The centre of our galaxy is home to an invisible monster of unimaginable power – a supermassive black hole named Sagittarius A star, with four million times the mass of the Sun. Recent astronomical breakthroughs have confirmed not only that black holes like Sagittarius A star exist, but that these bizarre invisible objects may be the ultimate galactic protagonists.
Stunning CGI takes us back to witness the fiery origins of our galaxy’s black hole 13.6 billion years ago, when the early universe was home to colossal blue stars, and when they ran out of fuel, they collapsed under their own enormous mass, crushing down into an object so small and so dense it punched a hole in the fabric of the universe. Over billions of years, Sagittarius A star feasted on nearby gas, stars, and through cataclysmic mergers with other black holes. A breakthrough discovery by Nasa’s Fermi gamma-ray telescope has shown that our black hole had the power to sculpt the entire galaxy, creating vast bubbles of gas above and below our galaxy and even protecting stars systems as ours.
In a mind-bending conclusion, Brian Cox reveals how our modern understanding of black holes is challenging our concepts of reality to the breaking point. In trying to understand the fate of objects that fall into Sagittarius A star, scientists have come to a stunning conclusion: space and time, concepts so foundational to how we experience the world around us, are not as fundamental as we once thought.

The film documents the English heavy metal band Black Sabbath's final show of their farewell concert tour, The End Tour. The performance was held at the Genting Arena in Birmingham, England, hometown of the band's founding members: vocalist Ozzy Osbourne, guitarist Tony Iommi, bassist Geezer Butler, and drummer Bill Ward. Osbourne, Iommi, and Butler performed this final concert with session drummer Tommy Clufetos in place of Ward, as well as Adam Wakeman on keyboards and guitar.
The concert opens with a performance of the song 'Black Sabbath'. The film goes on to show the band performing 'Fairies Wear Boots', 'Under the Sun/Every Day Comes and Goes', 'Into the Void', 'Snowblind', 'War Pigs', 'Hand of Doom', 'Iron Man', and 'Children of the Grave'; at the end of the setlist, the band performs the song 'Paranoid' as an encore.
Interspersed with the final concert are interviews with Osbourne, Iommi, and Butler, in which they talk about their careers and past drug addictions. Additionally, Iommi's 2012 lymphoma diagnosis, which impacted the band's 2012–14 reunion tour and the recording of their 2013 album 13, is discussed. The film also features footage of 'The Angelic Sessions'—the band's final studio recordings, which took place in the days following the final show. Of these recordings, the film shows Osbourne, Iommi, and Butler performing 'The Wizard', 'Wicked World', and 'Changes'.

Scientists investigate the way the Sun builds its power -- through fusion -- hoping to find a way to use fusion as a less dangerous and less radioactive waste-producing path to energy than fission. But there are some major difficulties along the way. Fusion really is the perfect way to make energy. We have millions of years worth of fuel. It produces no long-lived radioactive waste. If we can solve the engineering challenges, energy will become cheaper, more available for everybody.

Could nuclear fusion hold the answers to the energy crisis? It is the process that has forged all matter in the universe. It lights the stars and it is what transformed the lighter atoms that formed in the Big Bang into heavier atoms. In Can We Make a Star on Earth?, Brian Cox peers beyond the glare of our Sun to reveal the hidden forces that provide its power. He discovers how this fusion energy has kept our closest star burning for five billion years. Brian believes humanity must build a star on Earth to ensure survival. Will scientists be able to harness fusion power and achieve abundant, cheap, clean energy?

The film captures the global challenge to lead the clean energy future by profiling U.S. and Chinese workers and business leaders who are racing to make crucial breakthroughs in the field. Catching the Sun debunks a false dilemma that clean energy requires sacrificing economic prosperity.
Through the stories of an unemployed American worker, a Tea Party activist, and a Chinese solar entrepreneur, we will explore the global energy transition from the perspective of workers and entrepreneurs building solutions to income inequality and climate change with their own hands. Their successes and failures speak to one of the biggest questions of our time: will the countries actually be able to build a clean energy economy?

Sunset over the plains of Kenya's Maasai Mara, one of Africa's most protected wild spaces. And home to the fastest land animal on Earth, the cheetah. These agile cats have always been thought of as daylight hunters. They target prey from more than a kilometre away and chase it down at over 100 kilometres an hour. In one of these plains, two cheetah brothers attempt a high-speed night hunt with a gang of powerful hyenas on their trail.
