astrophysics

Celestial physics field

Astrophysics is the branch of astronomy that applies physics to understand celestial objects and phenomena—stars, galaxies, black holes, the origin and evolution of the universe.

Where astronomy maps and catalogs the heavens, astrophysics explains the underlying mechanisms: Her astrophysics research focused on neutron star collisions.
