“Can lightning strike upwards?” and “What is the wettest place in the world?” BBC Click Radio presenter Gareth Mitchell answers life's big questions
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?
