Star Charts used for Astronomy lessons.

Astronomy is one of the seven compulsory subjects at Hogwarts School of Witchcraft and Wizardry.

During the books, it is taught by Professor Sinistra. Class was held on Wednesday nights at midnight, on the Astronomy Tower. Every student needed their own telescope. The students usually study the night sky and learn the stars names through their observations.

All first-years at Hogwarts must take seven subjects: Transfiguration, Charms, Potions, History of Magic, Defence Against the Dark Arts, Astronomy and Herbology. Flying lessons (on broomsticks) are also compulsory.

At the end of their second year at Hogwarts, students are required to choose a minimum of two more subjects from the following list: Arithmancy, Muggle Studies, Divination, Study of Ancient Runes and Care of Magical Creatures.

Very specialised subjects such as Alchemy are sometimes offered in the final two years, if there is sufficient demand.
