The Milky Way Galaxy is composed of multiple complex celestial structures.
The overall structure consists of the Galactic Core, Galactic Disk, Galactic Halo, and globular clusters, among others.
The Galactic Core is the center of the Milky Way Galaxy, containing a large number of stars, gases, dust, etc.
This is the densest and richest region of the Milky Way Galaxy.
The mass of the Galactic Core is about four million times that of the Sun, with a radius of about ten light-years.
The Galactic Disk is the main part of the Milky Way Galaxy, containing most of the stars, gases, and dust.
The Galactic Disk is flat, with a thickness of about two thousand light-years.
The stars within the Galactic Disk are distributed unevenly; some regions have dense stars, while others are relatively sparse.
Regions with dense stars often indicate rich resources, which may be more favorable for the development of life and civilization.
