Black holes! From Stephen Hawking to Interstellar, black holes are mammoths in the world of science AND sci-fi. But what exactly IS a black hole? Do events happen inside black holes? Are black holes really a hole? Are black holes really black?! Join Gabe on this week’s episode of PBS Space Time as he debunks popular black hole misconceptions, and rethinks what the term, ‘black hole’, even means. Thought you knew what a black hole was? Think again!

Ideas about time and space are explored in the changes that constellations undergo over time, the redshift and blue shift measured in interstellar objects, time dilation in Albert Einstein's theory of relativity, the designs of both Leonardo da Vinci and spacecraft that could travel near light speed, time travel and its hypothetical effects on human history, the origins of the Solar System, the history of life, and the immensity of space. In Cosmos Update, the idea of faster-than-light travel by wormholes (researched by Kip Thorne and shown in Sagan’s novel Contact) is discussed.
Before moving on from Jupiter to Saturn, we’re going to linger for a moment on Jupiter’s moons. There are 67 known moons, and 4 huge ones that we want to explore in greater detail. Ganymede is the largest - larger, in fact, than any other moon in the solar system and the planet Mercury! Callisto, orbiting the farthest out, is smaller but quite similar to Ganymede in many ways. Io, meanwhile, is most noteworthy for its tremendous volcanic activity. There’s also water on Ganymede and Europa!
In August 2018 NASA launched the first ever mission to a star. A historic quest to explore the last great frontier of our solar system - the sun. This will be the fastest man made object ever created. A spacecraft that will travel 450,000 miles per hour. It's ground breaking mission, to fly into the 'atmosphere' of our star and revolutionize our understanding of it. This documentary will celebrate this world changing event. Exploring the amazing science of our sun and going behind the scenes of the NASA mission to reach it. Timed to coincide with the arrival of the probe into the sun's atmosphere (Nov 2018) and the huge media spike this will create, this documentary will celebrate a key moment in human history, humanities first attempt to touch the Sun.

Covers 1964-1968, four heady, dangerous years in the history of the space race, focusing on the events surrounding the Apollo 1 and Apollo 8 missions. As Americans moved through the 60s and reflect on the challenges ahead, many begin to wonder: What exactly is it going to take to beat the Soviets to the moon?
This first episode begins in 1957 and tracks the early years of the space race as the United States struggles to catch up with the Soviet Union. The episode reveals breathtaking failures and successes of the nascent American space program and demonstrates the stakes and costs of reaching the moon.
