The Planetarium Science Center is celebrating the Eratosthenes Festivity, which has become an annual tradition that takes place every year on 21 June at the Bibliotheca Alexandrina and the city of Aswan. It is designed for preparatory school students, and includes a series of activities that revolve around the methodology Eratosthenes used in measuring the Earth’s circumference 2000 years ago. On 21 June, the day of summer solstice, the 21st century school students conduct Eratosthenes’ experiment at the BA Plaza and in Aswan (Upper Egypt) to measure the circumference of the earth.

Sciencetival is an international four days’ Science Festival on the bridges, squares and streets of Ljubljana, the capital of Slovenia. It also partly takes place inside the Slovenian Science Centre – Hisa eksperimentov (The House of Experiments) which is also the organiser of the Sciencetival. The target group are all the curious ones – those who are not afraid to admit that they don’t know everything and are willing to learn new facts.

The Planetarium Science Center will celebrate the GLOBE at Night program, which is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure their night sky brightness and submit their observations to a website from a computer or smart phone. The GLOBE at Night campaign has run for two weeks each winter/spring for the last six years. People in 115 countries have contributed 66,000 measurements, making GLOBE at Night one of the most successful light pollution awareness campaigns.

Thirty years have elapsed since ”la Caixa” Foundation’s Science Museum opened its doors in Barcelona.
