PBS' premier science series helps viewers of all ages explore the science behind the headlines. Along the way, NOVA demystifies science and technology, and highlights the people involved in scientific pursuits.

Horizon tells amazing science stories, unravels mysteries and reveals worlds you've never seen before.

Over two extraordinary years, National Geographic Explorer Bertie Gregory discovered never-before-filmed secret traditions, surprising intelligence and close-knit societies of penguins. This astonishing series reveals they are more like us than we ever dreamed, from their powerful friendships to the courageous risk-takers using ingenuity and innovation in some of the world's most extreme places.

The Hundred Years’ war between England and France gave us the victories of Crecy and Agincourt, and made the reputations of Edward III and Henry V. It gave France a national heroine in Joan of Arc. But, even now, the jury is out as to its causes and outcome. Was it the final swansong of a redundant knightly class whose only reason for being was to fight? Was it a battle over ever more important territory to the emerging economies of England and France? Or was it the painful birth of two distinct national identities, forged through their long and violent divorce? Dr Janina Ramirez guides us through the stories of kings, great knights, bloody battles and cultural triumphs of this momentous conflict.

After one of the hottest years on record, Sir David Attenborough looks at the science of climate change and potential solutions to this global threat. Interviews with some of the world’s leading climate scientists explore recent extreme weather conditions such as unprecedented storms and catastrophic wildfires. They also reveal what dangerous levels of climate change could mean for both human populations and the natural world in the future.

200 babies are brought together to take part in an ambitious scientific study exploring how the incredible changes that happen in the first two years of life make us who we are.

Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?

BBC Horizon follows the ups and downs of an outstanding story in particle physics. In June 2015, teams at CERN started running the large hadron collider at the highest energy ever. Rumours quickly emerged that they were on the brink of a huge discovery. An enigmatic bump in some data suggested a first glimpse of a brand new particle that could change our understanding of how the universe works.
