The Origin of Quasars (1990x3)

:

After the Second World War, the development of radio astronomy led to the discovery of Quasars, the nuclei of galaxies that generate such immense luminosities. The 60s and 70s led to the revelation of pulsars and black holes, potentially the most powerful sources of energy in the Universe. Professor Malcolm Longair explores what is known about these remarkable phenomena.
