Located in an almost inaccessible chamber deep in a South African cave, the site required recruiting a special team of experts slender enough to wriggle down a vertical, pitch-dark, seven-inch-wide passage. Most fossil discoveries of human relatives consist of just a handful of bones. But down in this hidden chamber, the team uncovered an unprecedented trove—so far, over 1,500 bones—with the potential to rewrite the story of our origins". They may help fill in a crucial gap in the fossil record and tell us how Homo, the first member of the human family, emerged from ape-like ancestors like the famous Lucy. But how did hundreds of bones end up in the remote chamber? The experts are considering every mind-boggling possibility. Join us on the treacherous descent into this cave of spectacular and enigmatic finds, and discover their startling implications for the saga of what made us human.

In this 2-part special, Professor Brian Cox tackles the biggest story of them all, the story of our Universe. In the first episode, Creation, Brian probes our moment of creation. How did our Universe come into existence? Was there a time before the Big Bang? Do our laws of physics inexorably lead to the existence of us?

The series heads to the very frontiers of space and science to produce the definitive history of science fiction. What if our creations turn against us? The idea of creating life has fascinated society since the earliest days of science fiction. Robots transports viewers from the first steps of Frankenstein’s monster to the threat provided by the Terminator and the world of Cyberspace. Find out how Rutger Hauer created one of the greatest speeches in all of science fiction for Blade Runner. Discover from Kenny Baker the challenge of acting in Star Wars while inside the body of R2D2, and learn how Anthony Daniels was drawn to the role of C-3PO by concept art modeled closely on the robot from the silent classic Metropolis. The creators of the original Robocop describe how its hidden depths have given it enduring appeal and William Gibson reveals the origins of his seminal novel Neuromancer. From HAL in 2001: A Space Odyssey to the Cylons of the reimagined Battlestar Galactica and the world of The Matrix, this is a journey that asks – what does it mean to be human?

Take a look at the issues that will change the way we live our lives in the future. Hannah Fry delves into the data we have today to provide an evidence-based vision of tomorrow. With the help of science experts Hannah tries to discover whether we could ever live forever or if there will ever be a cure for cancer. She finds out how research into the human brain may one day help with mental health, and if it is possible to ever ditch fossil fuels. Hannah and her guests also discover the future of transport - and when, if ever, we really will see flying cars. She discovers whether a robot will take your job or if, as some believe, we will all one day actually become cyborgs. The programme predicts what the weather will be like and discovers if we are on the verge of another mass extinction. Hannah's tenth prediction is something she - and Horizon - are confident will definitely happen, and that is to expect the unexpected!

Is there anyone out there? Astronomers have been pointing their radio telescopes at the skies for decades trying to pick up alien signals, so far without success. But now there's a new way of looking for aliens. Hitch a ride with Dr Graham Philips as he joins astronomers trawling through the galaxy looking for signs of extra-terrestrial intelligence.

Experts suspect that the dinosaurs were wiped out after a city-sized asteroid smashed into the Gulf of Mexico causing a huge crater. But until now, they haven't had any proof. In a world first, evolutionary biologist Ben Garrod joins a multi-million pound drilling expedition into the exact spot the asteroid hit to get hard evidence of the link. The team overcomes huge obstacles as it attempts to drill 1,500 metres beneath sea level to pull up rock from the Chicxulub crater. Meanwhile, paleopathologist Professor Alice Roberts travels the globe meeting top scientists and gaining exclusive access to a mass fossil graveyard in New Jersey - believed to date from the same time the asteroid hit. Alice also treks by horseback across the remote plains of Patagonia, to see if the effects of the asteroid impact could have wiped out dinosaurs across the world - almost immediately.
