A spectacular journey into the depths of space: In August 1977, NASA launches one of its most daring missions in space flights. The Deep Space orbiters Voyager 1 and Voyager 2 are shot into space. The task of the two orbiters: exploring the outer gas planets in our solar system. More than 30 years later, the two orbiters have traveled a distance of 15 billion miles and still send unique data to Earth. Countless recordings of these orbiters still serve as the only footage of the two planets Uranus and Neptune, and their moons. After more than 30 years of flight Voyager 1 is the farthest from Earth object that mankind has ever created. THE VOYAGER SHOW: ACROSS THE UNIVERSE demonstrates all the technical, historical and astronomical details of the fascinating Voyager missions that continue to this day.
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.

We’ve covered a lot of incredible stuff, but this week we’re talking about the weirdest objects in space: BLACK HOLES. Stellar mass black holes form when a very massive star dies, and its core collapses. The core has to be more than about 2.8 times the Sun’s mass to form a black hole. Black holes come in different sizes, but for all of them, the escape velocity is greater than the speed of light, so nothing can escape, not matter or light. They don’t wander the Universe gobbling everything down around them; their gravity is only really intense very close to them. Tides near a stellar mass black hole will spaghettify you, and time slows down when you get near a black hole — not that this helps much if you’re falling in.
Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system. The Kuiper Belt is a donut shape aligned with the plane of the solar system; the scattered disk is more eccentric and is the source of short period comets; and the Oort Cloud which surrounds the solar system out to great distances is the source of long-period comets. These bodies all probably formed closer into the Sun, and got flung out to the solar system’s suburbs by gravitational interactions with the outer planets.
