Is it also because the spiral is basically 2D, so from inside you can only see what’s basically 1D (aka the visible band of the Milky Way)? We would literally not have the perspective to see very much the rest of the galaxy in our sky.

Amazing, too, that the Andromeda galaxy is so bright that we can see it from our galaxy.

Can I buy this as a poster somewhere? I love maps, and somehow don’t have any space maps hanging up.

It was a fun fact until I clicked the link and realized that “arrows carried by the birds” are in fact arrows the birds have been shot with. Interesting history, thanks!
