So I’ve been watching a lot of video’s about how small we are compared to the universe. ( like [this](https://www.youtube.com/watch?v=9rrG5Nppaew&ab_channel=DANIELKAMARUZAMAN) ). And I don’t understand one thing. How do we know what our milky way looks like? And how do we know what the other millky ways look like?

Galaxies we can take pictures of in the night sky. You can’t always pick them out with the human eye but with powerful telescope settings it’s not an issue to get clear photos of their shapes.
Most galaxies fall into a handful of simple types and shapes. For our galaxy, the Milky Way, we can’t see the whole galaxy from the outside, but we can observe how all of the stars around us behave and piece together which of the common shapes our galaxy would have to be.
