JODRELL BANK OBSERVATORY


The Jodrell Bank Observatory is a British observatory that hosts a number of radio telescopes, and is part of the Jodrell Bank Centre for Astrophysicsat the University of Manchester. The observatory was established in 1945 by Sir Bernard Lovell, who wanted to investigate cosmic rays after his work on radar during the Second World War. It has since played an important role in the research of meteors, quasars, pulsars, masers and gravitational lenses, and was heavily involved with the tracking of space probes at the start of the Space Age. The managing director of the observatory is Professor Simon Garrington.
The main telescope at the observatory is the Lovell Telescope, which is the third largest steerable radio telescope in the world. There are three other active telescopes located at the observatory; the Mark II, as well as 42 ft (13 m) and 7 m diameter radio telescopes. Jodrell Bank Observatory is also the base of the Multi-Element Radio Linked Interferometer Network (MERLIN), a National Facility run by the University of Manchester on behalf of the Science and Technology Facilities Council.
The site of the observatory, which includes the Jodrell Bank Visitor Centre and an arboretum, is located in the civil parish of Lower Withington (the rest being in Goostrey civil parish), near Goostrey and Holmes Chapel, Cheshire, North West England. It is reached from the A535.
The Jodrell Bank Centre for Astrophysics, of which the Observatory is a part, is one of the largest astrophysics research groups in the UK. About half of the research of the group is in the area of radio astronomy—including research into pulsars, the Cosmic Microwave Background Radiation, gravitational lenses, active galaxies and astrophysical masers. The group also carries out research at different wavelengths, looking into star formation and evolution, planetary nebulae and astrochemistry.
The first director of Jodrell Bank was Bernard Lovell, who established the observatory in 1945. He was succeeded in 1980 by Sir Francis Graham-Smith, followed by Professor Rod Davies around 1990 and Professor Andrew Lyne in 1999. Professor Phil Diamond took over the role on 1 October 2006, at the time when the Jodrell Bank Centre for Astrophysics was formed. Prof Ralph Spencer was Acting Director during 2009 and 2010. In October 2010, Prof. Albert Zijlstra became Director of the Jodrell Bank Centre for Astrophysics. Professor Lucio Piccirillo was the Director of the Observatory from Oct 2010 to Oct 2011 when Prof Simon Garrington became its Managing Director.
There is an active development programme researching and constructing telescope receivers and instrumentation. The observatory has been involved in the construction of several Cosmic Microwave Background experiments, including the Tenerife Experiment, which ran from the 1980s to 2000, and the amplifiers and cryostats for the Very Small Array.It has also constructed the front-end modules of the 30 and 44 GHz receivers for the Planck spacecraft. Receivers were also designed at Jodrell Bank for the Parkes Telescope in Australia.
On 3 March 2008, it was reported that Britain's Science and Technology Facilities Council (STFC), faced with an £80 million shortfall in its budget, was considering withdrawing its planned £2.7 million annual funding of Jodrell Bank's e-MERLIN project. The project, which aims to replace the microwavelinks between Jodrell Bank and a number of other radio telescopes with high-bandwidth fibre-optic cables, greatly increasing the sensitivity of observations, is seen as critical to the survival of the establishment in its present form. Sir Bernard Lovell was quoted as saying "It will be a disaster … The fate of the Jodrell Bank telescope is bound up with the fate of e-MERLIN. I don't think the establishment can survive if the e-MERLIN funding is cut".
On Monday 14 April 2008, Cheshire's 106.9 Silk FM unveiled to its listeners their own campaign song to save Jodrell Bank, entitled "The Jodrell Bank Song" and sung by a group dubbed "The Astronomers". Along with the song, the Silk FM team also produced a music video filmed in front of the iconic Lovell telescope. Silk FM released the song for download from Monday 21 April 2008. All proceeds went towards saving Jodrell Bank.
On 9 July 2008, it was reported that, following an independent review, the STFC had reversed its initial position and would after all guarantee funding of £2.5 million annually for three years.
