What are the three types of galaxy clusters?

Regular & Irregular Clusters A regular cluster is a cluster that is spherically-shaped, usually rich, and one that contains many elliptical galaxies. An irregular cluster is a cluster with no specific shape, generally poor, and made of irregular, elliptical, spiral, and barred spiral galaxies.

What is the difference between a galaxy group and a galaxy cluster?

A typical galaxy group has around 50 galaxies, and contains a total mass of about 10 trillion times the mass of the Sun. Galaxy clusters are even larger, and can contain up to 1000 galaxies., with a mass of 100 trillion to 1000 trillion suns.

How many galaxys are in the galaxy cluster?

NARRATOR: The universe contains about 100 billion galaxies in gigantic groups called galaxy clusters.

What galaxy super cluster are we in?

The Laniakea supercluster
The Laniakea supercluster, containing the Milky Way (red dot), is home to our Local Group and so… [+] Our location lies on the outskirts of the Virgo Cluster (large white collection near the Milky Way).

What is the difference between an SB galaxy and an Sc galaxy?

Sb galaxies are intermediate. Sc galaxies have small nuclei, lots of gas and dust and many hot, bright stars.

What’s bigger galaxy or galaxy cluster?

Groups and clusters may contain anywhere from three to thousands of galaxies. The smaller aggregates, typically containing less than 50 galaxies each, are referred to as galaxy groups, and the larger aggregates are known as galaxy clusters.

Is a galaxy cluster bigger than a galaxy?

When comparing the two, a typical globular cluster might contain a mass of 100,000 Suns, whereas the Milky Way has nearly 1 trillion solar masses. In other words, the Milky Way Galaxy contains 10 million times more mass than a typical globular cluster.

Are galaxy clusters expanding?

The reason is that in a cluster of galaxies, the mutual gravity between the various galaxies is able to overcome the cosmic expansion and hang on together as a gravitationally bound system. Thus within the cluster, the galaxies will not be expanding away from each other.

Is the Laniakea Supercluster real?

The Laniakea Supercluster (/ˌlæni. əˈkeɪ. ə/; Hawaiian for “open skies” or “immense heaven”) is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies. It was defined in September 2014, when a group of astronomers including R.

How do you categorize galaxies?

Galaxies are classified by shape. There are three general types: elliptical, spiral, and irregular. Perhaps the most familiar kind of galaxy are spiral galaxies. They have a distinctive shape with spiral arms in a relatively flat disk and a central “bulge”.
