The effect of Gegenschein

In the upper right of this fisheye fulldome picture, a faint sky glow effect known as Gegenschein is visible over the Very Large Telescope (VLT). The VLT is based at the Cerro Paranal site in the Atacama Desert of northern Chile, and it houses four 8.2-metre Unit Telescopes known as Antu, Kueyen, Melipal and Yepun, shown here lined up in front of a stunning starry backdrop.
