- evolution - the evolution of the Milky Way
- formation - the formation of the Milky Way
- fundamental parameters - the fundamental parameters of the Milky Way (mass, size etc.)
- globular clusters - globular clusters within the Milky Way
- halo - the large halo around the Milky Way
- kinematics and dynamics - the motions of stars and clusters
- nucleus - the region around the black hole at the center of the Milky Way (Sagittarius A*)
