What was discovered

Four 12 m Cherenkov telescopes in Namibia swept the Milky Way's plane in 2004-2005 and found more than a dozen new sources of very high energy gamma rays, among them supernova remnants and pulsar wind nebulae.

The result was published in Science (2005); H.E.S.S. later detected the Galactic Centre and the remnant RX J1713.7-3946. It lies near the Gamsberg.

What it led to

  • very high energy gamma-ray astronomy
  • a map of cosmic accelerators
  • the southern Cherenkov Telescope Array
