The Sky at Night team investigate the science of black holes and discover the incredible techniques being used to uncover their secrets.

A special Question Time edition of the programme, recorded at the University of Exeter as part of the British Science Association's Science Festival.

The panel is chaired by science journalist Dallas Campbell and made up of The Sky at Night presenters Chris Lintott, Maggie Aderin-Pocock and Pete Lawrence, who are joined on stage by Dr Claire Davies, who studies star and planet formation, and Dr Hannah Wakeford, who specialises in the atmospheres of exoplanets.

The panel answer questions covering all things astronomical from The Sky at Night's avid viewers and from audience members. We also hear about updates from the Voyager missions to life on other planets and discover where the panel would want to send future space probes if they had the chance.
