On July 26, 2012, the High Energy Stereoscopic System (H.E.S.S.) II telescope started operation in Namibia. Dedicated to observing the most violent and extreme phenomena of the universe in high-energy gamma rays, H.E.S.S. II is the largest Cerenkov telescope ever built — the new portion has a 92-foot-diameter (28 meters) mirror. Together with the four smaller (12 meter) telescopes already in operation since 2004, the H.E.S.S. observatory will continue to define the forefront of ground-based gamma-ray astronomy and will allow deeper understanding of known high-energy cosmic sources such as supermassive black holes, pulsars and supernovae, and the search for new classes of high-energy objects.
