How to become an astronomy teacher
Develop your own love for astronomy.
Although astronomy, by its nature, is a fascinating science, you need to discover and develop this fascination for yourself before you can teach it to others. It is helpful to develop a love for astronomy as early in your life as you can, although it can also be a love you discover in early adulthood or later in life.
There are several ways you can nurture this fascination for yourself at any age. Studying the night sky for yourself is the surest way to discover the wonders of the universe.
