Abstract

This paper gives an overview of the three basic constituents of the interstellar medium (ISM) of our Galaxy, namely, the ordinary matter (made of gas and dust), magnetic fields, and cosmic rays. Without going into any detail, it presents their observed physical characteristics as well as their spatial distributions at large and small scales.
