Take a peek at the inner workings of a world-class observatory in this image of the international Gemini Observatory, a program of NSF’s NOIRLab. Illuminated by the Moon outside this picture, the open structure of silver beams holding the secondary mirror (center) allows cool night air to pass freely between the mirrors. Combined with the open sides of the dome, the entire design ensures a uniform temperature matching the outside environment. Any variations of temperature create local turbulence that blurs astronomical images. Although this is a picture of the Gemini South telescope in Chile, its twin, the Gemini North telescope in Hawai’i is identical in its layout.
