50 years on from the event, environmentalist Steve Backshall retraces a young Prince Charles' Arctic adventure and uncovers dramatic changes to our planet alongside an urgent need for action.

Through interspersed conversation and prose, this experimental documentary follows a poet and a neuroscientist as they explore the definition of love, what it means, and why it matters.

Pro-intelligent design scholars and scientists are often chastised, fired or denied tenured positions by those who believe in Darwin's theory of evolution.

A team of international skiers embark on a two-week glacier traverse connecting two remote research stations in Kazakhstan. The Tien Shan's 4000+ meter peaks host an active scientific community, leveraging the rare environmental conditions for groundbreaking research. Established during the Soviet Union's occupation, the high-altitude research stations here are home to some of the longest-standing glacier and cosmic radiation experiments in the world - and are surrounded by deadly alpine terrain.

In this two-part Channel 4 series, Professor Richard Dawkins challenges what he describes as 'a process of non-thinking called faith'. He describes his astonishment that, at the start of the 21st century, religious faith is gaining ground in the face of rational, scientific truth. Science, based on scepticism, investigation and evidence, must continuously test its own concepts and claims. Faith, by definition, defies evidence: it is untested and unshakeable, and is therefore in direct contradiction with science. In addition, though religions preach morality, peace and hope, in fact, says Dawkins, they bring intolerance, violence and destruction. The growth of extreme fundamentalism in so many religions across the world not only endangers humanity but, he argues, is in conflict with the trend over thousands of years of history for humanity to progress to become more enlightened and more tolerant.

A team of international scientists attempt to document the first-ever image of a black hole.

A mother embarks on a journey of acceptance and joy while supporting her child's gender transition in this heartfelt portrayal of single parenting and navigating the complexities surrounding gender and consent.

It all started with a simple question: Is it possible to travel to the oldest and newest places on Earth? YouTuber, author and filmmaker Joe Scott looked into it, and it turned into the trip of a lifetime. It's a journey across 4 billion years of geologic history that explores the past and present of our remarkable planet, the absurd immensity of deep time, and our tiny but important place in it.

United by the same dream, Yves Fagniart and Olivier Larrey, watercolorist and wildlife photographer respectively, set up home in a shack just a few square meters square, in the middle of the no-man's-land between Finland and Russia. Their aim: to document the intimate life of a pack of wolves, presumed to frequent this frozen peat bog landscape.

We have all dreamed of going where no man has gone before but that time is here and now. We are on the very edge of a new era in humanity. Within our lifetime, mankind will not only be journeying to other planets, we will be inhabiting them. Our ultra-high technology robots are even now walking upon the surface of Mars, sending back information and preparing the ground for our arrival. This is not science fiction, we are living the future now.
