The International Cosmic Day will bring students, teachers and scientists together to talk and learn about Cosmic Rays.

What are cosmic particles?
Where do they come from?
How can they be measured?
During the International Cosmic Day (ICD) you will find answers to these questions. But furthermore, you will carry out your own measurements and get in contact with groups all over the world to compare and discuss your results. You will work like a real scientist in an international collaboration.
