These galaxies are made up of stars, gas and dust held together by gravitational forces. Each galaxy type is named for its shape, making it easy to identify the type of galaxy under consideration. You may already be familiar with galaxies: spirals, striped, elliptical and irregular spirals.
What 4 types of galaxies are there?
In 1936, Hubble pioneered a method of classifying galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies.
What 5 types of galaxies are there?
There are four main categories of galaxies: elliptical, spiral, barred spiral, and irregular. Read on for even more facts and information. Galaxies are classified into ellipses, spirals, barred spirals, or irregular galaxies based on their visual morphology. They are sometimes divided into subcategories.
How many types of galaxies are there?
The galaxies are classified by shape. There are three general types: elliptical, spiral, and irregular. Spiral galaxies are perhaps the best known galaxies.
What 3 types of galaxies are there?
What types of galaxies are there? Astronomers classify galaxies into three broad categories: elliptical, spiral, and irregular. These galaxies range in size from dwarf galaxies with just 100 million stars to giant galaxies with over a trillion stars.
What types of galaxies are there?
Astronomers classify galaxies into three broad categories: elliptical, spiral, and irregular. These galaxies range in size from dwarf galaxies with just 100 million stars to giant galaxies with over a trillion stars.

What are the 4 types of galaxy classification?
Edwin Hubble invented a classification of galaxies and grouped them into four classes: spirals, barred spirals, elliptical, and irregular galaxies. He then classified spiral and barred spiral galaxies according to the size of their central bulge and the texture of their arms.

What is the difference between a barred spiral galaxy and a normal spiral galaxy?
Spiral galaxies Normal spirals have arms radiating from the nucleus, while barred spirals have a bright linear feature called a bar that overlaps the nucleus, with the arms unwinding at the ends of the bar.
