Each participating group will plan its own event. Events may include activities such as cosmic particle discussions, news about the latest research, or even direct measurement and/or data analysis of cosmic particles. The following formats can be used:

  • Lectures
  • Masterclasses or Masterclasses@home
  • Video broadcast to the classroom
  • Assignments that students can complete at school or at home

On this page you will find some ideas for different activities for your event. We will also announce events that all people from around the world can attend, such as lectures via livestream. Feel free to suggest activities as well. There are no limits to your ideas.

At the end of the day, it would be great if you could summarize your work during the day and your findings on cosmic rays in a proceeding (see Organization). We will include your contribution in a booklet and make it available to all participants.


Welcome Call

As every year, there was a welcome from headquarters. We are pleased to welcome guests to the Welcome Call again this year. You can watch the recording of the Welcome Call here:

Video Calls

We organize video calls where groups can share their results and findings. In the video calls, students can present their results to each other, ask each other questions, and discuss new findings. For more information, see the organizers section (Registration required for access).

Online Introductions

We are pleased to offer online lectures on cosmic rays. In these videos we explain...

We also offer different types of data analysis for different tools and projects:

Data Analysis with Cosmic@Web

On the Cosmic@Web learning platform, we make public cosmic-ray data available, along with background information, descriptions of the experiments, explanations of the data sets, and hints on how to interpret them. For more details, see the Cosmic@Web tutorial. Also take a look at our contribution to the 36th and 37th International Cosmic Ray Conferences:

And check out the Cosmic@Web video from 2021:

Data Analysis by OCRA

The INFN OCRA collaboration provides a series of online activities for cosmic ray data analysis on its webpage (only available in Italian): After an introduction on various techniques for the detection of cosmic rays with experiments on the Earth, a laboratory section offers the possibility to analyse the data of real experiments, from educational activities like a cosmic ray telescope located in a Naples metro station to data from experiments dedicated to frontier research, like the Auger observatory in the Argentinian pampa.

Data Analysis by EEE Project

For this edition of the ICD, the EEE Project has prepared an online meeting during which, together with presentations by researchers engaged in the study of cosmic rays, students will be able to present the results of the analyses. In particular, we propose to students to study the variation of the cosmic ray flux as a function of the direction of arrival:

Data Analysis with KCDC

KCDC (KASCADE Cosmic Ray Data Centre) is a public data centre for high-energy astroparticle physics based on the data of the KASCADE experiment. KCDC offers a wide range of resources, including the outreach ones. The tutorials and examples at KCDC’s website represent a compilation of interesting lessons within the vast field of cosmic radiation to illustrate the processes within and outside of our atmosphere by means of the data sets of the KASCADE experiment. On the KCDC's JupyterLab one can find some tutorials, based on KASCADE, TRVO and and IceCube data samples. For more details, see the KCDC analysis instruction:

In between, get creative with one of our contests and take part in a Kahoot! quiz:

Drawing contest

Draw your favorite cosmic particle. Post it on Facebook or Instagram and use the hashtag #InternationalCosmicDay. The best one will get a prize!

Selfie contest

Take a selfie of you with your detector or your favorite Cosmic Ray plot. Post it on Facebook or Instagram and use the hashtag #InternationalCosmicDay. The best one will get a prize!
For inspiration, the photo that won in 2019: a group from INFN Gran Sasso:


As every year, we will again offer a quiz. On the day of the ICD, November 22, 2022, we will publish here the access code for the Kahoot. Test your knowledge against opponents worldwide!


As at a real scientific conference, all contributions will be documented in writing afterwards. Write your proceeding about your work and results on cosmic rays. We will bundle all proceedings in a booklet and make it available to you. More information will be available after Registration.
