Astronomers used NOIRLab’s Dark Energy Camera to capture a massive survey of the Milky Way galaxy’s galactic plane that contains a gargantuan 3.32 billion celestial objects. The original image from the US Department of Energy-fabricated Dark Energy Camera at the NSF’s Cerro Tololo Inter-American Observatory in Chile was reproduced in 4,000-pixels to fit on smaller devices.
The Dark Energy Survey (DES) basically uses images taken in the near-ultraviolet, visible, and near-infrared to measure the expansion of the universe using Type Ia supernovae, baryon acoustic oscillations, the number of galaxy clusters, and weak gravitational lensing. Technically speaking, it’s equipped with scientific sensor array consisting of 62 2048×4096 pixel back-illuminated CCDs totaling 520 megapixels as well as an additional 12 2048×2048 pixel CCDs (50 Mpx) are used for guiding the telescope, monitoring focus, and alignment.
