The 5th International Cosmic Day will take place on November 2, 2016.


This event 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.


Have you become interested? Then participate!


The 5th International Cosmic Day is organized by DESY, together with Netzwerk Teilchenwelt, IPPOG, QuarkNet and Fermilab.
