Here's an overview of its key characteristics: 1. **Structure**: The Milky Way is a barred spiral galaxy, meaning it has a central bar-shaped structure surrounded by spiral arms. It is estimated to have a diameter of about 100,000 to 120,000 light-years. 2. **Components**: The Milky Way consists of several main components: - **Galactic Center**: At the core of the Milky Way lies a dense region known as the galactic bulge, which contains a supermassive black hole called Sagittarius A*. - **Spiral Arms**: Spiral arms extend outward from the galactic center, containing a mix of stars, gas, and dust.
