Cosmic dust might be closer than you think - in fact, it might even be on top of a nearby tall building. \n\nAnd that\u2019s exactly where Dr. Penelope Wozniakiewicz, Senior Lecturer in Space Science at the University of Kent, is focusing her searches as she and her colleagues are exploring cathedral roofs to find traces of these particles.\n\nBut why? What can we learn from cosmic dust and what is it in the first place?\n\nPenelope joins Jonathan to discuss.
