Record-breaking quasar 500 trillion times brighter than the sun discovered | Science & Tech News<\/p>\n
<\/p>\n
A quasar 500 trillion times brighter than the sun has been discovered by astronomers who say it may be the brightest and “most violent” place in the universe.<\/p>\n
The huge black hole powering it is said to be between 17 and 19 billion times the mass of the sun and growing at the fastest rate ever seen.<\/p>\n
Quasars are the bright cores of ‘active galaxies’ – those that have supermassive black holes consuming huge amounts of matter.<\/p>\n
The record-breaking quasar, discovered by an Australian-led team, is swallowing the equivalent of a sun a day as it pulls in vast amounts of gas.<\/p>\n
The rotating disc of gas around its black hole has been likened to a cosmic hurricane – which experts say emits so much energy it’s more than 500 trillion times more luminous than the sun.<\/p>\n
“This quasar is the most violent place that we know in the universe,” said lead author Christian Wolf, from the Australian National University.<\/p>\n
It was thought to be a star when first spotted in 1980, but got reclassified as a quasar last year following observations in Australia and Chile’s Atacama Desert.<\/p>\n
Astronomers now think it’s consuming the equivalent of 370 suns a year, about one a day, making it the fastest-growing black hole to date, according to the European Southern Observatory (ESA).<\/p>\n
The quasar is known as J0529-4351 and is 12 billion light years away (a light year is 5.8 trillion miles).<\/p>\n
