Whenever you learn about the stars, planets, or space, you are engaging in the branch of science known as astronomy. Astronomy is the study of the universe, and that includes all objects in space as well as all the phenomena happening in space.
You can learn about astronomy through books, clubs, or classes in school. However, some books and classes can be expensive or hard to come by. Online courses are a great alternative to learn any subject, including astronomy!
Online astronomy classes are easily accessible. You need access to a computer and the internet. They are also convenient because you can take most of them when you have the time and/or focus on completing them. Online astronomy courses help you learn more about the universe in a manner that is more convenient for you and your education.
If you are unsure where to look, here are some great online courses for beginners regarding different topics in astronomy.
