More Information

Spiral galaxies are not only one of the most aesthetically pleasing due to their swirling arm structures, but they also play a crucial role in star formation due to their rich gas and dust content. The Milky Way, our home galaxy, is a perfect example of a barred spiral galaxy.

Tips

A common mistake is confusing spiral galaxies with elliptical or irregular galaxies by their shapes. Spiral galaxies have distinct arms and are typically more structured.
