NASA is on a mission to send humans to Mars within just 15 years, but to reach this next frontier of space exploration, experts must discover new technology and cutting-edge science that protects astronauts from the Red Planet's deadliest killers.

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.

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.

A stellar explosion, the supernova is the sensational death of a star. It can shine as bright as 100 billion Suns and radiate as much energy as the Sun would emit over 10 billion years. Jets of high-energy light and matter are propelled into space and can cause massive Gamma Ray Bursts and emit intense X-ray radiation for thousands of years. Astronomers believe that this process creates the very building blocks of planets, people and plants. Meet the world's leading Supernova hunters, and take a look at recorded supernovas throughout history.

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.

For all of human history, the Sun, our home star, has measured our days and our seasons while fueling all life on Earth. Yet it remains an enigma. NASA's Parker Probe Plus is on a mission to change that, flying through dangerous radiation to become the closest spaceship to orbit our Sun.
It's a journey to the center of our solar system, a mission to gather information about the most critical celestial body in the sky, our star.
