding of stellar outbursts and multi-messenger astronomy.
Los astrónomos capturaron las primeras imágenes detalladas de dos novas, revelando flujos complejos y escalonados y rayos gamma impulsados por choques, remodelando la comprensión de las explosiones estelares.
