That image looks like the one from the hubble telescope on the horizon programme I've just watch on BBC4.

Goes back a lot further than Hubble

I have a fairly good grasp of the basics.
Space is up.

Not if you're in Oz..

Gloves on

So does it slow down, can it slow down? Messes my head up.

Doesn't slow down but the space it travels into is being stretched. The further it travels the further it is stretched into the red part of the light spectrum.

That's why this James Webb telescope sees in near infrared so as to detect the light that we can no longer see in the visible spectrum. So we hopefully can see details from the first kinds of galaxies 13.4 billion years ago.

So far Webb has shown the composition of a galaxy from 13.1 billion light years away. The furthest distance that spectroscopy has ever been used.

It shows one of the first galaxies is made mainly of hydrogen and oxygen, as scientists predicted.

Also has show that an exoplanet has evidence of water vapour/clouds.

Fascinating quick analysis of the first JWST image:
