The Planetarium Science Centre (PSC) is a department in the Bibliotheca Alexandrina located in Alexandria, Egypt.

Eratosthenes is an annual festival that the Bibliotheca Alexandrina organizes to promote science and heritage among school students.

The Festivities of 2003–2008 evolved around measuring the Earth's circumference, inspired by the Greek mathematician and poet Eratosthenes.

It discusses topics such as how the Ancient Egyptians built observatories to study astronomy and what their legacy is to modern science.
