Consider the following pairs:

Spiral Galaxy – Andromeda

Barred-spiral Galaxy – Milky Way

Elliptical Galaxy – GN-z11.

Which of the pairs given above is/are correct?

Question

Spiral Galaxy is the most common type of galaxy found throughout the universe. Around 77% of the galaxies observed by man are spiral galaxies. A good example of this type is the Andromeda galaxy.
Majority of spiral galaxies have a bar-like structure called a barred-spiral galaxy. Around two-thirds of spiral galaxies are barred shaped. Our Milky Way galaxy is a barred shaped galaxy.
The rarest type of galaxies is the elliptical double-ringed galaxy. PGC 1000714 is an example.
Irregular galaxies have no definite shape, though they are in constant motion like all other galaxies. The oldest and farthest galaxy ever discovered is an irregular type of galaxy called GN-z11.
Lenticular Galaxies appear like cosmic pancakes, fairly flat and featureless in the night sky. These galaxies can be thought of as the “in between” of spiral and elliptical galaxies.
