The onion-like layers of shell galaxy NGC 3923 are beautifully showcased in this image taken with the DOE-built Dark Energy Camera (DECam) on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab. Located in the constellation Hydra (the Serpent), NGC 3923 is about 70 million light-years away from Earth and 150,000 light-years across, making it about 50% larger than our Milky Way.
