Cosmic Rays in the Milky Way and Beyond

Abstract
Cosmic rays (CRs) are the probes of the deep space. They allow us to study particle acceleration, chemical composition of the interstellar medium, and global properties of our Galaxy. However, until recently studies of CRs were similar to astronomical observations with blurred lenses that capture only the integral brightness of all stars in the field of view. Thanks to the recent technological developments, our "lenses" are now capable of capturing sharp images and making precise measurements of all CR species. We have a full range of unique instrumentation for direct measurements of CRs in space and for multi-wavelength observations of their emissions and more missions are coming. The unveiling picture is astonishing. This paper gives a short overview of very exciting developments in astrophysics of CRs in the Milky Way and in other star-forming galaxies.
