You should start by learning about the history of astronomy, and the different types of telescopes that have been used throughout history. Then you should learn about the various celestial bodies that astronomers study, such as stars, planets, galaxies, and nebulae. Finally, it would be beneficial to research some of the current astronomical topics being studied today, like dark matter, black holes, and exoplanets.
