Amateur astrophotographer Engelbert Vollmer has released a deep-exposure image of M104, the Sombrero galaxy, published as NASA's Astronomy Picture of the Day for October 5, 2026. The image reveals faint tidal streams around the galaxy, which on shorter exposures appears hat-shaped. The discovery of these extended stellar features is drawing attention among astronomy enthusiasts discussing how such structures show the galaxy's merger history.
