Today we’re rounding out our planetary tour with ice giants Uranus and Neptune. Both have small rocky cores, thick mantles of ammonia, water, and methane, and atmospheres that make them look greenish and blue. Uranus has a truly weird rotation and relatively dull weather, while Neptune has clouds and storms whipped by tremendous winds. Both have rings and moons, with Neptune’s Triton probably being a captured iceball that has active geology.
This is the epic story of the stars, and how discovering their tale has transformed our own understanding of the universe. Once we thought the sun and stars were gods and giants. Now we know, in a way, our instincts were right. The stars do all have their own characters, histories and role in the cosmos. Not least, they played a vital part in creating us. There are old, bloated red giants, capable of gobbling up planets in their orbit; explosive deaths - supernovae - that forge the building blocks of life; and black holes, the most mysterious stellar tombstones. And, of course, stars in their prime, like our own sun. Leading astronomers reveal how the grandest drama on tonight is the one playing above our heads.

Eight days, three hours, 18 minutes, 35 seconds. That is the total duration of the most important and celebrated space mission ever flown - Apollo 11 - when humans first set foot on the moon. It was a journey that changed the way we think about our place in the universe. But we only saw a fraction of what happened - a handful of iconic stills and a few precious hours of movie footage. Now it is time to discover the full story. Previously classified cockpit audio, recorded by the astronauts themselves, gives a unique insight into their fears and excitement as they undertake the mission. And dramatic reconstruction brings those recordings to life, recreating the crucial scenes that were never filmed - the exhilarating launch, the first sight of the moon, the dramatic touchdown and nail-biting journey home. Original archive footage from the Apollo programme is combined with newly shot film and cinematic CGI to create the ultimate documentary of the ultimate human adventure.
