Religion and astronomy are two topics that are often mixed together but have different ideas. Astronomy is a science that studies stars, planets and the universe. People who study astronomy look for patterns in the sky and use that knowledge to create models of the universe. Religion is a system of beliefs and rituals that people use to explain the world and provide comfort and support. While religion and astronomy can sometimes be related, religion is mainly focused on beliefs and rituals, while astronomy is mainly focused on physical facts and figures.
