Astronomers have detected the brightest and fastest-growing black hole to have existed in the last 9 billion years. The enormous cosmic entity is 3 billion times more massive than the sun and swallows up an Earth-size chunk of matter every second.
The new supermassive black hole, known as J1144, is around 500 times as Sagittarius A*, the supermassive black hole at the heart of the Milky Way, which was recently photographed for the first time. A ring of superhot plasma around the enormous void also emits around 7,000 times more light than our entire galaxy.
Australian astronomers discovered the cosmic juggernaut using data from Australian National University's SkyMapper Southern Sky Survey, which aims to map out the entirety of the sky in the Southern Hemisphere. Locating the supermassive black hole was like finding a "very large, unexpected needle in the haystack," the researchers said in a statement(opens in new tab).
"Astronomers have been hunting for objects like this for more than 50 years," lead researcher Christopher Onken, an astronomer at the Australian National University (ANU) in Canberra, said in the statement. "They have found thousands of fainter ones, but this astonishingly bright one had slipped through unnoticed."
The black hole's voracious appetite dwarfs that of other similarly huge supermassive black holes. Normally, the growth rates of these enormous cosmic entities slow down as they become more massive, according to the statement. This is likely due to increased Hawking radiation — thermal radiation that is theorized to be released from black holes due to the effects of quantum mechanics.

Simply amazing.
I mistook this to be an article about Whoopi Goldberg.
There must be a lot of earth size chunks of matter sitting around nearby
Uh, a chunk of matter the size of earth, in the overall scheme of things, ain’t much. Besides, putin............
I thought it was about voter fraud in Georgia.
They are describing the government.
Black Holes Lives Matter.

These scientists must previously been Obama origination researchers, well trained in searching for a black hole.
That’s about 1 sun every 4 days. But, is this how much actually makes it across the event horizon, or is torn up by the accretion disk? Because it matters somehow.
It’s the fault of “climate change”......
A process of assimilation.
...and when it runs out of earths to consume its gonna get mad!

NOT IMPRESSIVE.
Stacy Abrams eats more than that every day.
Yeah good thing we still have 10.5 years before that happens ...
Don’t be talkin’ smack about the gov of Georgia.
The universe’s vacuum cleaner.
Leaving aside, for a moment, that Hawking radiation is just a "theory" for which not a single piece of evidence has been obtained, Hawking radiation would be increasing only as the black hole gets smaller and smaller...
Not "larger & larger"...
Okay - please explain something to me -
If a black hole gets 'larger' by ingesting more mass,
then it's gravitational pull would increase, right?
So if the gravitation is greater, then wouldn't that mean
that the black hole is squished more - and therefore be
physically smaller ??
Can the adjectives 'Big' and 'Small' be accurately used to describe black holes?
I guess you must be more descriptive of the context.
Eh?
