What does astronomy mean? A dictionary will tell you that it’s the branch of science that deals with celestial objects, space, and the physical universe as a whole. Astronomy is the study of everything in the universe that’s beyond our own planet’s atmosphere.
What science is astronomy part of?
Astronomy (from Greek: ἀστρονομία, literally meaning the science that studies the laws of the stars) is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution.
What field does astronomy fall under?
Astronomy is generally recognized as a sub-field within physics. In order to be successful in this field a student must be very strong in physics, mathematics and the sciences, generally.
Is astronomy part of chemistry?
There is actually quite a lot of Chemistry used in various areas of Astronomy. One big application is in the identification of spectral lines. … Spectral lines are a fundamental consequence of chemistry, but are also the primary tool that Astronomers use to learn about the chemical makeup of distant objects.

- ASTROPHYSICS: Applying the laws of physics in space.
- ASTROMETRY: Mapping celestial bodies.
- ASTROGEOLOGY: Examining rocks, terrain and material in space.
