There's a very cool book of photos of micrometeorites:

In Search of Stardust: Amazing Micrometeorites and Their Terrestrial Imposters

By Jon Larsen, ISBN: 9780760352649

I recommend the Werner Herzog’s documentary “Fireball” (https://en.m.wikipedia.org/wiki/Fireball:_Visitors_from_Dark... ) which has a segment with Jon Larsen and his process for capturing images of micro meteorites

> The roaring of a vacuum cleaner breaks the silence and researcher Dr Penny Wozniakiewicz, dressed in hazmat suit with a bulky vacuum backpack, carefully traces a gutter with the tube of the suction machine.

I reckon every week my house gets a load of meteorites on it. Please email to make a weekly arrangement for cleaning the, er, meteorites up. My rates are very reasonable!

Why the hazmat suit? It's not like they're going to contaminate the samples with space dust accidentally brought from home (or rather if they did they wouldn't care anyway - they want those particles not specifically what's on the cathedral roof)?

It mentions "they are protecting themselves from bird flu, possibly contained in the droppings and bird bones we see on the roof"

Ah, thanks
