Question

The Shape of a galaxy which is longer in only one direction and is more rounded is called:
A. Spiral shape galaxy
B. Irregular shape galaxy
C. Elliptical shape galaxy
D. Regular shape galaxy

Answer 1

Hint: An elliptical galaxy is a form of galaxy having an elliptical shape and a smooth, practically featureless appearance. They are most commonly seen around the centres of galaxy clusters. Elliptical galaxies range in size from tens of millions to billions of stars.

Complete answer:
Elliptical galaxies are the most common type of galaxies discovered in the cosmos, although due to their age and dimness, they are frequently outshone by younger, brighter star clusters.
Elliptical galaxy is a galaxy with an ellipsoidal shape (stretched circles). Elliptical galaxies lack the spiralling arms of their more famous siblings, spiral galaxies. They have the rounded shape of an ellipse, which is a stretched-out circle.
Elliptical galaxies have a reddish to yellowish tint due to the presence of predominantly ancient stars. Because they have already formed, most elliptical galaxies contain relatively little gas and dust. Some elliptical galaxies, on the other hand, have a lot of dust.
Hence, the correct option is: (C) Elliptical shape galaxy

Note:
Scientists believe that elliptical galaxies are nearing the end of the evolutionary line for galaxies since they contain older stars and less gas. Collisions between galaxies are common in the universe, and the Milky Way is slated to collide with the Andromeda Galaxy in a few billion years.
