Astronomers staring out to the farthest reaches of the universe, and hence the deepest depths of time, have been puzzled to find supermassive black holes . How could such behemoths have had time to swallow up so much matter when the universe was so young? With new observations of one of these youthful giants—a black hole 1 billion times the mass of the Sun and less than 1 billion years old—astronomers now have a possible answer.
They found the black hole was connected to six nearby galaxies by filaments: feeding tubes for the monster in their midst. Assembling this family portrait (imagined above) took many observations—some lasting all night long—with some of the world's largest telescopes, including the European Southern Observatory's Very Large Telescope in Chile.
This may worth something:
A Black Hole at the Center of Earth - Is This Study Fake?
IFLS found some of the authors have been involved in previous wild and questionable papers, suggesting an ecosystem of either fakers or conspiracy theorists.
Bystanders often talk about peer review like it’s a way to ensure a paper is factually correct, but that’s not always the outcome, and it’s not even the goal. Sometimes, legitimate scientific or mathematical work is so complex that even “peers” struggle to analyze it, especially in the short time frame before publication.
Strange Research Paper Claims There's a Black Hole at the Center of the Earth
An outrageously strange paper claims, among other things, that there's a black hole at the center of the Earth.
And somehow, it got published in an actual scientific journal, the Open Access Macedonian Journal of Medical Sciences — baffling mainstream scientists.

"Size of this DNA black brane is 109 times longer than the size of the earth's core and compacted interior it," it continues. "By compacting this long object, a curved space-time emerges, and some properties of black holes emerge."
M87*: History-making supermassive black hole seen to do a shimmy - BBC News
When scientists presented the first ever picture of a black hole last year, it was hailed as an extraordinary breakthrough.
And it gives us some fresh perspectives on the object known as M87*, which has the monster mass of 6.5 billion Suns.

This is probably the result of M87* shredding and consuming nearby matter caught in the ferocious pull of its gravity.
The matter, heated to billions of degrees, twists and turns through what are intense magnetic fields. And as it does so, the region of brightness seen in the black hole's encircling ring of gas appears to wobble.
Many things are taking place:
Star cluster feeding the black hole in our Milky Way has gobbled up a dwarf galaxy: Study-
Our galaxy Milky Way has a huge black hole in its core. The black hole is fed by a nuclear star cluster, which is the largest star cluster in the galaxy. Hence, they shine the brightest and weight around 25 million times as much as the sun. However, a recent study shows that it may have eaten up a surrounding smaller star cluster or maybe a dwarf galaxy to attain its shine.
Tuan Do, an astronomer at UCLA, led the recent study to find answers about the Milky Way's core and found that "stars with less metals than our sun [seemed] to be moving differently than the stars with more metals".
At the Edge of Time, a Litter of Galactic Puppies - The New York Times
Astronomers announced on Thursday that they had discovered a giant black hole surrounded by a litter of young protogalaxies that date to the early universe — the beginning of time.
The black hole, which powers a quasar known as SDSS J1030+0524, weighed in at a billion solar masses when the universe was only 900 million years old. It and its brood, the astronomers said, represented the infant core of what became a vast cluster of galaxies millions of light years across and encompassing a trillion suns worth of matter.
The first black hole ever photographed gets a glam up — it's now glittering

The M 87 black hole, the first body of its type ever photographed by astronomers at the Earth Horizon Telescope, shows an unusual glitter…
T he first image of a black hole released in 2019 showed the body at the center of the galaxy M87 to look almost exactly as Albert Einstein predicted a century before.
A new analysis of data from that study sheds additional light on the lightless object — The ring is glittering.
MAXI J1348−630 is a black hole X-ray binary, observations suggest
During these outbursts, astronomers observe mainly the hard and soft spectral states. In the hard state, the spectrum is dominated by a power law-shaped continuum, while in the soft state, the spectrum is dominated by a disc-blackbody emission. However, some black hole XRBs also exhibit an intermediate state in which the hard power-law continuum and a disc thermal emission component make approximately the same contribution to the total spectrum.
MAXI J1348−630 is an X-ray transient discovered on January 26, 2019 with the Gas Slit Camera (GSC) of the Monitor of All-sky X-ray Image (MAXI) aboard the International Space Station (ISS). Follow-up observations of this source suggest that it is a black hole candidate in a binary system.

On Earth, the toxic gas is produced by microbial life. Could the same be true on Venus? Now, the debate begins. https://t.co/zDrmXGCTCY AstronomyMag (from Our tiny corner of the cosmos) Thu Sep 24 11:00:29 +0000 2020
