Thanks for the direct links! > Webb's First Deep Field (NIRCam Image) Is this image distorted in any way at all? It feels like the galaxies are somehow oriented around a center spot. Not all of them, but enough to give the image a distorted feeling. Probably it's just my mind pattern matching against something that doesn't really exist.

Yes, it is distorted by a gravitational lensing effect of a massive galaxy cluster. Each image has a short discussion at this link, and a longer discussion linked via "Learn more about this image" for even more info: https://www.nasa.gov/webbfirstimages

I am confused because I thought it was an infrared telescope? Are these images as received, or are they frequency shifted post processed into the visible range?

As others have said: there is frequency shifting done. However, it is important to know that distant galaxies are red shifted making the visible spectrum be in IR. In the case of JWST the frequency shifted images may be close to the non-redshifted visible spectrum.

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

NASA's website gives a much easier view of the pictures: https://www.nasa.gov/webbfirstimages

Thank you. The linked website is horrendous.

The exoplanet analysis is what I'm most intrigued by. They're getting much more data than in the past on these. Of course they went for an easy gas giant target first (it has lots of water, which is great), but those Earth-like planets in the Goldilocks zone are gonna be some of the most exciting stuff that comes out of this. Looking forward to it.

1150 light years away! Imagine how much more details can be detected for stuff within 50 light years. Really, they should be already building 2nd James Webb. I am sure even 10 of them would get 100% utilization for their whole lifetime. I can only imagine what kind of needless political game is happening around prioritization of time slots for it. Or start working on next-gen, bigger, more resilient etc. It costs pea…

I fear there won't be any more JWSTs at all. People are already bitching about how much it cost and that all it does is make pretty pictures right here in this thread and there were many times that it came within a hair of having its budget slashed.

Super happy we have one JWST, and I hope fervently that it will outlast its original mission by a large fraction, every sign right now points in that direction.

You’re aware that this is just the observable universe? It may be completely irrelevant relative to the total universe. ;)

Thanks for posting these links! It was frustrating that the main NASA PR pages linked photos that were 1280x720. I guess that's to protect their bandwidth costs since much of the general public is probably viewing on mobile anyway and higher res would not only be slower but wasted bits. I just wish NASA had provided a link at the bottom of their low-res image pages to intermediate sized images (~4k) for desktop viewi…

I believe this page has what you want: https://www.nasa.gov/webbfirstimages Click on the image, twice, to get to a large-but-not-crazy resolution photo.

One of my favourite concepts from Douglas Adams was the Total Perspective Vortex, a form of punishment that would drive the victim insane by showing them the entire totality of existence and their place in it.

Wow. That's genius

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?

Yes, it's a combination of both the primary mirror and struts. The JWST website has a very helpful infographic explaining: https://webbtelescope.org/contents/media/images/01G529MX46J7...

Wow, thanks for this link. The level of communication around JWST's technology and launch has been amazing, and this is a great example of that.
