galaxy - What part of the milky way do we see from earth?

Fraser Cain:

We’re seeing the galaxy edge on, from the inside, and so we see the
galactic disk as a band that forms a complete circle around the sky.

Which parts you can see depend on your location on Earth and the time
of year, but you can always see some part of the disk.

The galactic core of the Milky Way is located in the constellation
Sagittarius, which is located to the South of me in Canada, and only
really visible during the Summer. In really faint skies, the Milky Way
is clearly thicker and brighter in that region.
