We used to think that Earth was at the centre of the universe, but now we know we're not even at the centre of our own galaxy. Countless wonders exist between where earth is situated and the massive black hole at the galactic centre of our galaxy. Within the Milky Way can be found the debris of old, dying stars fuelling the birth of new stars and at the galactic centre hypervelocity stars get catapulted clear beyond the Milky Way's outer rim at unimaginable speeds. Come along for a guided tour of 100,000 light-year-wide family of stars and stellar phenomena we call The Milky Way.

Find out what is being done to prevent the end of the world from threats from outer space such as comets and asteroids. Also discussed are apocalyptic scenarios.

Freeman's quest to understand what makes a rebellion successful brings him face-to-face with exiles, whistle blowers, hackers and movement leaders. From Berlin to Bolivia to the United States, he'll see the courage, dedication, hard work and hope that it takes to try to change the world.

The series Warrior Graveyard uncovers some extraordinary warrior skeletons from history. Archaeologists and forensic scientists use remains to tell the story of famous warriors of the past and unleash the full force of modern forensics upon them: battle scars, bone deformations and recoverable scraps of DNA will all be tested and explored. CGI and drama will then bring them dramatically to life, revealing a revolutionary new picture of how these warriors lived - and died.
An archaeological and forensic examination of six crusaders' bones brings to life the 1179 Battle of Jacob's Ford, revealing the wounds that killed the warriors in the Holy Land. With every sword slash comes an insight into an historic day. Excavations along the Israel/ Jordan border are unearthing skeletons and rewriting the history of the First Crusade. The site at Jacob's Ford is the only known Crusader battle site with complete skeletons. To secure the road between Akkon and Damascus, King Baldwin IV of Jerusalem had a mighty castle built at the Jacob's Ford of the Jordan River in October 1178. The fortress was a thorn in the side of Sultan Saladin, so he had it stormed a year later, before it was completed.
Excavations have been taking place on the site of the legendary crusader castle since the early 1990s. Archaeologists and forensic experts have examined the remains of six fallen crusaders and uncovered fascinating details about the Battle of Chastellet. The programme has secured access to the excavation and remains of some of the 80 Crusader Knights and 750 foot soldiers stationed at the fort when it was attacked and its Crusaders massacred by Saladin's army in 1179, in the battle that changed the course of history in the Middle East.

Black Holes are one of the most destructive forces in the universe, capable of tearing a planet apart and swallowing an entire star. Yet scientists now believe they could hold the key to answering the ultimate question - what was there before the Big Bang? The trouble is that researching them is next to impossible. Black holes are by definition invisible and there's no scientific theory able to explain them. Meet the astronomers attempting to image a black hole for the very first time and the theoretical physicists getting ever closer to unlocking their mysteries. It's a story that takes us into the heart of a black hole and to the very edge of what we think we know about the universe.

There is an extraordinary range of temperatures in the universe. This program examines the extreme lower temperature range, the temperature we live in and below, explaining how cold is essential for the formation of habitats suitable for life. Explore icy planets and moons, discover the role of cold in the Universe, and learn about the importance of ice to the development of habitable worlds.
