The worlds that surround our planet are all made of rock, but there the similarity ends. Some have a beating geological heart, others are frozen in time. Professor Brian Cox travels to the tallest mountain on Earth, the volcano Mauna Kea on Hawaii, to show how something as basic as a planet's size can make the difference between life and death.

Nasa intends to send astronauts to Mars. To succeed, crew members will have to overcome unprecedented, life-threatening challenges, and while many of these hazards are physical, the most elusive are psychological. Throughout the expected three-year absence, crew members won't be able to communicate with Earth in real time due to the immense distance. The psychological impact of this level of disconnectedness and isolation - both from mission control and loved ones - is impossible to predict and endangers the mission itself. Directed to mitigate this threat is Dr Al Holland, a Nasa psychologist whose job is to keep astronauts mentally stable in space. The Longest Goodbye follows Holland, rookie astronauts Kayla Barron and Matthias Maurer and former astronaut Cady Coleman, among others, as they grapple with the tension between their dream of reaching new frontiers and the basic human need to stay connected to home.

It’s a golden age for planet hunters: NASA's Kepler mission has identified more than 3,500 potential planets orbiting stars beyond our Sun. Some of them, like a planet called Kepler-22b, might even be able to harbor life. How did we come upon this distant planet? Combining startling animation with input from expert astrophysicists and astrobiologists, “Alien Planets Revealed” takes viewers on a journey along with the Kepler telescope. How does the telescope look for planets? How many of these planets are like our Earth? Will any of these planets be suitable for life as we know it? Bringing the creative power of veteran animators together with the latest discoveries in planet-hunting, “Alien Planets Revealed” shows the successes of the Kepler mission, taking us to planets beyond our solar system and providing a glimpse of creatures we might one day encounter.
