In fact, the photo was taken at night. The illusion of the day is created due to the shooting was carried out with a long shutter speed. The illumination created by the Moon also played a role.

Vera Rubin Observatory is located on the Cerro Pachón Ridge in northern Chile. The combination of arid climate and the absence of large cities makes this region one of the best places in the world to place telescopes. Nevertheless, even here the influence of civilization is still felt. If you look closely, you can see the lights of several settlements in the background.

It is the urban illumination that is one of the main enemies of astronomy. Because of it, almost all modern ground-based telescopes are placed in sparsely populated areas.

You can also admire the magnificent photo of the night sky above the Cerro Tololo Inter-American Observatory.
