1: Seeing The Invisible Universe

From black holes to dark matter, this first episode of the Royal Astronomical Society's new podcast explores the odd things in space we can't see. Plus, hosts astrophysicist Dr Becky Smethurst and science journalist Izzie Clarke are trusted with a book from 1566 and Robert Massey, the Deputy Executive Director of the RAS, shares his top tips for stargazing at home.

With special thanks to Dr Rebekah Higgitt from the University of Kent, Professor Hiranya Peiris and Professor Andrew Pontzen from University College London.

And yes, we've had to change the name of our podcast. All shall be revealed in episode two...
