THE UNIVERSE The biggest character of them all…the universe itself. Infinite in scale, and eternal, we tackle it's biggest mysteries – where did it all come from and how did it begin? The answers lie at the Big Bang. STARS There are more stars in the universe than grains of sand on every planet in the solar system. We'll reveal how our Sun was created from the chaos of another star's death, and unravel how it went from deadly giant to the life-giving force it is today. GALAXIES We'll reveal the surprising story of our Milky Way. The dramatic moments that created its enigmatic shape, the inevitable collision that will end its life, and why life can only exist in tiny regions of the fraction of galaxies like our own. ALIEN WORLDS We now know there are thousands of alien worlds; planets rich with diamonds, some orbiting multiple stars, each stranger than the last. These alien characters tell an extraordinary tale – and allow us to start answering the big question: Are we alone? BLACK HOLES Black holes are the universe's most enigmatic inhabitants; the life-giving seeds around which galaxies grow, but also destroyers of space and time. We discover the story of the black hole at the heart of our galaxy.
