How is the universe put together? How is it built? And how does it actually work? How the Universe Works Series 8 shows the inner workings of our planet, the solar system, the galaxies and the universe itself.
In the first episode, if a massive asteroid collides with earth, it could end life on our planet as we know it. New discoveries and cutting-edge tech reveal just how close we are to apocalypse and what it would take for the world's leading space agencies to stop it.

This series traces the history of classic video games, featuring insights from the innovators who brought these worlds and characters to life. In the first episode, Space Invaders and Pac-Man lead an arcade craze, while Atari's cartridge system dominates home gaming until high-profile failure sparks a downfall.

On the second part of his journey through the dark ages Richard Rudgley continues into the age of the wandering peoples, the Volkerwanderung. These Northern people enjoyed a golden age unaffected by Rome and just 30 years after the Romans relinquished Britain, the 'Anglo-Saxons' made their move. The bedraggled legions are in retreat. Walls are pulled down. Mosaics shattered. And yet there never was a people called Anglo-Saxon. We look at the lasting influence of Saxon leaders like Alfred the Great, and his blue print for social justice.

The film examines the profound claim that most, if not all, of the degenerative diseases that afflict us can be controlled, or even reversed, by rejecting our present menu of animal-based and processed foods.
Despite the most advanced medical technology in the world, we are sicker than ever by nearly every measure. Cases of diabetes are exploding, especially amongst our younger population. About half of us are taking at least one prescription drug and major medical operations have become routine. Heart disease, cancer and stroke are the country's three leading causes of death, even though billions are spent each year to 'battle' these very conditions. Millions suffer from a host of other degenerative diseases. Could it be there's a single solution to all of these problems?

In the fall of 2016, an army of over 100,000 Iraqi soldiers and militiamen mobilize to liberate Mosul, Iraq's second largest city, from the clutches of the Islamic State. Ali Mula, an Iraqi journalist, joins this army of uneasy allies--including Sunnis, Shiites, Christians and Kurds--to find out if they can put aside their sectarian differences and finally free their country from the scourge of ISIS.
Along the way to Mosul, Ali encounters an unforgettable group of characters including a Sunni tribal leader who calls himself 'the Crocodile', a female militia leader avenging the death of her husband, a canny, Iranian-backed militia leader, a lawyer-turned-warrior, an elite band of ISIS killers, and refugees who survived the brutality of ISIS occupation. As he nears the end of his journey, Ali meets face-to-face with a die-hard ISIS prisoner who reveals the truth behind his nefarious organization.

What sort of alien civilizations might exist in the vastness of space? Terra is the fictional world imagined in Episode 4, a planet nine billion years old, twice as old as Earth. Old enough that a truly advanced intelligence could evolve. It was once a fertile world, now it is barren. But life can still thrive here in artificial domes. Over time, they've evolved not to need their bodies. They exist only as neural tissue. They never age, they never die. They're monitored and maintained by robots.
If alien civilizations are statistically so likely, why haven't astronomers found any sign of them? Where is everyone? Every time we look at an individual star, that's like dropping a bucket in the ocean. We're going to have to look at a lot of stars and to search through a lot of data until we find the clue that leads us to another civilization.
