In February 1990, 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, giving a sense of humanity's small place in the universe.
In 2020, Darryl Morris spoke to Nasa planetary scientist Candice Hansen, who worked on the Voyager programme. A Made in Manchester production for BBC World Service.
