What fuels the brightest light in our universe?
The brightest lights in our universe are called quasars and they are created when massive amounts of material spirals into black holes. But where does this material come from? What fuels the brightest lights in our universe? An international team of scientists have detected light from the most luminous galaxy known. Hannah Laeverenz Schlogelhofer spoke with George Lansbury, from the Institute of Astronomy in Cambridge, to find out how the universe’s brightest lights are created and what this can tell us about the evolution of galaxies.
