Very good introduction / overview here:
First pics from Webb to be released in about ten minutes (supposedly). Joe Biden will be presenting them.

Hundreds of galaxies, in a patch of sky that you could cover up with a grain of sand extended on your fingertip.
The cosmos is unimaginably massive. The orange objects are images of galaxies, 13 billion years ago.
Some nice Gravitational lensing in there. Awesome.

Just needs Rush 2112 written over it.

Amazing but at the same time the images although clearer than the Hubble are just as incomprehensible due to the scales involved. The data analysis from each planet/star may be of more use than the actual images in near/mid/far or whatever infrared type that is shown.
I had this thought while I was out on my bike and it's been twisting my melon ever since.
Given that any direction you point a telescope in is the direction of the big bang - because space itself has expanded since the moment the Universe started - it follows that if you look sufficiently into the distance, and therefore back in time - you'd actually be looking at the same early stars that you'd see if you pointed the same telescope in a completely different direction.
I think I need to confirm this with a cosmologist, but I do think it must be correct.
I watched this documentary on BBC2 last night about the whole development and deployment of the James Webb Space telescope. I was a Systems Engineer yet the work and detail involved just blows my mind:

I think that this probably isn't correct.

And again. Wow!!!
Neptune this time, stunning to see it like this ;D

My goodness! It looks like it's made of glass.

James Webb strikes again. This time it's Uranus.
