The International Cosmic Day took place on November 10, 2021. There was a reason to celebrate: it was the 10th anniversary. We celebrated it with a short video:

The International Cosmic Day (ICD) focuses on the cosmic rays that surround us all the time but are always unnoticed. So let’s explore the world of cosmic rays for one day and discover what secrets they bring.

During this day, students, teachers and scientists come together to talk and learn about cosmic rays. Questions that can be discussed are:

  • What are cosmic particles?
  • Where do they come from?
  • How can they be measured and what can we learn from them?

If you want to be part of this day and plan a program, you can get more information here.

The 10th International Cosmic Day is organized by DESY together with Netzwerk Teilchenwelt, IPPOG, QuarkNet and Fermilab.
