1. Spiral arms
Spiral arms are a major component of the Milky Way galaxy. They are vast, winding structures of gas and stars that extend outward from the galaxy's center. Spiral arms are thought to be the birthplace of new stars, and they are home to a wide variety of astronomical objects, including star clusters, nebulae, and supernovae.
- Structure
Spiral arms are long, narrow structures that wind around the galaxy's center. They are typically a few thousand light-years wide and can extend for tens of thousands of light-years.
- Formation
Spiral arms are thought to be formed by the gravitational interaction between the stars and gas in the galaxy. As the galaxy rotates, the stars and gas move in slightly different directions, creating a spiral pattern.
- Star formation
Spiral arms are the birthplace of new stars. The gas and dust in the arms is compressed by the gravity of the stars, triggering the formation of new stars.
- Astronomical objects
Spiral arms are home to a wide variety of astronomical objects, including star clusters, nebulae, and supernovae. These objects are often found in the arms because they are formed from the gas and dust in the arms.
