The International Cosmic Day is just around the corner!

On November 13, 2025, students, teachers, and scientists around the world are invited to explore cosmic particles together. In video calls, young researchers can exchange their results, and a drawing and selfie contest will challenge the creative minds.

This is a great opportunity to inspire your students with astroparticle physics. You can either take part with your own cosmic experiment or carry out an analysis via Cosmic@Web. Instructions and further information about all activities can be found here: https://icd.desy.de/activities/.

The registration deadline is October 30, 2025!
