The two correct statements that describe elliptical galaxies are:
- They are the most common galaxy type.
- They typically contain very little gas and dust.
Elliptical galaxies do not include the Milky Way, as the Milky Way is classified as a spiral galaxy. Additionally, while elliptical galaxies can be large, they are not solely defined as the largest types of galaxies in the universe, which can also include giant spiral galaxies.
