Newly discovered galaxies, dubbed "Little Red Dots," have long puzzled astronomers due to their striking appearance and properties. These tiny, glowing objects are thought to be harboring supermassive black holes that defy explanation, with some estimates suggesting they could be as massive as 10% of the galaxy's total mass.
Researchers had initially assumed these enigmatic galaxies were compact, distant galaxies, but this theory didn't quite add up. They then turned their attention to a second possibility: that the Little Red Dots were supermassive black holes themselves. However, this theory also faced significant challenges.
Enter Vadim Rusakov and his team, who stumbled upon an innovative solution while studying data from the James Webb Space Telescope (JWST). The researchers discovered that the unusual appearance of these galaxies could be explained by a previously unknown stage in the evolution of supermassive black holes.
According to Rusakov's team, young supermassive black holes may go through a "cocoon phase" where they grow rapidly surrounded by high-density gas and dust. This dense cocoon acts as a shield that blocks the high-energy X-rays and radio waves that typically signal an active black hole's presence. Instead, these objects emit light at very specific wavelengths in infrared, making them visible to JWST.
By analyzing data from 12 Little Red Dot galaxies, Rusakov's team found that their intrinsic velocity was much lower than previously estimated. This led to the conclusion that young supermassive black holes are likely tens of millions of times more massive than initially thought – a figure much closer to the standard galaxy-to-black-hole mass ratio observed in our local universe.
The discovery of this cocoon phase represents a significant breakthrough, as it provides new insights into the early universe and how galaxies formed. While questions still remain about the duration and frequency of this stage in black hole evolution, researchers are optimistic that continued analysis of JWST data will shed more light on these enigmatic objects.

Vadim Rusakov and his team were all like "hey lets think outside the box" and came up with this crazy cocoon phase theory where young supermassive black holes just chill in a high-density gas cloud thingy and grow rapidly surrounded by it 
I think its pretty mind blowing that scientists figured out that those little red dots could be young supermassive black holes surrounded by a shield of gas and dust 
Like, who would've thought?! And now we know they're probably tens of millions of times more massive than initially thought 
. the idea that young black holes are tens of millions times more massive than thought is wild 
! I mean, think about it - we're talking supermassive black holes that are way more massive than we thought, and they're surrounded by this 'cocoon' of gas and dust that makes them invisible to us until JWST came along. It's like our technology is giving us a new pair of eyes to see the universe in ways we never could before 
.
.
... it's just wild to think about how our understanding of the universe has changed because of this one discovery. I'm not even kidding when I say that if we keep analyzing JWST data, we're gonna uncover some more mind-blowing secrets 
. I'm so excited to see what more researchers come up with when they keep digging into this data from JWST! 
. This cocoon phase thing makes so much sense, especially when you consider that young supermassive black holes might be hiding in plain sight, not radiating all that energy 
.
. These scientists are helping us unravel some of the biggest mysteries out there, and I'm excited to see where this research takes us next 
. The cocoon phase theory is mind-blowing - can you imagine having these massive voids of gas and dust around a black hole, blocking all the usual signals? It's wild to think that JWST is now able to spot them because of this unique emission pattern 
. JWST is really proving itself as a game-changer in astronomy 
I swear, scientists are so smart that it hurts... 
Anyway, congrats to Rusakov's team, I guess. New insights into the early universe and all that jazz... 
It makes total sense now that we think about it, those infrared signals were the only clue they needed to crack the code 
.
. The implications are huge - it totally changes our understanding of galaxy formation and black hole evolution 
. Can't wait to see what other secrets JWST uncovers next! 
Vadim Rusakov and his team are like total geniuses! I mean, who knew these objects could be hiding in plain sight all this time? The fact that they're tens of millions of times more massive than we thought is mind-blowing. It's like the universe just threw us a curveball, you know? 
But seriously, this discovery is huge and it's gonna change the game for astro researchers. I'm hyped to see where this takes us!
