What are the 4 types of astronomy?

We can divide astronomy into 4 sub-fields:

  • ASTROPHYSICS: Applying the laws of physics in space.
  • ASTROMETRY: Mapping celestial bodies.
  • ASTROGEOLOGY: Examining rocks, terrain and material in space.
  • ASTROBIOLOGY: Searching for life outside Earth.

How does astronomy differ from lab science?

Explanation: In some scientific fields like chemistry, physics, and biology, evidence often comes from experiments in a laboratory. In astronomy, where many objects are very remote, most of the evidence comes in the form of light and other types of electromagnetic radiation.
