Galaxies
The Milky Way and Andromeda: two different views
We live inside one galaxy and look towards another. Understand why their sky views differ.

Our view from inside
The Milky Way is our home galaxy. Its familiar band is our view through parts of its stellar disc, with dust shaping the visible structure. It is not a small external object with a single useful point to centre like a planet. A dark, clear sky is important for noticing the band with unaided eyes.
A neighbouring galaxy
The Andromeda Galaxy is also identified as M31 or NGC 224. It is a different object from the constellation Andromeda. A long-exposure photograph reveals much more colour and structure than an unaided-eye view. Expect observing conditions and equipment to affect the impression, rather than treating an archive image as a promised visual view.
Images and coordinates have different jobs
In Yorungez, a sourced photographic sky provides visual context while catalogue positions locate objects. Archive photos retain their credits and licences. Search for Andromeda or M31 and read the object type before focusing. The sky scene is a calculated educational view, not a live telescope feed.
