Understanding Astronomy

(updated 16 March 2023)

Astronomy is a branch of Physical Science that is concerned with the study of objects and effects in space or regions beyond the Earth’s atmosphere.

I’ve always been interested in space and the stars. I realized that knowledge of Astronomy is important for an understanding of the Universe and even how the Earth was formed.

The purpose of these lessons is to help you gain understanding the basics of Astronomy, such that you will become a champion in the subject.
