You definitely should not expect prettier. Or even more detailed.
Unless they are doing false color images, you should expect to see a lot of blackand white. Or black and red.
Hubble was setup for the visible light spectrum. JWST is not. We are NOT just gonna get better pictures of what we already seen with Hubble. Infact JWST cannot.
What we hope to see are things we have NEVER seen before. Things Hubble could not possibly see because they are shifted so far in to red they would be invisible to Hubble
I suspect what they will actually show on July 12 will be some kind of JWST +Hubble composite. So the parts in color will be what we already saw from Hubble. And then they will overlay something from JWST to show the parts Hubble could not see. Because just JWST by itself might be too boring for the average layperson.
But the important thing in keeping your expectations in check is knowing that the JWST pictures by themselves will probably be monochrome. And not sharper than Hubble. They cannot be sharper because the formula for angular resolution for a telescope is wavelength / diameter.
The wavelength of the IR light JWST is set up for is greater than 10x that what Hubble could see. And JWST is not 10x bigger in aperture/diameter than Hubble. The aperture only increased from 2.4m vs 6.5m
So best case, we will see some really cool pics we have never seen before. Just don't expect shaper or prettier.

Well of course there will be data, but what I mean is new data, as in stuff we don't already know. I'm kind of hoping that the JWST would provide new revelations that change or vastly improve our understanding of the universe and our galaxy.
Why would the JWST pictures by themselves be monochrome? I understand that it is for seeing infrared light, but NASA says it still can see some visible light as well (red and yellow part of visible spectrum).
When I say prettier I don't mean sharper, but more that it can see things that the Hubble cannot. ie a JWST image may add a bunch of stars that were hiding from a Hubble image because of the wavelength, resulting in a "prettier" picture.

Hubble's best images are arguably the Ultra deep field images. Linked below. This is the best pictures we have of what the deepest and oldest parts of space look like. But even with Hubble they took monochome images at 4 separate near IR wave lengths then did a false color composite for the final image.
The Ultra Deep Field image was taken by a sensor calibrated to between 1.0 to 1.6 µm wave lengths of light. So actually very near infra red. Definitely not in visible color spectrum like we would see with our eyes, but still relatively close to what our eye could normally see as "red".
The JWST is calibrated to 0.6–28.5 µm which is basically the very edge of visible light red into the far Infra Red. But not only that, the mirrors that they used plated with gold are poor at reflecting visible light. They are engineered specifically to reflect in the IR range.
Anyway long story short we probably either get some kind of composite false color images on Tuesday. Or just plain monochrome is possible too if they just want to highlight a specific spectrum.

man im stoked to see these images!
real talk tho, how hard will this get trolled for being "underwhelming"?
im expecting a pretty heavy blowback from people trolling and shit posting around the internet, calling it a bunch of meaningless images that dont even look that good, calling the jwst a giant waste of money and blah blah blah. smh.
i hope the images are so stunning that even the trolls will be like...

The mind melts at the thought that JWST has the potential for every image to be deeper than the Hubble deep field image. 
I think the thing I'm most interested in learning, other than seeing the first stars, is seeing what's in the zone of avoidance. Specifically, what comprises the Great Attractor. No doubt it's a supercluster of galaxies, but it's gotta be massive regardless.

I'm not sure what to expect but I'm enthusiastic. I want to see a 4k image of the sun surface, but pretty sure they don't care about that?

Yes. There will be new data. The purpose of the telescope is to do exactly what you're asking for. For example, it'll be able to study star formation and evolution of galaxies. it's going to answer a lot of questions and give us a better understanding of the universe.

ESA's Solar Orbiter got you covered there. https://www.esa.int/Science_Exploration/Space_Science/Solar_Orbiter
JWST will never come anywhere close to looking at the Sun. It would damage the instruments, which need to be cold. So the Earth and Sun sit in JWST's zone of avoidance.

I very much doubt they're going to be underwhelming if the context is clearly explained and understood. NASA knows damn well it has to fight for every penny and bit of attention it can in a world full on inconsequential shit, so my guess is they'll ensure the reveal is suitably newsworthy.
The fact Biden is doing the first reveal today rather indicates they are liking what they are getting...

I prefer false color images anyway. For composite shots, it makes it easier to see which parts of the image were captured in different wavelengths. For these IR shots, it has the potential to show us what the objects might look like if they were closer and not so red-shifted. I guess part of it is that I grew up with false color images. Monochrome images just don't look right to me.

Mr. Community
exoplanet atmospheric spectrography is, to me, the most exciting of the webb capabilities
and they've already announced the first batch of data will have some of that

So that I understand, the monochrome part is that way because we can't see infrared right?Hubble's best images are arguably the Ultra deep field images. Linked below.

And when they do false colour images, the colours aren't actually what it looks like because we don't know, but are just arbitrarily assigned to make understanding the image better?

im not saying they are going to be underhwelming, im syaing people are going to find a way to hate on it and ask why tf we spent 10B on a bunch of pictures
and i hope they are so stunning that those haters cant even get away with that

In SMACS JWST finds another Earendel but with a passing mass for elder spectrography.

Oh, I’m sure there would be some cunts on social media claiming it was underwhelming if it got a photo of two aliens fucking over a barrel.

yeah. kinda sad... but that's the most realistic prediction. especially due to the expansion of the universe, which will make everything drift apart more and more.
there will literally be a point in our galaxy (which by then will have fused with Andromeda) where any living being (if there will still be living beings by that time) will not be able to see other galaxies and it will be impossible for them to ever know about the big bang, about other galaxies and about the nature of the universe they live in, because everything will be red-shifted so far that it will be undetectable that anything else but our galaxy exists

Useful for context on the new picture. JWST vs Hubble.

Untrue, if there are still people on this planet the knowledge should've been passed down to future generations.
edit: nvm I read up on what you said and all life will be dead by then on this planet.

Here’s the first brand new image!
*reveals same image as yesterday*
Working in comms, this amateur hour presentation stuff is so cringeworthy to me.

Agreed. It's been embarrassing. From multiple technical glitches to cringe, fake presenting. I've had enough. I'll check out the rest of the data in my own time.

Possibly.
Breakthrough Starshot should launch in our lifetimes and bring back images and data from the Alpha Centauri system. Possibly life in that system, but who knows if it's intelligent.
I guess you're referring to true, human interstellar travel, Star Trek style. We're a long, long way from that, but it's not impossible. To be honest, this is probably doable technology in our lifetimes, but only with some huge changes to our society. Otherwise, it'll be hundreds of years.
Either way, we'll explore the galaxy one day. It's just a question of when.

Problem with those presentations are, they are completely focused on the people that work at it and really like a ton about it. For people randomly watching that just want to see some pictures its a endless cringe fest of bloated garbage that's just offputting.
They need to redo there livestream next time around. It's rough to watch and frankly i won't be watching the next one.

I’m not convinced humanity will even get past the heliopause with manned space flight, let alone out into the actual galaxy. Partly due to the massive potential energy requirements and cost, partly due to the fact we’ll probably blow ourselves up before then.
