The 12th International Cosmic Day will take place on November 21, 2023 at the Physics building.

The International Cosmic Day (ICD) is dedicated to cosmic rays, which constantly surround us but always go unnoticed. So let’s spend a day exploring the world of cosmic rays and discovering what secrets they hold.

On this day, students, teachers and scientists around the world will 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?
