Local Group :
The Local Group is a group of more than 20 galaxies to which the Milky Way Galaxy belongs. About half are elliptical galaxies, with the remainder being of the spiral or irregular type.
Local Group
The galaxies which are gravitationally bound to the , including Fornax, the , M31 (Andromeda Galaxy), M32, M33, M101, Small Magellanic Cloud, and 9 dwarf spheroidal galaxies.
The Local Group is actually spread in an approximate volume of ten million light years (sci.astro FAQ, Hartmut Frommert and Christine Kronberg) in diameter. Membership appears to be dynamic and has undergone significant change over time.

A New Local Group Galaxy: The Antlia Dwarf Galaxy
Astronomers in Cambridge have discovered a new member of the Local Group of Galaxies in a region of space previously thought to be devoid of nearby dwarf galaxies.
This shows a graphical representation of where the galaxies in the Local Group are found. The Milky Way is the large yellow dot near the center, while the other two large spirals, Andromeda and Triangulum are found about 1 Mpc away.

Local Group
The Local Group is the galaxy groups and clusters of galaxy that includes our galaxy, the Milky Way. The group comprises over 50 galaxies , with its gravitational center located somewhere between the Milky Way and the Andromeda Galaxy.
The Local Group is very small, when compared to the famous galaxy clusters like those in Virgo and Coma, which span hundreds of millions of light years.
The Local Group and Virgo cluster are part of a larger long, narrow group called the Local SuperCluster, sometimes called the Virgo Supercluster since the Virgo cluster is close to the middle.
In the Local Group, the Milky Way and M31 (the Andromeda Galaxy) are gravitationally bound, and currently approaching each other at high speed.

Cepheids have been measured from the ground throughout the Local Group (which Hubble could do - the astronomer, not the telescope), and can be detected in the M81 and Sculptor groups, and more recently in M101 at a distance of 7 Mpc (Cook, Aaronson, ...
As we look beyond the Local Group, we see more galaxies. Most galaxies form gravitationally-bound groups and clusters, with the remaining galaxies spread out in the field.
These advances enabled accurate study of the nearby galaxies that comprise the "Local Group" (the group of galaxies including our own Milky Way galaxy and our neighbor the Andromeda galaxy).
VIRGO CLUSTER - Largest and nearest galaxy cluster to the Local Group. The Local Group is often considered to lie on the edge of the Virgo cluster. The Virgo Cluster is approximately 16 Mpc distant and spans 8° on the sky.
Our Milky Way Galaxy is in a cluster of galaxies, called the Local Group. It contains other galaxies, such as M31, LMC and SMC. Typically, a cluster of galaxies contains 1000 galaxies within a million parsecs.
Our own galaxy, the Milky Way resides in such a group of about 30 galaxies, named the Local Group. The Local Group contains 3 large spirals: The Milky Way, The Andromeda Galaxy, and M33.
The nearest cluster is the Virgo cluster; the Local Group is an outlying member of the cluster, which contains thousands of galaxies of many types.
The Triangulum Galaxy is a member of the Local Group of galaxies. It is a spiral galaxy some three million light-years away from Earth.
Barnard's galaxy is a member of the Local Group, the archipelago of galaxies that includes our home, the Milky Way, and resides at a distance of about 1.6 million light-years.
Our galaxy is a member of the Local Group, and together with the Andromeda Galaxy dominates it; overall the Local Group contains about 30 galaxies in a space about ten megaparsecs across.
The Local Group of galaxies, the cluster which contains our Milky Way galaxy, is an example of a poor, irregular cluster. Our Local Group contains about 30 galaxies: 3 spirals, 13 irregulars and 15 ellipticals.
Cosmological redshifts become dominant for objects outside our Local Group of galaxies. These redshifts are a result of the stretching of space time, as postulated by general relativity, and not by radial motion.
Our own galaxy is part of a local group that consists of a few large systems and more than twenty smaller ones. Well beyond our local group astronomers know of galaxies that are 13,000 million light years away.
Figure: The Small Magellanic Cloud is an irregular galaxy that is a member of the local group of galaxies. Another irregular local group member is the Large Magellanic Cloud. These galaxies are visible only in the southern hemisphere.
Our own galactic cluster, the Local Group, is about 5 million light-years across and contains about 30 galaxies (the largest of which are the Andromeda galaxy, Triangulum, and our Milky Way).
The Antlia Dwarf seems to be dominated by an old stellar population, similar to what has been found for most other dwarf spheroidal galaxies in the Local Group.

In April 1997 a new member of our Local Group of galaxies was found in Antlia. This spheroidal dwarf galaxy was discovered by research students Alan Whiting and George Hau of Cambridge University.

The Milky Way is the second-largest galaxy (but perhaps the most massive, or "heaviest") in what astronomers call the Local Group. The slightly larger Andromeda Galaxy and many smaller galaxies also populate the group, which spans about 6.
Third ranked in size in our Local Group of galaxies after M 31 and our own, it is still huge, a full degree in the sky, some 50,000 light years, across.

But, according to the second scenario, the Milky Way would have been born some time after a huge region of gas and dust began to condense into our local group of galaxies.

All galaxies (beyond our local group of galaxies) show redshift, which indicates that the Universe as a whole is expanding. Redshift applies to radio waves, and other wavelengths, as well as to light. It is a special case of the Doppler shift.
