Europa - an icy moon of Jupiter 485 million miles away from Earth - may be our best hope for finding alien life in our solar system. Everywhere we find water on Earth, we find life. What does this mean for the search for life beyond Earth? Scientists believe that on Europa there is a liquid ocean buried beneath its icy crust. To find out if this alien ocean holds life, well need to get there, penetrate the ice shell, and navigate in an alien sea. In this episode of Explorer, well plunge headlong into the challenges of discovery on an alien world. Well meet the scientists, adventurers, and engineers who are determined to launch a mission to Europa - and follow them through the challenges, frustrations, and triumphs that come with planning a distant mission to an alien world. Through high-end CGI and quests to the edge of our planet, well go on a journey to and alien moon called Europa. To answer the basic question: Are we alone in the universe?

In 1972, the crew of Apollo 17 captured the iconic 'Blue Marble': the first photograph ever taken by an astronaut of the entire Earth. This photo had a profound effect on our perception of ourselves. Since then, Nasa has taken millions more. In this epic, powerful and revelatory documentary, a new generation of astronauts, including Tim Peake, use those images of the Earth from space to reveal the astonishing transformation humanity has wrought in the 45 years since 'Blue Marble'. Together, the astronauts provide an armchair tour of the change they've witnessed from orbit, as humankind etches our presence on the planet. Using stunning time-lapse sequences, the programme reveals how we are reshaping our world, for better and for worse: from the sprawling megacities of China to vast desert farms in the Middle East and from the melting snowcap of Kilimanjaro to giant solar arrays in Nevada.

Across the Milky Way, galaxies are going dark, and scientists don't know why the stars are losing their shine; astronomers race against time to uncover the truth behind how galaxies are born and how they die before all of the lights go out.

Almost everything we know today about the beautiful giant ringed planet comes from Cassini, the NASA mission that launched in 1997 and arrived at Saturn in 2004. Since then, the space probe has been beaming home miraculous images and scientific data, revealing countless wonders about the planet, its rings and 62 moons - including some that could harbor life. As the mission approaches its final days in 2017, it attempts one last set of daring maneuvers - diving between the innermost ring and the top of Saturn's atmosphere. Aiming to skim less than 2000 miles above the cloud tops, no spacecraft has ever gone so close to Saturn, and hopes are high for incredible observations that could solve major mysteries about the planet's core. But such a daring maneuver comes with many risks and is no slam dunk. In fact, slamming into rocks in the rings is a real possibility. Join NASA engineers for the tense and triumphant moments as they find out if their bold re-programming has worked, and discover the wonders that Cassini has revealed over the years.
