The study or theory of the origin and formation of stars and celestial bodies.
From astro- (star) combined with -gony (origin or generation, from Greek gonos). This parallels 'cosmogony' (origin of the universe) but focuses specifically on stars.
Astrogony is what scientists study when they try to figure out how stars are born from collapsing gas clouds—it's the creation story that's actually provable and still happening around us.
