| Purpose: This module deals with the physical properties of our Galaxy and the galaxies in the Local Group. We discuss the structure and the components of the Galaxy, and the spatial distribution and the dynamics of the different stellar populations and the interstellar medium. Another important topic is the evolution of stellar populations. The second part of the module deals with the properties of the members of the Local Group. We discuss how the Local Group formed, what kind of galaxies are found today and how they move and interact, and what will happen to the Local Group in the future. |
