The new Square Kilometre Array telescope (SKA) is set to be the world’s largest radio telescope, and 50 times more sensitive than its predecessor. It will cost £1.3bn, and is likely to be built in Australia or South Africa, but will have its headquarters firmly planted at Jodrell Bank, Cheshire.
The SKA telescope will have a receiving area of one square kilometre, meaning it could pick up a mobile phone signal on Neptune. But why do we need such a huge international piece of equipment?
