Huh, so the takeaway is that space is big but the stuff we can see is kinda close.

Nah, the takeaway is that space is big, and there's faint stuff nearby (stars), bright stuff far away (Andromeda Galaxy), faint stuff very far away (other galaxies), and very-very far away stuff that's somehow everywhere (cosmic background)

Hmm, doesn't pack quite the punch

Betelgeuse...

Don't you dare say that two more times.

Does it count if someone else in the same area says it once? Betelgeuse.

Betelgeuse (just to be sure)

The farthest individual star we can see with our naked eye if we look up into the night sky is only about 15,000 light years away, so that light takes 15,000 years to reach us. We can see the andromeda galaxy with the unaided eye 2.5 million light years away, but we wouldn't be able to see an individual star light up in it, which happens several times per year. We can see a lot more stars with a telescope, but the farthest star in our galaxy takes their light less than 100,000 years to reach us. With a really really good telescope, we can see individual stars in other galaxies, like in andromeda.

We would still see the initial formation. Light from when it was an accretion disk would hit us before light from the star.
