Generally, the galaxies that are further away will have the larger red shifts.

What cosmic accident is believed to form many irregularly shaped galaxies?
Scientist believe the galaxies known as irregular galaxies are the result of several different outcomes, for instance the merger of a pair of galaxies, or a wondering galaxy that strays to close to a neighboring galaxy. There are many different explanations for why irregular galaxies occur.
Why is Andromeda galaxy approaching the milky way galaxy if the universe is expanding exponentially and every thing is supose to be moving further apart due to the expansion of space?
Not everything is moving away from us. The farther an object is away from us, the greater the affect of the expansion. At the distances within galaxy clusters the effects of expanding space are rather small. It is only galaxies in other clusters that are moving away from us. In terms of intergalactic space, the Andromeda galaxy is very close to us, so any effects of cosmic expansion are negligible. At such a distance, the gravitational attraction between the two galaxies has a much stronger influence.
How can scientists calculate the age of the universe using red shift?
The basic idea is to extrapolate the movement of galaxies into the past: at a certain moment, they were very close together.
Is a galaxy a large group of stars?
Yes. The smallest galaxies may contain just a few million stars. Large galaxies like our own, the Milky Way, contain between 200 and 400 billion stars. The largest galaxies are Ellipticals, and may contain as many as 50 trillion stars.
Is Andromeda galaxy the biggest galaxy?
Although the Andromeda Galaxy is a bit larger than the Milky Way, and is large as spiral galaxies go, it is not the largest galaxy. There are larger spiral galaxies, and much, MUCH larger elliptical galaxies. However, because it is relatively close to the Milky Way, the Andromeda Galaxy _appears_ quite large, spanning an apparent width roughly six times that of a full Moon. Still, there are two smaller, closer galaxies (the Magellanic Clouds) which appear larger still. (The Magellanic Clouds are not visible from northern latitudes, however, so one could argue that the Andromeda Galaxy is the biggest galaxy in _apparent size_ visible from most of the northern hemisphere.)
What type of galaxies are close companions of another galaxy?
spril
Are some background galaxies invisible due to being close to a bright foreground galaxy?
Yes. Some background galaxies are invisible due to being close to a bright foreground galaxy.
Are some faint background galaxies masked out due to being close to a bright foreground galaxy?
Yes. Some faint background galaxies are masked out due to being close to a bright foreground galaxy.
How do you use Local Group in a sentence?
We are part of the Local Group. The Local Group contains the Milky Way, two other major galaxies, and dozens of dwarf galaxies. The Local Groups is a group of galaxies which, as galaxies go, are close to us.
Are the galaxies close to each other?
yes, depending on which ones
How many galaxies like your own would it take laid edge to edge to reach the nearest galaxy?
About one. Our galaxy is surrounded by several dwarf galaxies, that are extremely close to us.About one. Our galaxy is surrounded by several dwarf galaxies, that are extremely close to us.About one.

Why is it important to view galaxies that are far away and galaxies that are close?
To know what is the life there, and if there's any other creatures or "aliens". some scientists are looking for planets with water and life on them.
Explain how all galaxies are similar?
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.

Are Irregular galaxies are very large.?
Yes, they are usually of a similar size range to other types of galaxies, from a few thousand lightyears across to a million or more. Their formation is often as a result of two or more galaxies colliding, or coming close to each other.
How does a galaxy differ from the constellation?
The constellations are apparent from Earth as groups of a few stars (they may be at very different distances from ech other in space but from right here they appear relatively close together. Galaxies are billions of stars held together by gravity. There are only a few galaxies that can be seen with out a telescope and the brightest is M31 (or NGC 224) Andromeda (apparently inside the constellation called Andromeda but at a distance of bout 2.5 million light years).
Will an electron feel a greater force when it is close to the nucleus or when it is further away?
further away :)
