Morphology

astronomer = astronomy (transparent) = astro + nom + er

The word is a standard agent noun built on 'astronomy' plus '-er', so its meaning is directly recoverable from the base.

Etymology

The word astronomer comes from old Greek parts astron 'star' and nomos 'law', and shares the same root as astronomy. So an astronomer is a person who looks for the 'rules' or patterns of the stars and other objects in space, which is why they study stars, planets, and the sky.
