First light for Dark Energy Survey
Eight billion years ago, rays of light from distant galaxies began their long journey to Earth. That ancient starlight has now found its way to a mountaintop in Chile, where the newly-constructed Dark Energy Camera, the most powerful sky-mapping machine ever created, has captured and recorded it for the first time. A contingent of faculty, staff and students from the Department of Physics and Astronomy in the University of Pennsylvania’s School of Arts and Sciences is playing a major role in the Dark Energy Science collaboration.
