The Gemini Observatory is a significant astronomical facility consisting of twin telescopes located on two high-altitude sites: Mauna Kea in Hawaii and Cerro Pachón in Chile. These locations provide exceptionally clear skies for observing due to their high altitudes and remote positions, which minimize light pollution and atmospheric disturbances. Each telescope has an 8.1-meter diameter mirror, enabling the collection of light from distant astronomical objects. This design enhances the observatory’s capability to conduct a wide range of scientific investigations across the electromagnetic spectrum from visible light to infrared.
