Bright night over the Gemini North Telescope (photo)

The presented image was taken by the participants of the photo expedition, the purpose of which was to photograph all the observatories operated by the NOIRLab laboratory (National Optical-Infrared Astronomy Research Laboratory). It captures the Gemini North telescope, located on top of the Hawaiian volcano Mauna Kea.

Gemini North is not the only interesting object in the picture. At the bottom left of the telescope, you can see a red light source. These are the reflections of the eruption of the Kilauea volcano, which has been going on since the end of September 2021. Even to the left you can see a green light. Its source is the city of Hilo.

It may seem that there is a snow field around the telescope. But in fact, these are clouds. They act as a kind of natural barrier protecting the top of Mauna Kea from light pollution, as well as natural light coming from both the island of Hawaii and the Pacific Ocean.

Earlier we talked about how the Gemini South telescope photographed the forming star systems.
