CAPE CANAVERAL, Fla. — Researchers have identified a quasar with a black hole at its center that may be the most luminous object in the universe. This quasar is growing at an incredible rate, capable of consuming an amount equivalent to the sun in a single day.
The record-breaking quasar shines 500 trillion times brighter than the sun. Scientists reported in the journal Nature Astronomy that the black hole fueling this quasar is more than 17 billion times more massive than the sun.
Despite appearing as mere dots in images, scientists believe quasars to be formidable entities.
The disk of luminous gas and other material orbiting a quasar’s black hole is akin to a cosmic hurricane.
“This quasar is the most violent place in the universe as we know it,” said lead author Christian Wolff of the Australian National University.
The object, known as J0529-4351, was initially discovered by the European Southern Observatory in 1980 and misclassified as a star. It was not confirmed to be a quasar until last year, after telescope observations in Australia and the Atacama Desert in Chile.
“What’s interesting about this quasar is that it’s hiding in plain sight and was previously misclassified as a star,” said Priyamvada Natarajan of Yale University.
Further analysis revealed that the quasar consumes the equivalent of 370 suns a year, or one sun a day, and the black hole at its center has a mass between 17 billion and 19 billion times that of the sun. More observations are needed to understand its growth rate.
Quasars are located 12 billion light years away and have existed since the beginning of the universe. One light year is 5.8 trillion miles.
