I WONDER - Are There Different Types of Galaxies?

The video discusses the Milky Way as a spiral galaxy, characterized by arms spiraling around a center with new stars at the ends. It introduces three other galaxy types: barred spiral, which has a long center; elliptical, a large star cluster shaped like a disk; and irregular galaxies, often formed by merging galaxies. The video concludes with a light-hearted comment about chocolate.

What is the shape of a typical spiral galaxy like the Milky Way?

• A random assortment of stars

• A large spherical cluster

• A few arms spiraling around a center

• A long bar with no arms

Where are the newest stars typically found in a spiral galaxy?

• On the ends of the arms

• Scattered throughout the galaxy

• In the middle of the arms

• At the center

How does a barred spiral galaxy differ from a regular spiral galaxy?

• It is irregular in shape

• It is shaped like a disk

• It has no arms

• It has a long center instead of a spherical one

What is the shape of an elliptical galaxy?

• A long bar with no arms

• A random assortment of stars

• A few arms spiraling around a center

• A big cluster of stars in the shape of a disk

How are irregular galaxies typically formed?

• From two galaxies merging

• By the collision of asteroids

• By the collapse of a star

• Through the explosion of a supernova
