The Pale Blue Dot

In February 1990, the Nasa space probe Voyager took a famous photo of Earth as it left the Solar System. Seen from six billion kilometres away, our planet appears as a mere dot lit up by the Sun, and the image is credited with giving humanity a sense of our small place in the Universe. Darryll Morris speaks to Nasa planetary scientist, Candice Hansen, who worked on the Voyager programme. The programme is a Made-In-Manchester Production.
