Astronomy is the scientific study of celestial objects (like stars, planets, galaxies, nebulae, etc.) and phenomena that originate outside of Earth's atmosphere. It involves observing, analyzing, and interpreting the light and other radiation that comes from these objects to understand their composition, structure, evolution, and motion.
Here are some key areas of astronomy:
* Observational astronomy: This involves using telescopes and other instruments to collect data about celestial objects.
* Theoretical astronomy: This involves using mathematical models and computer simulations to understand the physical processes that govern the universe.
* Astrophysics: This branch of astronomy focuses on the physics of celestial objects and phenomena.
* Cosmology: This branch of astronomy studies the origin, evolution, and large-scale structure of the universe.
