Building the Universe
How do you build a universe? Adam Hart-Davis is 100 metres underground with the team hoping to blast their way back to the Big Bang in the world's largest experiment. They are on the trail of tiny particles not seen since space and time began. There is also the story of Prof. Carlos Frenk who has spent decades attempting to make universes in his computer - but has only recently got the recipe right. And there is a team from Scotland who make stomach-churning anti-gravity flights in an attempt to find out how the planets were formed.

Seeing the Universe
How far out into space and back into time can we see? Adam Hart-Davis travels across Chile's Atacama desert to the world's largest telescope to discover how this massive machine is revealing incredible new sights from across the universe. Meanwhile, astronomer and engineer Dr Maggie Aderin visits the strange telescope in Tuscany that will soon reveal the cosmos using gravity waves - predicted by Einstein, but until now too weak to detect. She also joins the team at the Hubble Space Telescope who produce the most famous images of space by mixing art and science.

Other Worlds
Is there another Earth? Adam Hart-Davis is on the summit of La Palma in the Canary Islands, searching for planets around other suns. He discovers how it is possible to find planets too small to see, and tells the story of how the first ever planet outside our solar system was found - an event that rocked the world of astronomy. Janet Sumner visits the Virtual Planetary Laboratory, where they invent inhabited planets so that astronomers know what to look for.
