"DECam Reveals Mesmerizing Layers of NGC 3923 Shell Galaxy Amid Gravitational Lensing"

The Dark Energy Camera (DECam) has captured a stunning image of the shell galaxy NGC 3923, showcasing its concentric layers. Located in the constellation Hydra, NGC 3923 is about 70 million light-years away and is larger than the Milky Way. The galaxy's layered structure is believed to have formed through a merger with a smaller spiral galaxy, resulting in the gradual mixing of stars and the formation of concentric bands. The image also reveals gravitational lensing, allowing astronomers to study the nature of dark matter and the expansion of the universe.
