This is the story of how our solar system will be transformed by the aging sun before coming to a spectacular end in about eight billion years. Astronomers can peer into the far future to predict how it will happen by analysing distant galaxies, stars and even planets in their final moments. In this film, Horizon brings these predictions to life in a peaceful midwestern town that has a giant scale model of the solar system spread out all over the city. As it ages, the sun will bloat into a red giant star, swallowing planets... as well as half the town. The fate of the Earth itself hangs in the balance. How will the solar system end?
The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History.
Of all life on Earth, we're the only ones with the smarts to leave our planet. How did our planet make us so intelligent? Astronaut host – Leland Melvin.
