What is called Virgo cluster?
The Virgo Cluster is the closest and best-studied great cluster of galaxies, lying at a distance of approximately 20 Mpc in the constellation of Virgo. Cosmographically, the Virgo Cluster is the nucleus of the Local Supercluster of galaxies, in whose outskirts we (in the Milky Way, in the Local Group) are situated.

Is there life in the Virgo cluster?
The Milky Way sits near the middle of an assembly of galaxies called the Local Group. This gathering, 10 million light-years wide, lives on the edge of a collection of galaxy clumps called the Local, or Virgo, Supercluster.
Is the Virgo cluster gravitationally bound?
They belong to galaxy groups within our larger Local Supercluster. As detection and analysis techniques improved, however, astronomers realized the Virgo Supercluster was not a gravitationally bound object.
What is the Virgo cluster made up of?
The cluster is an aggregate of at least three separate subclumps: Virgo A, centered on M87, a second centered on the galaxy M86, and Virgo B, centered on M49, with some authors including a Virgo C subcluster, centered on the galaxy M60 as well as a LVC (Low Velocity Cloud) subclump, centered on the large spiral galaxy …
How fast is the Virgo cluster moving?
about 400 km/s
Our Supercluster, with a diameter measuring roughly 100 million light years or so, has a collective mass of about 1015 times the mass of the Sun. The Local Group, which is near one edge of the Local Supercluster, appears to be revolving around its center at about 400 km/s.
What is the Virgo cluster made of?
Of all of the subclumps, Virgo A, formed by a mixture of elliptical, lenticular, and (usually) gas-poor spiral galaxies, is the dominant one, with a mass of approximately 1014 M ☉, which is approximately an order of magnitude larger than the other two subclumps.
How fast is the Virgo Cluster moving?
Is Earth in the Virgo Supercluster?
There’s really nothing bigger in the Universe. The supercluster we live in is known as the Virgo Supercluster. It’s an enormous collection of more than a million galaxies, stretching across a region of space 110 million light-years across.
Is Earth in the Virgo supercluster?
How big is the mass of the Virgo Cluster?
The Local Group actually experiences the mass of the Virgo Supercluster as the Virgocentric flow. It is estimated that the Virgo Cluster’s mass is 1.2 × 10 15 M☉ out to 8 degrees of the cluster’s center or a radius of about 2.2 Mpc.
Where is the center of the Virgo Supercluster?
The Virgo Cluster, which sits 65 million light-years away, is near the center of our Local Supercluster; their coincident positions are why it is called the Virgo Supercluster.
How many galaxies are in the Virgo Supercluster?
Our local supercluster spans 10 times the diameter of the Local Group, gathering smaller groups and clusters of galaxies together into a galactic megacity. Over 700 galaxies appear in this image of the Virgo Cluster, including the string of galaxies known as Markarian’s Chain at the center of the field.
Is the Virgo Cluster a dynamically young cluster?
This strongly suggests the Virgo cluster is a dynamically young cluster that is still forming. Other two nearby aggregations known as M Cloud, W Cloud, and W’ Cloud seem to be background systems independent of the main cluster.
