On November 30th was the 6th International Cosmic Day.


Professor Antonino Zichichi had a message for all the participating groups, with great thanks to the EEE-groups from Italy and CERN:

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.


Also this year, scientists from the two renowned collaborations ATLAS and IceCube will present their data regarding the questions addressed by the International Cosmic Day during the international exchange.

ATLAS is a high-energy experiment at the Large Hadron Collider at CERN and focuses on the investigation of the fundamental forces of nature. To achieve this, protons are accelerated and collided to measure the resulting particles.

The astroparticle physics experiment IceCube detects the elusive neutrinos from far-away sources. It explores the physics of exploding stars, gamma-ray bursts, and other origins of high-energy neutrinos.

While both experiments follow different aims, they both also detect the ever-present muon and can contribute results to the International Cosmic Day.


Are you interested? Then participate. Also have a look at our contribution to the 35th International Cosmic Ray Conference (ICRC2017_poster_web.pdf (PDF, 1.3 MB), Proceeding.pdf).


The 6th International Cosmic Day is organized by DESY together with Netzwerk Teilchenwelt, IPPOG, QuarkNet and Fermilab.
