The Euclid telescope, just launched today, will be able to observe galaxies out to 10 billion light-years. Here’s the largest map I could find (1 billion light years) that includes the Milky Way, Laniakea, the Shapley supercluster, the Perseus–Pisces supercluster, and the South Pole Wall.

    I seem to recall a few scifi stories with civilizations like that.

      Hitchhiker’s Guide had one that couldn’t see the sky, I remember. So they developed without ever thinking of anything beyond them.

      Nightfall by Isaac Asimov is kinda like that, it’s set on an Earth-analogue planet that orbits a system of six stars, so it’s never actually dark, except for one total eclipse every 3000 years.
