space science

Study of cosmos

Space science is the study of phenomena beyond Earth's atmosphere—planets, stars, galaxies, and the physical conditions of outer space.

The term encompasses astronomy, astrophysics, planetary science, and related fields: She pursued a degree in space science.

It often implies research connected to spaceflight and exploration rather than purely theoretical work.
