"Dark Energy Camera Uncovers Shell Galaxy's Layered Secrets"

The Dark Energy Camera has captured an image of the shell galaxy NGC 3923, revealing its onion-like layers of concentric rings within its galactic halo. Shell galaxies make up 10% of all elliptical galaxies and NGC 3923 is about 50% larger than the Milky Way, with the largest known shells. The image also features a gravitational lens around the galaxy cluster PLCK G287.0+32.9, which bends light and magnifies distant objects. Gravitational lenses have been used to spot ancient light and provide evidence for dark matter.
