What are the 3 main types of galaxies and their characteristics?
There are three general types: elliptical, spiral, and irregular. Perhaps the most familiar kind of galaxy are spiral galaxies. They have a distinctive shape with spiral arms in a relatively flat disk and a central “bulge”. The bulge has a large concentration of stars.
What are the 3 types of galaxies quizlet?
Galaxies come in three major types: spiral, elliptical, and irregular. * such as our Milky Way, look like flat white disks with yellowish bulges at their centers. The disks are filled with cool gas and dust, interspersed with hotter ionized gas, and usually display beautiful spiral arms.

What are the types of galaxies answer?
There are four main categories of galaxies: elliptical, spiral, barred spiral, and irregular. These types of galaxies are further divided into subcategories while at the same time other types of galaxies exist based on their size and other unique features.
Why are there different types of galaxies?
Explanation: The galaxies that have been undisturbed for billions of years are likely to form spiral, disk shaped galaxies. Smaller galaxies gravitationally attract each other and merge into an elliptical shape. This merging process can go on for billions of years.

What type of galaxy is the Milky Way galaxy?
spiral galaxy
The Milky Way is a huge collection of stars, dust and gas. It’s called a spiral galaxy because if you could view it from the top or bottom, it would look like a spinning pinwheel. The Sun is located on one of the spiral arms, about 25,000 light-years away from the center of the galaxy.
