Astronomy in the Medieval Islamic world was a very important part of life. Astronomers studied the stars, planets, and other objects in the sky to create maps and help people tell time and navigate the world. They did this by using complex math, as well as observational instruments. Astronomers in the Medieval Islamic world also contributed to other fields, like medicine, architecture, and literature. By looking at the stars, they were able to make predictions about the weather, understand movements of stars and planets, and even the distant planets in our solar system. They were also strongly influenced by the philosophies of ancient Greek and Indian astronomers, learning from them and making their own observations to add new knowledge to the field.
