The term space science may mean:
- The study of issues specifically related to space travel and space exploration, including space medicine.
- Science performed in outer space (see space research).
- The study of everything in outer space; this is sometimes called astronomy, but more recently astronomy can also be regarded as a division of broader space science, which has grown to include other related fields.
This article describes the third meaning, space science describing all of the various science fields that are concerned with the study of the Universe, generally also meaning "excluding the Earth" and "outside of the Earth's atmosphere".

Divisions of space science
[edit]
By subject
- Stellar astronomy - the study of stars
- Solar astronomy - the study of our Sun
- Planetary science - the study of planets, especially those other than Earth
- Galactic astronomy - the study of our Milky Way Galaxy
- Extragalactic astronomy - the study of the larger universe beyond the Milky Way
- Physical cosmology - the study of the origin, large-scale structure, and space-time relationships of the universe
See astronomical object for a list of specific types of entities which scientists study. See Earth's location in the universe for an orientation.
