Professor Brian Cox tackles some of the most challenging and intriguing questions facing science. He looks back on a decade of discovery and towards the next space frontier.
Brian believes we are at the start of a new age of space travel, where space flight is on the verge of becoming routine. In this episode, he explores the latest science and takes a new look at his old films and asks: how far can we go in our exploration of the cosmos?

The white hole is a region of spacetime and that cannot be entered from the outside, although energy-matter, light and information can escape from it. In this sense, it is the reverse of a black hole. Einstein predicted strange cosmic phenomena known as white holes, but scientists have yet to prove they exist.
Today, astronomers race to find the clues that can unlock the secrets of white holes. They investigate the tiny black holes that hide in the most ancient parts of the universe to finally find the smoking gun.

The Sky at Night looks back at the last ten years of astronomy and ponders the most significant milestones and revelations. With the help of six distinguished astronomers, Chris and Maggie consider the state of astronomy in 2020 and wonder what new, exciting discoveries await us across the rest of the decade, as a host of new ground and space telescopes come online. Astronomer Royal Lord Martin Rees is among the guests to walk along the Astronomical Wall of Discovery in this one-hour special.

The incredible story of how Pluto has been propelled from an unremarkable ball of ice on the edge of the solar system to a world of unimaginable complexity - where some form of alien life might exist.
New discoveries from the edge of the solar system are transforming what is known about Pluto, thanks to the New Horizons space probe that took the first-ever close up images of the planet. Pluto was once thought to be geologically dead, but the pictures revealed it to be an active world of stunning complexity, with mountains carved from ice, a nitrogen glacier that appeared to be moving and a recently active volcano, with data sent back lead some scientists to speculate that there may even be life on Pluto today.

Astronomers are giving us astonishing news, visual proof of the reality of black holes. Stunning new findings are overturning conventional theories. The most common vision of black holes is that they are monstrous and mysterious bodies swallowing everything around them. However, the latest discoveries are drawing a link between black holes and the existence of life. A startling new picture is emerging. The existence of black holes is what made life on Earth possible.

Looking back on the major stories of the year - from the New Horizons mission to the most distant world we have ever visited to the release of the first-ever picture of a black hole. The team relive the highlights and uncover the latest developments.
