The film looks at the latest understanding of black holes, featuring an interview with Stephen Hawking. Black holes are one of the greatest mysteries in the universe. They behave in a way that is contrary to laws of physics and one has never actually been seen. However, the recent detection of gravitational waves, as predicted by Einstein, proves that black holes exist and provides a way to investigate their remarkable behaviour and properties.

By 2050, lunar settlers could be making oxygen, growing food and finding water in a bustling, self-sustaining settlement. See what life may be like on the Moon. The day before the 40th Anniversary of Apollo 11, NGC presents Living on the Moon. Man has always dreamed of living on the moon, and now a team of NASA scientists is proving that dream could be achieved in our lifetime. We take viewers inside Constellation, the space program's plan to establish a human outpost on the moon by 2020. Take a closer look at the plans underway, from upgraded space suits to housing modules and moon vehicles, and examine the challenges ahead, such as finding water, making oxygen, growing food and protecting residents from deadly radiation. Then, using 3-D animation, we'll visualize how the remarkable outpost will take shape.

An exploration of Earth's cosmic neighbourhood. Looking beyond the borders of our solar system, what's nearby in our galaxy? How do the other objects in our local area influence life on Earth? And, how did Earth's place in the galaxy make it the perfect place for the development of advanced life? Now that the Voyagers have visited the outer planets of the solar system they are heading for new adventures in places astronomers call the Oort Cloud, the heliopause, heliosheath and eventually they may encounter double stars and exoplanets, some of which may pay a visit to the solar system one day or explode showering us with radiation. If the Voyagers live so long they will experience the local fluff, local bubble and other parts of the habitable zone of the galaxy.

A variety of cosmic events have both helpful and harmful effects on life on Earth. From the beauty of the Aurora Borealis and rainbows to the dangers of UV radiation and cosmic rays, from the miracle of photosynthesis to the thrill of a meteor shower, this episode explores how the effects generated by the sun and other extra-solar sources can literally get under our skin, scramble our technology, make life possible and threaten our existence all at the same time

Low Earth Orbit, 120 miles above sea level, is where the majority of space exploration has occurred. This 1,100 mile band around Earth is where--for a cool $20 million--any private citizen can take the vacation of his or her life on the International Space Station. Commercial prospects for LEO are huge; but dangers lurk for any individual willing to travel here--radiation, cosmic rays, and space debris numbering in the thousands threaten any spacecraft travelling in orbit. It's the new frontier, or the final frontier...and the possibilities are endless if you are willing to travel to the edge of space exploration.

This documentary series explores the Three Mile Island Accident that occurred in Pennsylvania on March 28, 1979, suffering a partial meltdown of the reactor core on the same day. It also reveals how this accident unfolded in real time, its impact on the community and the personal account of the chief engineer and whistleblower, Richard Parks, who had the courage to speak out and avert a catastrophe for the East Coast.
This first episode explains how in 1979, a breakdown at the power plant causes confusion and the release of radiation. Fear spreads, as do suspicions that the authorities are hiding the truth.
