Westerbork Synthesis Radio Telescope Westerbork Synthesis Radio Telescope The Westerbork Synthesis Radio Telescope (WSRT) is an aperture synthesis interferometer near World War II Nazi detention and transit camp Westerbork, north of the village of Westerbork, Midden-Drenthe, in the northeastern Netherlands. It consists of a linear array of 14 antennas with a diameter of 25 metres arranged on a 2.7 km East-West line. It has a similar arrangement to other radio telescopes such as the One-Mile Telescope, Australia Telescope Compact Array and the Ryle Telescope. Its Equatorial mount is what sets it apart from most other radio telescopes, most of which have an Altazimuth mount.
John Gatenby Bolton to be quasars. It also helped transmit the video of the first Moon landing by Neil Armstrong. In 1962-63, under Bolton’s direction, this radio telescope played a key role in the discovery of the prototype of a family of very distant and luminous objects called quasars. Bolton later used it to pinpoint more than 8,000 extragalactic radio sources, including hundreds of quasars. In 1969 the instrument became the eye and ear of the world when it received the radio and television signals transmitted by Apollo 11 of man's first steps on the Moon. Bolton was made Commander of the Order
