This is replica hardware at Fermilab that was designed to help scientists mount the camera to the Blanco telescope. Image credit: Fermilab.Although the Dark Energy Camera (DECam) was built at Fermilab, it’s not there anymore. The team determined that the best place for the camera to get shots of far-off galaxies is Chile. The camera is mounted on the Victor M. Blanco telescope, which has a 13-foot-wide light-gathering mirror.
This is an image, shot with the DECam, of a star cluster 17,000 light years from Earth. Image credit: Dark Energy Survey Collaboration.The camera itself is designed to be particularly sensitive to red light (thanks to 62-charge-coupled-device array). The camera has been taking pictures since September of this year and Fermilab and the Dark Energy Survey group are sharing the images with the public.
