<p>New Delhi: Astronomers have discovered the fastest-growing black hole ever recorded -- the most luminous known object in the universe that is devouring the equivalent of one Sun every day.</p><p>The researchers at The Australian National University (ANU) noted that the black hole with a mass roughly 17 billion times that of the Sun, has set a record that may not ever be beaten.</p><p>"The incredible rate of growth also means a huge release of light and heat," said study lead author Christian Wolf, Associate Professor at ANU.</p>.ISRO holding discussions 'internally' on Chandrayaan-4 mission: Chairman. <p>"So, this is also the most luminous known object in the universe. It is 500 trillion times brighter than our sun," Wolf said in a statement.</p><p>A black hole is a region of spacetime where gravity is so strong that nothing, including light, can escape it.</p><p>Christopher Onken, co-author of the study published in the journal Nature Astronomy, noted that it was a surprise that the blackhole remained undetected until now, given what we know about many other, less impressive ones.</p><p>The blackhole was first detected using a 2.3 metre telescope at the ANU Siding Spring Observatory near Coonabarabran in New South Wales (NSW).</p><p>The research team then turned to one of the largest telescopes in the world – the European Southern Observatory's Very Large Telescope in Chile – to confirm the full nature of the black hole and measure its mass.</p><p>"The light from this black hole has travelled over 12 billion years to reach us," said Professor Rachel Webster from the University of Melbourne said.</p><p>“In the adolescent universe, matter was moving chaotically and feeding hungry black holes.
