Haley Gomez on cosmic dust

Jim Al-Khalili talks to astrophysicist Haley Gomez about defying expectations and becoming a world expert on cosmic dust.

For centuries, cosmic dust was a major source of irritation to optical astronomers because, like smog, it stopped them from seeing the stars. Now studies of these tiny particles are challenging some deeply held assumptions about the physics of the universe.

Haley’s research has changed the textbook explanation of how cosmic dust is formed and helped to open our eyes to just how many galaxies there are in the universe.

In 2018 she was awarded an MBE for services to physics and inspiring the next generation of physicists and astronomers from less privileged communities. A cause which is very close to her heart.
