In these podcasts Royal Observatory Greenwich astronomer Radmila asks our visiting astrophysicists and space scientists about their career background, why they became an astrophysicist, why we should care about science and which unsolved mystery keeps them up at night.

In this episode Radmila talks to Dr Paniez Paykari who is a researcher in cosmology at University College London. Her primary field of research is on the cosmic microwave background – the ancient radiation from the Big Bang that can be seen in all directions.
