astrophysicist
Celestial physics expert
An astrophysicist is a scientist who studies the physical properties and behavior of celestial objects—stars, planets, galaxies, black holes.
Where astronomers observe and catalog, astrophysicists apply physics to explain how these objects form, evolve, and interact: She's an astrophysicist studying neutron stars.
The field spans everything from the life cycle of stars to the origins of the universe.
