- ASTHROPHYSICS: Application of the laws of physics in space.
- ASTROMETRY: mapping of celestial bodies.
- ASTROGEOLOGY: Exploration of rocks, landscape and material in space.
- ASTROBIOLOGY: The Search for Life Abroad.
What are the 2 types of astronomy? Around the last century, astronomy has been broadly divided into two camps: observational astronomy (using telescopes and cameras to collect data about the night sky) and theoretical astronomy (using this data to analyze, model, and theorize how objects and phenomena work).

What is an example of astronomy?
Astronomy is the study of extraterrestrial objects and phenomena, while cosmology is the branch of astronomy that studies the origin of the universe and its evolution. See the article : How does astronomy affect our lives. For example, the big bang, the origin of the chemical elements, and the cosmic microwave background are all topics in cosmology.
How is astronomy used in everyday life? The fruits of astronomical science and technological development, especially in areas such as optics and electronics, have become important in our daily lives, using applications such as personal computers, communications satellites, mobile phones, global positioning systems, solar panels. and magnetic resonance …
What are the 2 types of astronomy?
There are two main branches of astronomy: optical astronomy (the study of celestial objects in the visible band) and non-optical astronomy (the use of instruments to study objects in radio using the wavelengths of gamma radiation). See the article : What do you learn in astronomy class.
