Beyond the Visible

The focus for this edition of The Sky at Night is on astronomical research that is beyond the scope of our eyes. We think of astronomy as something we do primarily using our sight. But we can now search the cosmos using radiation beyond the narrow band of visible light, beyond what we are able to see. We visit the UK’s foremost radio observatory, Jodrell Bank, and meet some remarkable, vision-impaired astronomers who are pioneering new techniques to carry out their research using their senses of hearing and touch.
