- gattr 6y agoI guess - we have maps of galaxy distribution out to a few billion light years, like the one from the 2dF survey [1]. "Celestial North/South Poles" are just the points in the sky in the direction of the Earth's rotation axis.

- chmod775 6y agoThere's a few interactive 3D maps of the universe floating around. A really cool one was posted this year on HN, but I can't find it anymore. In any case, here's another one: https://in-the-sky.org/ngc3d.php https://in-the-sky.org/ngc3d.php North/South pole are on that map. Since we can observe the universe for the same distance in every direction, I guess it makes sense that we'd give the resulting sphere a north and a south pole.
