Look up at the night sky, and you see countless shining stars. Our galaxy has 100 billion of them. Astronomers are now hunting for clues that will reveal "the first star" that transformed the ancient universe and led to the creation of everything that followed: galaxies, planets and life itself.

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.

The hunt for aliens is on! After a distinguished career in cosmology Professor Martin Rees, the astronomer royal, has taken up the search for extra-terrestrials. Looking for aliens is no longer science fiction - it is a question that's engaging some of the greatest minds in science. As our knowledge of the universe has increased, we're getting closer to answers. Many scientists now think we live in galaxy with a billion Earth-like planets, many of which may be teeming with life. But what kind of life? Has anything evolved into beings we could communicate with? This film gets inside the minds of the scientists considering one of the most exciting and profound questions we can ask - are we alone in the universe? Professor Rees thinks we may have our idea of what an alien is like all wrong. If he's right, it's not organic extra-terrestrials we should look for, it's machines.
