What are the differences between the 3 types of galaxies?

What are the differences between the 3 types of galaxies?

Spiral galaxies are mostly large, elliptical are mostly small in size. The most famous irregular galaxies can be seen with the unaided eye. Irregular galaxies generally have young stars, elliptical galaxies have old stars, and spiral galaxies have both young and old stars.

What are the 3 biggest galaxies?

The three largest members of the group are our Milky Way (second-biggest), the Andromeda galaxy (biggest), and the Triangulum Galaxy. The other galaxies in the Local Group are dwarf galaxies, and they’re mostly clustered around the three larger galaxies.

Why there are different types of galaxies?

Explanation: The galaxies that have been undisturbed for billions of years are likely to form spiral, disk shaped galaxies. Smaller galaxies gravitationally attract each other and merge into an elliptical shape. So the galaxy seems irregular in shape in between a merging process.

Why there are different kinds of galaxies?

What are the three main types of galaxies?

What Are The 3 Types Of Galaxies [Full Guide] 1 1. Spiral Galaxies. The three main components that make up a spiral galaxy are the center called bulge, the disk that makes the arms and the last part 2 2. Elliptical Galaxies. 3 3. Irregular Galaxies.

Which is younger spiral galaxies or elliptical galaxies?

Scientists believe that spiral galaxies are younger than elliptical galaxies. It’s thought that spiral galaxies burn through the star-forming fuel and eventually become elliptical galaxies. The Hubble classification scheme uses the letter “E” to identify elliptical galaxies.

Which is an example of an irregular galaxy?

Irregular Galaxies Irregular galaxies are as their name suggests: irregular in shape. The best example of an irregular that can be seen from Earth is the Small Magellanic Cloud. Irregulars usually do not have enough structure to characterise them as spirals or ellipticals.

Which is an example of a giant galaxy?

Some examples of a giant galaxy is the ESO 325-G004 followed by an example of a medium-sized galaxy, the Leo I and a much smaller elliptical galaxy are the M110 and the M32. All of these fall under the Andromeda as found out by Hubble. 3. Irregular Galaxies
