Difference between Astronomy and Cosmology

[Salman Ranjha]

What Is the difference between Cosmology and Astronomy..?

 

[Bandersnatch]

Cosmology concerns itself with large scale structure of the universe and its evolution.
It does not deal with dust, planets, stars, galaxies and clusters of galaxies, nor any other individual objects and structures - these fall under the scope of astronomy and astrophysics.

There's some overlap, though, for example with observation methods.
