50 years of X-ray astronomy

Could jets of X-rays from black holes hold the key to the Earth's energy demands? Maybe not in the short term, but as scientists begin a sixth decade of studying stellar X-ray sources - the prospect of harnessing them may well be edging closer.

Take a look at how far knowledge and research into these violent cosmic X-ray emissions has come in 50 years - with celebrated UK space pioneer, Professor Ken Pounds from the University of Leicester.
