Question

What is the shape of the milky way galaxy?
A. Circular
B. Spiral
C. Elliptical
D. Irregular

Answer 1

Hint: The galaxy appears as a milky band of light in the sky, that's why it is called the milky way galaxy. The Milky Way galaxy is the home galaxy of our planet.

Complete answer:
A galaxy is a system of million stars consisting of gas and dust which are bound by each other through gravitational force. Besides our milky way galaxy which is known as Sagittarius A, there are millions and millions of galaxies in the universe.. The giant clouds of gas and dust with star clusters form the spiral arm of the milky way galaxy. Some parts of the galaxy are also made up of dark matter. Our galaxy consists of four spiral arms that emerge from the central bar. The Milky way galaxy is of barrel spiral shape. The stars that are visible at night from naked eyes are included in it. The band appears to be the disk of stars which forms the milky way inside of the disk that means our galaxy is originally flat and the concentration of stars in the bands forms the spiral shape of our galaxy
The huge and large collection of gas, dust, millions of stars, and their solar systems all appear together due to gravitational attraction in the galaxy. There are four types of galaxies.
1. Spiral Galaxies
2. Lenticular Galaxies
3. Elliptical Galaxies
4. Irregular Galaxies
So, the correct answer is Option A.

Note: All the stars we observe at night are in our milky way galaxy that comes from the bright band of stars. The supercluster of galaxies now is also called Tanaka, meaning immense heaven. To know about the Concepts, types, and the difference between different types of galaxies are necessary.
