In search of stardust

Bbc World Service
About this episode

Norwegian jazz musician Jon Larsen was having breakfast one clear spring morning when he noticed a tiny black speck land on his clean, white table. With no wind, birds or planes in sight, he wondered if it fell from space.

Dust from space is not as fanciful as it sounds. Billions of microscopic meteorites, dating back to the birth of our solar system, fall onto Earth every year. But they are so tiny, hidden among the copious dust of everyday life, that scientists believe they are impossible to find outside ultra clean environments like Antarctica.

But this doesn’t deter Jon, who, against the advice of all experts, decides he is going to be the first person to find an urban micrometeorite.

He takes presenter Caroline Steel and planetary scientist Dr Matthew Genge up onto some roofs, in search of the elusive particles. Can we find stardust on the top of the BBC?

Featuring Jon Larsen, Dr Matthew Genge and Svein Aarbostad.

Presenter: Caroline Steel
