The massive Virgo Cluster of 2000 galaxies is approximately 65 million light years distant. The proximity of approximately 50 adjacent tiny groupings of galaxies to the Virgo cluster implies that they together form a massive flattened cluster of clusters, which we name the Local Supercluster. It contains hundreds of smaller clusters and groups of galaxies.
The Virgo Cluster is the largest concentration of galaxies in the local universe. It consists of 13 separate sub-units known as "majors", with more than 30 smaller satellite systems attached. The Milky Way Galaxy is one of the many billions of stars in the Virgo Cluster. It is one of the nearest large galaxy clusters to the Earth at only about 160,000 light years away.
The Hubble Space Telescope has revealed that the Virgo Cluster is not only huge but also contains a huge amount of dark matter. Calculations show that if the cluster was made up entirely of normal matter, then it would be about 100 times larger than it is now. The Hubble data indicate that there is much more mass in the form of dark energy or cosmic inflationary gas than can be accounted for by the visible matter such as stars and interstellar gas.
The Virgo Cluster is our closest large-scale structure to home. It forms a wall along most of the horizon in every direction from our local neighborhood beyond the Milky Way Galaxy.
The Virgo Supercluster encompasses smaller groups and clusters of galaxies, including the Local Group, and is centered on the Virgo Cluster of galaxies around 65 million light-years distant. It is one of the largest structures in the Universe.
The Virgo Supercluster has a total mass estimated at about 5 times that of the Milky Way Galaxy. If the Virgo Supercluster were a single galaxy, it would be among the most massive galaxies known with a stellar mass greater than 2×1011 M⊙ and a dark matter mass more than 3×1012 M⊙.
Galaxies are the building blocks of structured matter in the Universe. The stars within galaxies come in two main types: red giants and blue stars. Galaxies can be divided up by their predominant type of star they contain: spiral galaxies like our own, or elliptical galaxies such as Andromeda.
Stars are not isolated objects but instead form in groups or associations called open clusters or stellar systems. Our Sun is part of an open cluster called the Pleiades, which contains hundreds of stars with similar ages as ours. Spiral galaxies like ours contain many stellar systems called globular clusters which are large aggregates of stars formed from gas clouds that failed to collapse into individual planets.
Hundreds of galaxies can be found in larger clusters of galaxies. The density of massive galaxies in the Virgo Cluster is approximately 10 times that of the Local Group. The Virgo Cluster's immense gravity causes it to be at the heart of a bigger formation known as the Local Supercluster. This vast structure contains hundreds of smaller clusters like the Virgo Cluster that are all separated from each other by empty space.
In conclusion, the Virgo Cluster is a rich cluster of galaxies with a mass about equal to half that of our Milky Way Galaxy. It is located in the constellation Virgo (the Virgin).
A word used to describe any particularly huge, prolonged cluster of galaxies. A name used to describe the Virgo Cluster of galaxies and its satellite galaxies, including the Local Cluster. Is a reference to the supergalactic coordinate system's structure. Brightest galaxy cluster A huge galaxy (also known as a giant elliptical galaxy, gE, cD, or D), see galaxy. It has a very large mass of stars and an equally massive black hole at its center. Most have hundreds of thousands or even millions of stars in their nuclei.
The Virgo Cluster is the largest concentration of galaxies in the Universe. It contains about 150 members, with more than half of them being dwarf galaxies. The remaining ones are giant ellipticals like our Milky Way Galaxy. The average distance between galaxies within the cluster is about 100 million light years. Its size can be estimated by counting all its members: it covers an area of about 50,000 square miles or less than 1/10th of a single galaxy! The Virgo Cluster is located near the constellation Virgo at a distance of about 26 million light years from Earth.
The term "cluster" comes from the Latin word meaning "collection". Thus, a cluster of galaxies is just like many other collections of objects: a bunch of grapes, a flock of birds, etc. Only in this case, the object being collected is galaxies. Galaxies are large aggregates of stars that form along with other matter in the space between dark matter halos around distant clusters of galaxies.
