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.
The idea of intelligence is explored in the concepts of computers (using bits as their basic units of information), whales (in their songs and their disruptions by human activities), DNA, the human brain (the evolution of the brain stem, frontal lobes, neurons, cerebral hemispheres, and corpus callosum under the Triune Brain Model), and man-made structures for collective intelligence (cities, libraries, books, computers, and satellites). The episode ends with speculation on alien intelligence and the information conveyed on the Voyager Golden Record.
The most amazing images of the universe captured by the space telescope, and a look at plans to launch a new and more advanced satellite in 2018. In this updated version of "Hubble's Amazing Journey” we reveal some of Hubble's latest observations: It has produced some of the most awe-inspiring images ever taken of the universe. But what is often forgotten about the Hubble Space Telescope is that after its launch 25 years ago it was originally labelled an embarrassing and expensive flop.

The Hayabusa2 spacecraft has just completed one of the most intricate procedures in space exploration. The first mission to deliver rovers onto an asteroid has now descended to its surface for a sample, before returning back to Earth in 2020.
Shocking new evidence has convinced some of the world's greatest physicists that the universe is a hologram. Using cutting-edge technology, they investigate the secrets of black holes and space-time to build the case for this game-changing discovery.
