Jodrell Bank is famous for its landmark radio telescopes. These telescopes detect radio waves emitted by astronomical sources in the sky.
There are 4 radio telescopes at Jodrell Bank. These are The Lovell, Mark II, 42ft, and 7m Telescopes. But Jodrell Bank is also home to the e-MERLIN network, an array of seven radio telescopes across the UK. These includes those at Jodrell Bank, along with telescopes at Pickmere, Darnhall, Knockin, Defford and Cambridge.
Since then, the telescope has been upgraded several times and it remains one of the biggest and most powerful radio telescopes in the world, spending most of its time investigating cosmic phenomena which were undreamed of when it was conceived.
It was given a Heritage Grade I listing in 1988.
It is approximately 25m in diameter and was the first telescope of any type in the world to be controlled by a digital computer. In 1987 new aluminium panels were mounted on the original steel surface and have an RMS surface accuracy of around 1/3 mm.
In 2017 it was given a Heritage Grade I listing.
They use it to study emission from neutral atomic hydrogen in the Milky Way and nearby galaxies and to observe pulsars, which are rapidly rotating neutron stars.
