"Barred" spiral galaxies are called that because

• they have very little material at the center.

• they are really elliptical in shape.

• they have a massive bar of material at the center.

• of massive supernovae explosions near the center.

Elliptical galaxies can be described as having

• no spiral arms and mostly very old stars.

• a circular or elongated shape.

• some spiral structure with lots of gas & dust.

• an irregular shape with mostly old stars.

Spiral galaxies also contain massive lanes of gas & dust which leads to

• supermassive black holes.

• quasars.

• large regions of new star formation.

• aliens.

Irregular galaxies are defined as having

• very little star formation.

• no real shape and are comparatively very small.

• no star formation

• supermassive black holes.

What type of galaxy is pictured?

• E0

• E2

• E4

• E6
