Thanks for finding those images! I threw together a page that lets you compare them via a slider. You should be able to zoom in on mobile!

The .gif comparison was a bit... upsetting since the color palettes are so limited and the resolution is so low, so it really didn't put JWST _or_ Hubble in a good light.

This is incredibly useful. Thank you!
would it make sense to balance the two images in terms of brightness? the hubble one just seems dimmer.

There is some extra "pinpoint" clarity in the Webb image, but it doesn't show (for instance) a bunch of new stuff, I was surprised at that.

There is definitely new stuff there – if you look closely.

The new stuff is of course faint and small. Otherwise Hubble would have seen it!

It looks like restoration of an old painting where the aged, yellowed varnish is stripped away to reveal the (much brighter and more detailed) original painting below.
Couldn’t you just do basic photo touch ups to get the Hubble to look about the same???
No. Webb looks deeper into the infrared and can see galaxies that Hubble can't see. There're some red galaxies in Webb (upper-right especially) that aren't in Hubble's at all.
amazing progress
