Handy Dandy Slider action between the two!

Technically the comparison is not totally fair, that Hubble image was taken in visible light, while Webb's in infrared. Dust blocks visible light stronger, so background stars are effectively hidden from Hubble, but not from Webb. Here [1] you can see same field in visible and close infrared taken by Hubble. Webb of course shines in all the fine details and faint stars number.

I think the comparison is (rightly) meant to highlight the different imaging capabilities of the two telescopes.

Now I am intrigued, the infrared image from Hubble seems to be able to see through even more clouds than JWST! What gives?

Fair? This is exactly why they are not the same type of telescope only Biggie Sized. Seeing these comparisons is the point. "Here's visible light, and now here's what's hiding behind the visible dust" should be the tag to everyone of these kinds of comparisons

*it's not so much that isn't fair, just that they show different things but the problems is that it is not explained

The fact that the tiniest features of the cloud appear preserved between the two images gives an appreciation for how big it is. The two photos are taken 27 years apart

I'm more surprised by how much change there is. All the bluish stars in the JWT version are also in the Hubble version, but none of the yellowish. Is that parallax movement or are they obscured by the medium mentioned in the article? ("no galaxies")

It will be fascinating to see what other objects hubble captured over the years look like in higher definition

The hubble image looks much more aesthetically pleasing, even though it clearly has less detail.

Actually Webb has marginally less resolution than Hubble. Even though Webb is significantly larger the wavelength used is significantly longer resulting in a resolution that is approximately half that of Hubble.

Of course the electronics are better so some of the image capturing is better but the resolution is not.

I would like to see Webb’s photo without so much lens flare on individual stars (not sure if that’s the right term). Just kind of toned down stars but the same level of detail.
