General Astronomy

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.

No it's NASA made/owned but also contributions from other space agencies including the european one, ESA.

Current thinking of various astrophysicists is that life, as in Civilisations, will be extremely rare. Less than one per galaxy per many millions/billions of years. There probably hasn't been as advanced civilisation as us within the last billion years in our local galaxy group.

They think this as we detect no radiowave signals.
Even our first radio waves are not yet 100 light years out from earth.
