Einstein, Oppenheimer, and other physicists and astronomers wrestled with the concept of Black Holes. With relentlessly powerful gravitational pull, black holes suck in anything that comes near them, but do they? As the study of black holes progresses, science finds more mysteries than solutions.

Black holes are the most enigmatic and exotic objects in the universe. They’re also the most powerful; with gravity so strong it can trap light. And they’re destructive, swallowing entire planets, even giant stars. Anything that falls into them vanishes…gone forever. Now, astrophysicists are realizing that black holes may be essential to how our universe evolved—their influence possibly leading to life on Earth and, ultimately, us. In this two-hour special, astrophysicist and author Janna Levin takes viewers on a journey to the frontiers of black hole science. Along the way, we meet leading astronomers and physicists on the verge of finding new answers to provocative questions about these shadowy monsters: Where do they come from? What’s inside? What happens if you fall into one? And what can they tell us about the nature of space, time, and gravity?

To land a human being on another celestial body will be the first step to living beyond our planet. The breathless pace and daring of the Apollo program sees NASA master previously unimagined tasks in the attempt to achieve the most incredible accomplishment in the history of human endeavor. From the ashes of tragedy on Apollo 1 emerges a determination that puts Apollo 8 in orbit around the Moon ahead of schedule. Apollo 9 and 10 each break bold new ground and pave the way for something few dared to believe was possible. When Neil Armstrong and Buzz Aldrin walk on the Moon and return safely to earth, the whole planet throws them a party.
