What would you tell an alien civilisation about life on Earth?
In 1977, a once-in-a-lifetime alignment of the planets gave Nasa the chance to launch spacecraft that could explore the outer edges of our solar system and beyond. Onboard was a gold-plated record carrying sounds, music and pictures of Earth, designed as a message for any aliens that might be out there. As the Voyager 1 probe reaches the milestone of one light-day from Earth, we explore the extraordinary story of the Golden Record. We look at how an alien civilisation might decode it, what its message reveals about humanity and how its map could point extraterrestrials back to our planet.
