Dr Becky Smethurst and Izzie Clarke investigate the cosmic coincidences that formed the Earth and explore whether there are earthquakes and volcanoes on other planets. Plus, astronomer Robert Massey joins them to chat all things #cometNEOWISE and what else to look for in the night sky this month. 

With special thanks to Dr Amy Gilligan from the University of Aberdeen, Professor David Rothery from the Open University, and everyone who shared their images of Neowise.
