In the middle of the Australian outback, an hour’s drive from the nearest homestead, scientists are building the world’s largest telescope. There is no internet, no mobiles phones, no wifi - and the few people who work at the site live behind double doors in an office that has been wrapped in metal sheets to act as a Faraday cage. Veronika Meduna visits the Square Kilometre Array site to find out how this radio-quiet zone will allow the dishes and antennae to tune into the faintest radio hum from the universe in search of alien life and the cosmic dawn.
