Blue Dot

Professor Tim O’Brien celebrates 60 years of the Lovell Telescope, 50 years of pulsars and 40 years since the launch of the Voyager spacecraft. It was Voyager 1 that took a famous photograph in which the Earth, from a distance of 6 billion kilometres, is just a tiny dot. A photograph which inspired Dr Carl Sagan’s book, Pale Blue Dot, and after which we named our festival. Welcome to bluedot 2017!
