Through dogged determination, Jon Larsen has become driven to find space particles, which date back to when our sun was a baby, in the urban sediment that collects in the guttering of building rooftops. And, after he convinced a British planetary scientist to study his findings, years of work have finally paid off.
In 2011, Larsen reached out to Matthew Genge, of Imperial College London, with his plan to find dust particles in this seemingly unlikely place. Though distinguishing space particles from the zoo of man-made dust particles in a city environment was considered too difficult, the hurdle didn't deter Larsen.
