BBC Four - Journeys in Time and Space, Invisible Universe

Chris Riley searches for dark matter, and Dr Kathy Sykes talks to Jocelyn Bell-Burnell.

Chris Riley goes in search of elusive dark matter, and Dr Kathy Sykes talks to Jocelyn Bell-Burnell, the legendary astronomer who discovered pulsars while doing her doctorate.

Despite fantastic advances in technology, over 90% of our Universe appears to be missing.  In this second programme of the series Chris Riley goes in search of this elusive so-called 'dark matter', a trail which leads him to an unlikely location - Europe's deepest mine, 1000m beneath the earth's surface.  Also we meet Jocelyn Bell-Burnell, the legendary astronomer who discovered a very strange body in the late 1960s - the 'pulsar', a star so dense that a single teaspoon could weigh a hundred million tons.  And we explore our nearest neighbour, the Moon, and find out why its surface could be more precious than gold dust.
