Sombrero Galaxy reveals enormous diffuse halo in new deep-sky image

Astronomers using the 570-megapixel Dark Energy Camera in Chile captured a vast, diffuse halo around the Sombrero Galaxy (M104), extending far beyond its dusty disk and revealing a faint stellar stream that suggests past interactions with a smaller satellite galaxy. The image showcases both the bright central bulge and the faint outer structures in one frame, thanks to the camera’s sensitivity to extremely faint light.

Sombrero Galaxy reveals a colossal halo and faint stellar stream in a new deep-sky image

A new 570-megapixel image from the Dark Energy Camera at Cerro Tololo reveals an enormous, diffuse halo around the Sombrero Galaxy (M104) that extends beyond the bright disk by more than three times, plus a faint stellar stream suggesting past interactions with a smaller satellite. The image also sharpens the central bulge and dust lanes, highlighting star formation regions and the galaxy’s distinctive hat-like shape, thanks to NOIRLab’s deep-sky imaging capabilities, building on recent JWST mid-infrared observations.
