The main morphological types of galaxies are elliptical, spiral, and irregular.

Based on their morphology , galaxies have been classified into 3 types namely elliptical, spiral, and irregular.

These galaxies have various sizes and shapes ranging from dwarf galaxies to giant galaxies.

Elliptical Galaxy:

  • The shape of it is generally circular
  • These are the largest among all the types of galaxies because according to astronomers, it is formed by the merger of other small galaxies.
  • Their rotational pattern is symmetric.

Spiral Galaxy:

  • A spiral galaxy consists of a bright nucleus surrounded by a thin outer disk forming a spiral shape.
  • This type of galaxy is the most common in our universe.
  • It is divided into three classes: Spiral a, Spiral b, and Spiral c.
  • Their rotational pattern has circular symmetry.

Irregular Galaxy:

  • These types of galaxies have no central nucleus and irregular arms which are bluish.
  • They don’t have any rotational symmetry.
