Morphology

astrophysics = physics (semi-transparent) = astro + physics

The word is clearly built from the combining form 'astro-' and 'physics', but the result is a specialized scientific term rather than an everyday, fully predictable combination.

Etymology

The word astrophysics comes from the Greek part astro- meaning 'star' and the familiar word physics, the science of 'nature' and 'matter'. So astrophysics is the study of the physical nature of stars and other objects in space.
