Ask a Mathematician / Ask a Physicist helped. I was thinking about a single star, but of course there’s an infinite number, all with different lifespans and distances, so we only look at the ones within our observable window, not the ones we have missed.
Space and stuff

Now that’s a whacky orbit. Had no idea you can orbit like that! Amazing!

Thought they’d use centigrade.
Switch it from ‘English’ to metric

We have quite a bit of fuel margin right now relative to 10 years. Roughly speaking, it’s around 20 years of propellant,"

The JWST should have reached it L2 by now
Edit: confirmed

Images available approx. 6 months after launch.
Yeah, has a lot cooling to do between now and then.

For me it was the Cygnus loop supernova remnant taken in 1991

Jogort Wow, for me it came up with my fav photo! What are the chances of that?
Hubble Deep Field, this image captures several hundred galaxies that had never been seen before. Some galaxies are near and some are very far. Their various shapes and colors provide clues about the evolution of the universe.
I remember first seeing this photo. It’s only when you zoomed in that you saw that the numerous stars were actually galaxies. It was one of those OMG moments, when my tiny brain tries to realise how massive the universe is. It’s like the other OMG moment, when I looked at stars and realised they’re suns.
