They shine as brightly as a trillion stars, they’re powered by supermassive black holes… and until 2023 we had no idea how they came into existence. These are quasars, awesomely powerful cosmic objects at the centre of some of the most violent events in the universe. What exactly are quasars, and just how powerful can they be? Dr Vicky Fawcett, Research Associate in Astrophysics at Newcastle University, explains the power of the quasar to amazed space cadet Luke Turner.

•“A Quasar can be about a thousand times more powerful than the Milky Way Galaxy itself.” - Dr Vicky Fawcett

•“Quasar stands for quasi stellar radio source, because back in the 1960s when they were first discovered, they thought they were radio bright stars.” - Dr Vicky Fawcett

•"The central point of a quasar is so bright that they outshine all the stars in the galaxy.” - Dr Vicky Fawcett
