 An international group of astronomers have discovered and measured the most distant supermassive black hole to date.
 This newly-discovered black holes sit in the centre of an ultrabirght quasar that was emitted just 690 million years after the Big Bang. The remarkable thing is that this light has taken almost 13 billion years to reach us - almost the same age as the Universe.
 The discovery, which was made possible through data collected by the DECam Legaxy Survey (DECaLS) at the CTIO Blanco telescope, has shown that the black hole has a mass of approximately 800 million solar masses - humongous for today's standards. This has lead to some astronomers theorizing that the very early Universe might have had ripe conditions allowing the creation of very large black holes, such as those with masses reaching 100,000 times the mass of the Sun.
 “Gathering all this mass in fewer than 690 million years is an enormous challenge for theories of supermassive black hole growth,” said team leader Dr. Eduardo Bañados, from Carnegie Observatories.
