Way to brighten my day with awe and wonder, way to ruin my day with existential dread about our place in the universe.
Existential dread pro-tip: The Wikipedia page on "Ultimate fate of the universe" is a fantastic way to compell the question of why anything ultimately matters. Coming up with personal answers to this is the ultimate character resolve exercise!
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?

consciousness is a hell of a drug
Dumb question. Why can’t we focus on a single exoplanet, look for mountains, grass, buildings? Why am I so stupid but isn’t this the obvious thing to do?

Ok to be honest I know it's not cool to admit it, but so far it all looks the same. If someone told me that the Webb picture was taken by Hubble I would not have thought about it for an extra second. I'm hoping that in the future we see pictures of locations and environments that are mind-blowing to the average person who loves space.
The difference is in a) the details and b) the length of time the telescope has to gather light to get the photo. JWST got the photo in hours when Hubble took weeks, and there's easily 10x as many objects in the JWST shot. JWST can thus observe much fainter and much more distant objects - galaxies billions of years old, exoplanets, etc., and it can do more of it .

Yeah, that's not very good implementation. PetaPixel usually have good content, but using a GIF to compare these two images? Come on! You can see the compression artifacts very easily.

Another neat idea is to use the Sun as a gravitational lens. But you you would need it put it way past Pluto to get proper focus. So maybe another hundred years to get tech and resources to that point.
