It's rather amazing, I thought they'd always known, or at least since Galileo.

I wonder how that affected the public of the time existentially. To know that there's entire galaxies outside of your own, when the one you know is already larger than you can fathom...

This is the story! Terrific accessible science writing by the brilliant Marsha Bartusiak. One of my favorite books ever.

Immanuel Kant in 1755 correctly speculated there were "island universes". Took a lot longer to prove though!
