Brian Cox and Robin Ince are joined by a dazzling panel of sun worshippers from actor, comedian and musician Tim Minchin to solar scientist Professor Lucie Green and biologist Professor Steve Jones. They look at how the evolution of life was only possible because of our position relative to the sun and its possibly unique behaviour, and how rare that situation might be across the rest of the universe. They also look at how the sun makes you feel and its vital importance to all creatures, especially snails.
