Question

Quizplus · Accepted Answer

The detailed measurements of the disk and central bulge region suggest that our Milky Way is a barred spiral galaxy, which has a distinctive bar-shaped feature in the center of the galaxy. This is supported by observations of the distribution of stars in the galaxy and the motion of gas and dust. While there is some evidence of a central bulge, it does not have the characteristics of an elliptical galaxy. It also does not have the irregular structure or high energy output of a quasar. The detailed measurements suggest that our Milky Way has a bar at the center of the galaxy, which would classify it as a barred spiral galaxy. This is different from a normal spiral galaxy, which does not have a bar in the center. Additionally, there is no evidence to suggest that our galaxy is a very flat elliptical or dusty irregular galaxy, and it is certainly not a quasar.
