The Nation's Optical Astronomy Observatory (NOAO) puts it into perspective immediately: "Eight billion years back, sun rays of sunshine from distant galaxies started their lengthy journey to Earth." You need to hold this in your mind, once we marvel in the first images from deep within the belly in our world to reach in the Chile-based Dark Energy Camera (DECam). As that title might suggest, peering at remote galaxies for purely visual gratification is not the camera's primary purpose. Caused by eight many years of planning and effort, including engineers and researchers from three continents, the DECam is installed on the Victor M. Blanco Telescope in the Cerro Tololo Inter-American Observatory in Chile. Sitting atop a 7,200-feet mountain, your camera belongs to the Dark Energy Survey, which expects to collect info on over 300 million galaxies. The aim would be to better understand dark energy -- an idea that signifies good reason why the universe's rate of expansion is accelerating, instead of slowing down because of gravity. Gaze beyond the break for that background around the project.
