To what cluster of galaxies does the Milky Way Galaxy belong?
It belongs to the Local Group of Galaxies which contains about 20 galaxies including the Milky Way Galaxy, the Andromeda galaxy and the two Magellanic Clouds.
How many galaxies are there in a cluster of galaxies?
Galaxies tend to form clusters containing up to a few thousand galaxies. The Local Groups of Galaxies is a relatively small cluster of galaxies.
Are galactic clusters visible to the naked eye?
Yes. The Pleiades and the Hyades are examples of galactic clusters visible to the naked eye.
How did galactic clusters originate?
Galactic clusters are thought to have originated from the fragmentation of large gas into smaller gas clouds which in turn have formed stars. All galaxies in a galactic cluster may therefore be assumed to be of the same age. Most galactic clusters are relatively young, perhaps a few tens or hundreds of millions of years pls.
To what super cluster of galaxies does the Local Group of Galaxies belong?
The Local Group of Galaxies belongs to the Virgo Super Cluster of Galaxies containing thousands of galaxies.
