  Galaxy - Wikipedia, the free encyclopedia
Most galaxies are several thousand to several hundred thousand light years in diameter and are usually separated from one another by distances on the order of millions of light years.
Clusters of galaxies are often dominated by a single giant elliptical galaxy, which over time tidally destroys its satellite galaxies and adds their mass to its own.
This galaxy rotation problem is thought to be explained by the presence of large quantities of unseen dark matter.

 Galaxy - MSN Encarta
Thousands of galaxies were identified and cataloged by the British astronomers Sir William Herschel, Caroline Herschel, and Sir John Herschel, during the early part of the 19th century.
This was interpreted by the American astronomer Edwin Hubble as evidence that all galaxies are moving away from one another and led to the conclusion that the universe is expanding.
In viewing a galaxy with a telescope, inferring its distance is impossible, for it may be a gigantic galaxy at a large distance or a smaller one closer to Earth.

Galaxies are generally not isolated in space but are often members of small or moderate-size groups, which in turn form large clusters of galaxies.
The most distant galaxies known, near the edge of the observable universe, are faint blue objects called “blue fuzzies” because of their appearance on photographic plates.

Recognition that galaxies are independent star systems outside the Milky Way came from a study of the Andromeda Galaxy (1926-29) by Edwin P. Hubble that indicated the great distances at which this and other galaxies are located.
Harlow Shapley encouraged the exclusive use of the term "galaxies." Billions of galaxies are within the optical range of the largest telescopes; in 1996 analysis of photographs taken from the Hubble Space Telescope increased the estimated number of galaxies from 10 billion to 50 billion.
A typical spiral galaxy is shaped like a flat disk, about 100,000 light-years in diameter, with a central bulge, or nucleus, containing old stars; winding through the disk are the characteristic spiral arms of dust, gas, and young stars (see stellar populations).

Our own galaxy, the Milky Way, sometimes simply called the Galaxy (with uppercase), is a large barred spiral about 30 kiloparsecs or 100,000 light years in diameter, contains about 300 billion stars and has a total mass of about a trillion times the mass of the sun.
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.
Galaxy is also a type of chocolate candy bar made by the Mars company.

 C-5 Galaxy - Wikipedia, the free encyclopedia
Unlike its Russian counterpart, the civilian- and military-operated Antonov An-124 'Condor', use of the C-5 is confined entirely to the military sector.
The Galaxy carries nearly all of the Army's combat equipment, including such bulky items as its 74-ton mobile scissors bridge, from the United States to any theater of combat on the globe.

 Galaxies
Galaxies are large systems of stars and interstellar matter, typically containing several million to some trillion stars, of masses between several million and several trillion times that of our Sun, of an extension of a few thousands to several 100,000s light years, typically separated by millions of light years distance.
The most massive galaxies are giants which are a million times more massive than the lightest: Their mass range is from at most some million times that of our Sun in case of the smallest dwarfs, to several trillion solar masses in case of giants like M87 or M77.
Among the biggest Messier galaxies are the Andromeda galaxy M31 and the bright active Seyfert II galaxy M77.

 Andromeda Galaxy
Andromeda's satellite (or "companion") galaxies include M32 and M110, two bright dwarf elliptical galaxies that are the brightest of a swarm of smaller companions.
Satellite galaxy M32 may be interacting to distort the disk structure of Andromeda itself, whose spiral arms of neutral hydrogen are displaced from those consisted of stars by around 4,000 light-years and so cannot be continuously followed in the area closest to its smaller neighbor.
One hypothesis is that such satellite galaxies are tiny left-overs from the break-up of a more massive galaxy which has since been swallowed by their host but still move within the orbital plane of their predecessor, as galactic mergers are believed to be a main mechanism of galactic growth.

 The Milky Way Galaxy
As a galaxy, the Milky Way is actually a giant, as its mass is probably between 750 billion and one trillion solar masses, and its diameter is about 100,000 light years.
The Milky Way Galaxy belongs to the Local Group, a smaller group of 3 large and over 30 small galaxies, and is the second largest (after the Andromeda Galaxy M31) but perhaps the most massive member of this group.
M31, at about 2.9 million light years, is the nearest large galaxy, but a number of faint galaxies are much closer: Many of the dwarf Local Group members are satellites or companions of the Milky Way.
