the Southern Ring Nebula (MIRI Image) is bizarrely very low res? https://webbtelescope.org/contents/media/images/2022/033/01G...

Wow you're right, huge difference in the sizes of the "full res" images:

> MIRI: Full Res, 1306 X 1133, TIF (1.78 MB) [1]

> NIR Cam: Full Res, 4833 X 4501, TIF (24.06 MB) [2]

Maybe it's a mistake, they suggest it should offer an "incredible amount of detail":

  This Mid-Infrared Instrument (MIRI) image also offers an _incredible amount of detail_, including a cache of distant galaxies in the background.

A lot of the pictures have some bright stars with 6 long lens flare like points coming out of them in a consistent pattern. Is that because of the hexagonal shape of JWT's lenses/mirrors?

More or less. That's how they've explained it in the past.

Is there an easy way to just scroll through the images?

I kinda love this comment. It highlights the absurd dichotomy between what "experts" see and what "lay people" see when they look at the same thing. Parent just wants to see some cool images from Earth's latest and greatest space telescope, preferably in a convenient way. Astrophysicists from NASA, ESA, et al. are hanging off the data and details from every last photon collected - each one having traveled billions of…

Yeah? And? So?

If it's the pretty pictures that gets people interested, then show them the pretty pictures. We all paid for it, so let us see them.

Would highly recommend spending time gazing at each one in full resolution. The deep field in particular is underwhelming until you look at it as closely as possible. Then it becomes extraordinarily spectacular.

Give it some time, and NASA will definitely get a gallery where imagery can be viewed in a more friendly browsing experience. These are the astro-imagery equivalent of "hot off the presses". They just haven't had time, nor enough content, to get a full gallery up yet. All of the other platforms have these types of galleries, so just a bit more patience is needed from all of us while the JWST gets to work! (I'm sitting on my hands trying to be patient myself)

Well, it's incredible in the sense that I can't believe it

Why should these two be mutually exclusive?

Even within research projects we wish to find well organised datsets.

Asking about scrollable images seems to be a fair question to me, especially in the context of a press release.

Yeah, it's the hexagonal shape. The objects with the 6 diffraction spikes are overexposed compared to the rest of the objects in the picture, so they're generally brighter and/or closer objects.
