Supercomputing Dark Energy Survey Data through 2021

Scientists' effort to map a portion of the sky in unprecedented detail is coming to an end, but their work to learn more about the expansion of the universe has just begun. "Using the Dark Energy Camera, a 520-megapixel digital camera mounted on the Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory in Chile, scientists on DES took data for 758 nights over six years. Over those nights, the survey generated 50 terabytes (that's 50 trillion bytes) of data over its six observation seasons. That data is stored and analyzed at NCSA. Compute power for the project comes from NCSA's NSF-funded Blue Waters Supercomputer, the University of Illinois Campus Cluster, and Fermilab."
