That answers my question.  Bit makes e wonder:

How many such things are out there in our galaxy?  How common are they?  How close are the other ones?

What does a night sky look like there?  Are we in one of those clouds too?

Are those all stars in our own galaxy? I know the pillars are in our galaxy, but are all the stars in the image also?

It's not even a blink of they eye in the scale that we're seeing here. That thing will look more or less the same a million years from now.

Those are *stars* that formation is spitting out. Our brains literally can't visualize or imagine how large it is.

Probably easier for some to visualize it as a satellite TV dish antenna on top a camper.  They don't really need to know about the layers of insulating blankets or laptop film, whatever.  Except the dish antenna are polished metal mirrors

More new discoveries that surprise astronomers, don't fit current theories very well.

In what James Webb Space Telescope researchers call a "whole new chapter in astronomy," the observatory has helped to locate two early galaxies, one of which may contain the most distant starlight ever seen.  In a tweet, the international team said the unexpectedly bright galaxies could fundamentally alter what is known about the very first stars.

"With Webb, we were amazed to find the most distant starlight that anyone had ever seen, just days after Webb released its first data," Rohan Naidu, of the Harvard-Smithsonian Center for Astrophysics and the Massachusetts Institute of Technology, told NASA of the more distant GLASS galaxy – referred to as GLASS-z12 – which is believed to date back to 350 million years after the big bang.

"While the distances of these early sources still need to be confirmed with spectroscopy, their extreme brightnesses are a real puzzle, challenging our understanding of galaxy formation," the University of Geneva's Pascal Oesch said.

JWST discovered PHOTOCHEMISTRY in an exoplanet's atmosphere (this is a BIG deal) ft. Dr. Jake Taylor


Adorably energetic astrophysicist chick reporting that JWST has found evidence of photochemistry in exoplanet WASP-39b’s atmosphere:

Using three of its instruments, the JWST was able to observe light from the planet’s star as it filtered through WASP-39b’s atmosphere, a process known as transmission spectroscopy. This allowed a team of more than 300 astronomers to detect water, carbon monoxide, sodium, potassium and more in the planet’s atmosphere, in addition to the carbon dioxide. The gives the planet a similar composition to Saturn’s, although it has no detectable rings.

The team was also surprised to detect sulfur dioxide, which had appeared as a mysterious bump in early observation data. Its presence suggests that a photochemical reaction is taking place in the atmosphere as light from the star hits it, similarly to how the Sun produces ozone in Earth’s atmosphere. In WASP-39b’s case, light from its star, which is slightly smaller than the Sun, splits water in its atmosphere into hydrogen and hydroxide, which reacts with hydrogen sulfide to produce sulfur dioxide.

“These spectra are just exquisite in their detail, and reveal an additional way that the star affects the planet’s atmospheric composition, through photochemistry,” says Victoria Meadows, an astronomer at the University of Washington in Seattle.

“Photochemistry, because it is such an important process here on Earth, is probably an important process on other potentially habitable planets,” says Jacob Bean, an astronomer at the University of Chicago in Illinois and the observation team’s co-leader. Until now, “we’ve only been able to test our understanding of photochemistry in our Solar System. But planets around other stars give us access to completely different physical conditions.”

There were a lot of cost overruns with JWST, and in the end, it cost $10-billion over 17 years.

Sounds expensive, but really, that's pretty cheap compared to the money we're throwing at things like Ukraine right now.

We should have built 5 of the damn things and launched them all up at once.

Yeah, but they’re also getting twice as much mission time than they expected (twenty years vs ten years) out of the thing because of how well the orbital insertion maneuver went.

We’re definitely getting our money’s worth out of this thing

Webb is representative of the NASA way of doing things. That way of doing things can be impressive but I believe that we are going to see some pretty dramatic changes soon with launch costs finally trending downward.

JWST's successor: The Carl Sagan Observatory - a 12 METRE optical telescope searching for exo-Earth


It would be interesting if the Carl Sagan Instrument is launched, but I don't expect it to be. With the new generation of launch vehicles on the drawing board I anticipate there will be changes to the design of future space telescopes. Instruments built to be a bit more rugged as opposed to having to shave every single possible gram of weight.

I'm not so sure we'll learn more, though we've already learned that what was thought as 'known science' isn't correct since looking back so far (through time), they see more and more galaxies rather than the void before "big bang".  They haven't really dumped any new images of their super deep looking images have captured, other than the first one that says "this is supposed to be empty space right after Big Bang, but it is full of galaxies" so they're scratching their heads.

Exactly!

once I saw the Hubble deep field images after they were published, I had a strong feeling that if they ever built a telescope that could see much further, that this would be the case. I'm curious how they will change their interpretations based on all this new data.

While I think they were trying to be "book smart" using a Lagrange Point for the telescope, I think they are finding that it is a garbage collection point more suited for a hardened space station which sucks.  I hope that their "aim it at nothing solution" works, but I think that will only help somewhat and it will have a much shorter life than planned

Our country has never been shy about throwing stupid money at war and death.

This project represents the end of OLD commie style projects and we are shifting toward getting more bang for our buck, science wise.

These will become cheaper and more plentiful now that our space market has shifted closer to capitalism.

while all of this is amazing, the absolute mind bending largeness of it all. I have had discussions that we are all in our own place.
relatively speaking
we cannot be at the absolute same space  from each other.
if you and i are having a conversation, each at 3 feet apart, and another hears that conversation at 3 feet 6 inches, for all involved it happened at ethe same time, but person 3 is behind.

Had an opportunity to attend a NASA presentation on JWST at a local college. It was very glossy, but still interesting to hear it from an engineer who works at nearby Glenn.



The school's observatory was open after, which was a nice treat. I took my niece because she's expressed interest in the cosmos, and now she wants to be an astronomer. Unfortunately, we had scattered clouds tonight so there were only brief glimpses for the stars through the telescope.



Didn't learn anything groundbreaking about the JWST but it was special to see it amaze an 11 year old.
