Cosmic radiation - shower of particles from space
- Brötchen-und-Borussia

Cosmic rays are a phenomenon that has fascinated scientists for over a century. It involves particles that hit Earth from space and trigger a variety of processes in the atmosphere. Although their origin is not fully understood, researchers agree that these particles come from a variety of sources, including supernova explosions, neutron stars and black holes.
Cosmic rays are made up of different types of particles, including protons, helium nuclei, and heavier ions. These particles reach energies millions of times higher than those that can be achieved in terrestrial particle accelerators. Once they enter the atmosphere, they collide with gas molecules and create a cascade of secondary particles that propagate to the ground and can be measured by detectors on Earth.
Together we will embark on an exciting journey, from the origin of cosmic rays to their detection with the latest telescopes here on Earth!
![3D visualisation of human neuronal tissue reconstructed by multi-scale X-ray phase contrast tomography. Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
