On a dry lakebed in Nevada, a group of friends build the first scale model of the solar system with complete planetary orbits: a true illustration of our place in the universe.
In August 1977, the Big Ear Radio-telescope in Ohio received a strange signal from the Sagittarius constellation while searching for intelligent extra-terrestrial life. It had a duration of 72 seconds and an intensity 30 times higher than usual. Named the WAW signal (as an engineer wrote ‘WOW’ on the data as it came in!), it is still being considered as one of the best examples of having being sent by intelligent extraterrestrial life. But, nothing has revolutionised the search of extra-terrestrial intelligent life as much as the recent discovery by the Kepler Satellite, of thousands of Earth-like planets where life could be possible. Join the debate with this stunning one-hour documentary from 2015, as we ask Is Anybody Out There?

Mercury is a deadly world, facing attacks from the sun, comets, and other planets, and even though it's the smallest planet in the solar system, it has a dangerous secret a dangerous secret that might one day threaten life on Earth.
A look at the continuing evolution of the cosmos. What our existence tells us about the universe and how complicated it is. Why are things the way that they are? The spacecraft Artemis initiates launch sequence and begins its 4.7 light year journey to Minerva B - an Earth-like exoplanet.
This episode documents how gravity has an effect across the universe, and how the relatively weak force creates an orbit. We also see how a neutron star's gravity works. Finally, there is a look back at how research on gravity has enabled us to better understand the cosmos.
