The Webb TELESCOPE recently revealed the extraordinary growth of ancient black holes that occurred very quickly, even faster than previously thought. Working with the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory, astronomers have identified a black hole growing at an incredible rate, absorbing more than seven million solar masses in 12 million years.
“This black hole is having a party,” said Julia Scharwächter, one of the study’s authors, describing how the black hole “gobbles up” the material around it very quickly.
For many years, the issue of the mass growth of early black holes has been a source of puzzlement among astronomers. JWST, as well as the Hubble Space Telescope, have identified galaxies containing black holes with masses reaching hundreds of millions to billions of times the mass of the sun in the early universe. However, the mechanism that allows black holes to grow so large in such a short time remains unsolved.
The discovered black hole, named LID-568, was first seen in the Chandra X-ray survey, which monitors X-ray emitting objects in the distant universe. When matter is attracted to a black hole, the energy released in the form of X-rays becomes brighter, the greater the accretion rate. This discovery shows that LID-568 has a very fast accretion rate.
The theoretical limit for the growth rate of black holes is called the “Eddington limit,” which describes the balance between the rate of matter falling into a black hole and the radiation it produces. This radiation functions as feedback, suppressing the accretion rate. However, the LID-568 exceeds this limit with a feedback level that is 40 times greater than expected.
Many people wonder whether these “primordial” black holes violate the laws of physics. The answer from the experts doesn’t have to be that way. “Super-Eddington” accretion like that of LID-568 is indeed possible, although only for a short time before feedback begins to inhibit the process.
This phenomenon has been observed before, and many consider it to be one way supermassive black holes grow so large so quickly.
LID-568 probably started out as a “light” black hole with a mass about 100 times that of the sun. The astronomy team predicts that this black hole began absorbing material about 12 million years after the Big Bang, when it was at the center of a large gas cloud that was eventually “swallowed” by the black hole.
“This discovery suggests that most of the mass growth of black holes can occur during periods of rapid accretion, regardless of the type of black hole seed,” said Hyewon Suh, one of the lead researchers.
LID-568 currently has a mass of about 7.2 million times the mass of the sun, much larger than the black hole at the center of our galaxy, Sagittarius A, which is only 4.1 million times the mass of the sun. However, the super-Eddington accretion process is episodic, and the hot gas expelled by the feedback can cool and fall back into the black hole, providing a chance for its growth to continue. (Z-12)

The Black Hole Party: LID-568 and Its Shocking Growth Spurt
Ah, the cosmos—it’s like a never-ending buffet where black holes are the insatiable guests, piling their plates high with solar mass like it’s an all-you-can-eat buffet for the universe’s most voracious eaters. And would you believe it? The latest party crasher in the cosmic kitchen is none other than LID-568, a black hole that’s eating faster than a teenager at a pizza party!
Welcome to the Universe’s Fastest-Growing Black Hole!
The James Webb Space Telescope (JWST) and its wingman, the Chandra X-ray Observatory, have recently uncovered that this ancient black hole—get this—has gobbled up more than seven million solar masses in just 12 million years! Yes, you heard me right! That’s the universe’s version of a 10-course meal, served at lightning speed.
“This black hole is having a party,” quipped Julia Scharwächter, one of the study’s authors, who may or may not have a flair for the dramatic. You see, LID-568 isn’t just munching on leftovers; it’s hoovering up material faster than it can be served, showcasing its impressive accretion rate. Imagine hosting a dinner party where one guest is alone at the buffet, and you’ll get the picture.
Unraveling the Mysteries of Cosmic Mass Growth
For ages, astronomers have been puzzled as they stared into their telescopes, scratching their heads while looking for answers about how these massive celestial vacuum cleaners got so big so quickly. JWST and its companion, the Hubble Space Telescope, have discovered galaxies filled with black holes weighing in at hundreds of millions—or even billions—of solar masses, dating back to the infancy of the universe. It leaves one to wonder: Are black holes just big, hungry beasts of gravity, or are they the universe’s ultimate overachievers?
Enter LID-568, which seems to have taken the cosmic speed limit and thrown it out the window. This black hole not only accumulates mass like a kid with a sugar addiction, but it also breaks the Eddington limit, a theoretical cap on how fast a black hole can gobble up matter before the radiation feedback kicks in. LID-568 is smashing that limit with a feedback level of 40 times what experts expected. It’s the astrophysical equivalent of auctioning off the last piece of cake to a room full of dieters. Spoiler alert: it’s not ending well for the cake!
Are We Breaking Physics? Not So Fast!
Now, some scoffers may raise an eyebrow and proclaim that these “primordial” black holes are breaking the laws of physics as we know them. But hold your horses! Experts assure us that while super-Eddington accretion—like what LID-568 is doing—can seem a bit cheeky, it’s perfectly permissible (albeit temporarily) before the universe reminds it to behave.
The Birth and Beyond: A Journey Through Time
Here’s the backstory: LID-568 likely began its life as a mere pocket change in the cosmic scale, a “light” black hole weighing in at around 100 solar masses. Its growth spurt kicked off roughly 12 million years after the Big Bang when it cozied up to a huge gas cloud that it eventually devoured whole, showcasing the classic high school trope of hitting the cafeteria at lunchtime and feasting on everything in sight.
As it stands today, LID-568 clocks in at a staggering 7.2 million times the mass of our sun! Take that, Sagittarius A—the esteemed black hole at our galaxy’s center that weighs only 4.1 million solar masses. But be warned, this cosmic carnivore’s lunchtime is an episodic affair, with hot gas being expelled and potentially falling back in like a diet gone wrong—because who can resist midnight snacking, right?
Final Thoughts: What’s Next for LID-568?
As we examine this extraordinary phenomenon, researchers are beginning to think that most black holes might bulk up during these rapid accretion periods, regardless of their “seed” type. So, what does that mean for the cosmos? It’s still anyone’s guess—but if LID-568 is any indication, we’re all in for one heck of a cosmic growth spurt!
So next time you look up at the stars and ponder the mysteries of the universe, just remember: somewhere out there, a black hole is partying like there’s no tomorrow, leaving us Earthlings wondering what we’re doing with our lives.

Increased growth, it only lasts for short periods before feedback mechanisms begin to rein in the process. So, while LID-568 is currently throwing quite the cosmic bash, it won’t be able to keep up this pace indefinitely without some party crasher to manage the chaos!
The history of black holes like LID-568 reveals a fascinating tale of cosmic evolution. Likely originating from a “light” black hole around 100 solar masses, LID-568 started feasting just 12 million years after the Big Bang, pulling in mass from a vast gas cloud surrounding it. This early growth spurt hints at a quicker and more dynamic path toward supermassive black holes than we ever imagined.
The Bigger Picture: What This Means for Our Universe
The implications of LID-568’s growth reach far beyond its own insatiable appetite. This discovery challenges our understanding of when and how black holes reach their staggering sizes. Lead researcher Hyewon Suh emphasizes that this suggests most mass growth for black holes can happen during rapid accretion phases, regardless of their initial mass. This revelation might reshape our models of black hole formation and growth, helping astronomers reconcile the existence of massive black holes in the early universe with the physics that govern them.
Currently boasting a mass of about 7.2 million solar masses, LID-568 easily outstrips the black hole at the center of the Milky Way, Sagittarius A, which sits at a comparatively meager 4.1 million solar masses. However, much like a fad diet, this explosive growth may not last forever. The atypical feedback from the intense accretion may allow gas to cool and eventually return to LID-568, stirring the potential for ongoing growth.
Final Thoughts: The Ongoing Cosmic Feast
As we look deeper into the universe with instruments like the JWST, the party will likely continue, revealing more surprises in the cosmic banquet of black holes. For LID-568, the feast may be far from over, holding secrets that could redefine our understanding of the cosmos. The black hole party is just getting started, and we’re all invited to the cosmic show!
