The Particle Physics and Astronomy Research Council (PPARC) was one of a number of research councils in the United Kingdom. It directed, coordinated and funded research in particle physics and astronomy for the people of the UK. Its head office was at Polaris House in Swindon, Wiltshire, but it also operated three scientific sites: the UK Astronomy Technology Centre (UK ATC) in Edinburgh, the Isaac Newton Group of Telescopes (ING) in La Palma and the Joint Astronomy Centre (JAC) in Hawaii. It published the Frontiers magazine three times a year, containing news and highlights of the research and outreach programmes it supports.
