Nearby galaxies won't show much of a redshift, because they aren't moving away very quickly - or at all. For example, the Andromeda Galaxy, M31, is actually getting closer - and will collide with the Milky Way in about 3 billion years.

What are peices of evidence for the big bang therory?
You may want to check the Wikipedia article on the Big Bang, or science videos on YouTube, for more details; but briefly, the evidence is as follows:* According to calculations based on General Relativity, the Universe can't remain static for long - it must needs expand or contract eventually. * Similarly, the Second Law of Thermodynamics doesn't allow a static Universe. Entropy increases; there are irreversible processes. * The redshift of distant galaxies. The only reasonable explanation of this redshift is that the galaxies are moving away from us. This is related to,but not exactly the same, as the Doppler effect. * The mix of elements and isotopes in the current stage of the Universe closely matches theoretical calculations based on the Big Bang. * The cosmic microwave background radiation closely matches that which is expected from the Big Bang model. It is a remnant of the time when the Universe cooled below about 3000 K.
Are nebulas in elliptical galaxies?
Because of their age, elliptical galaxies are believed to have older stars and less gas and dust in their insterstellar medium than other types of galaxies, and thus their nebulae are less common. However, nebulae are presumed to exist in almost all galaxies; and some recent observations hint that the central black holes of elliptical galaxies may tend to preserve interstellar gas by preventing it from cooling enough for star formation.
How many moons does the Milky Way Galaxy have?
There are lots of spiral galaxies, so you shouldn't speak about the spiral galaxy as if there were only one, and while there are lots of moons inside galaxies, you may be thinking of galaxies that have other galaxies which orbit them; our own galaxy, the Milky Way, has the Greater and Lesser Magellanic Clouds as satellite galaxies, which perhaps is what you had in mind. A satellite galaxy is not a moon, however.
What are four general shapes of galaxies?
Galaxies have different shapes because of what happens throughout their lives. Any galaxy, at one point or another, will encounter another or many galaxies. When encounters occur, gravity takes over. The larger of the two galaxies will consume the smaller one, this is called galactic cannibalism. The act of absorbing another galaxy will change the size of the galaxy it's shape and even the speed of its rotation. Our own galaxy, The Milky Way, is as large it is (100000-150000 Light years across.) because of galactic cannibalism. The Milky Way is as we speak consuming two other small galaxy. And in about 2 billion years, our nearest nieghbor, the Andromeda Galaxy, will collide with our galaxy. Both the Milky Way and Adromeda galaxy are spiral galaxies, but after they collide the resulting new galaxy will an elliptical galaxy, which looks like a bright white sphere.
What does a galaxy rotate around?
I believe the current understanding is that galaxies (that are not part of local groups of galaxies) don't orbit anything. There is no universal center, matter seems to be distributed more or less evenly no matter what part of the sky we observe, and the galaxies are moving away from one another according to the current established principles. Some galaxies are members of groups of galaxies, and perhaps some of these groups are slowly turning on an axis, a little bit like materials in an accretion disk.
What type of galaxies may have their gravity distorted by neighboring galaxies?
one kind is lenticular galaxies
What type of galaxy moves away from Earth?
That has nothing to do with the "type"; it is how far they are away from Earth. Due to the general expansion of the Universe, galaxies that are far way from us systematically move away from us - the farther away, the faster. It is only nearby galaxies which may happen to move towards us.
Why do they think there are hundreds of thousands of galaxies?
They (scientists) think there are hundreds of thousands of galaxies because the universe is limitless so there may be billions of galaxies!
How do we know the universe began in explosion?
The Big Bang is a type of beginning of the Universe. It wasn't exactly an explosion in the traditional sense, and it may or may not have been the actual beginning.We know about the Big Bang, among other things, because of the redshift of distant galaxies (the only reasonable explanation is that galaxies are moving away from us); because the element distribution in the Universe closely matches what is expected from a Big Bang; and because the cosmic microwave background radiation, likewise, closely matches the expectations.
How are galaxies influenced by their surroundings?
About the only thing that can surround galaxies is other galaxies. Since many galaxies appear to lie in approximate lines, one thing that influences galaxy formation may be "superstrings," but these have yet to be directly detected.
Do galaxies all have the same shape?
Galaxies may have any of four general shapes. Elliptical galaxies show little or no structure and vary in general shape from moderately flat and round or oval to spherical. Spiral galaxies have a small, bright central region, or nucleus, and arms that come out of the nucleus and wind around, trailing off like a giant pinwheel. In barred spiral galaxies, the arms extend sideways in a short straight line before turning off into the spiral shape. Both kinds of spiral systems are flat. Irregular galaxies are usually rather small and do not have a symmetrical shape.
Are distant galaxies moving away slower or faster than nearby galaxies?
Here is what i belive to be the correct awnser. If you belive in the big bang theory then you swould know the universe started from the middle and started expanding out so the closest galaxie is moving away with us but distant galaxies are also moving away from us now i dont know about how they move or what speed they move at or if theres a differnce it is possible considering some galaxies formed billions of years after our a slowley catching up with as so i belive it varies now i hope this answer your question people may edit this in future and make it easyer to understand.
Which galaxies have a great many short spiral segments branching from the spiral arms?
This may refer to the so-called "flocculent galaxies". Perhaps it's the "multiple arm galaxies", which are sometimes put in with the flocculent type.
How may galaxies are there in the universe?
There are several hundred billion galaxies in the KNOWN (or observable) Universe; the actual Universe, however, is believed to be much, much bigger.
What do scientists think is the reason that irregular galaxies may not have consistent shapes?
they think that....
What are the release dates for How the Universe Works - 2010 Galaxies 1-3?
How the Universe Works - 2010 Galaxies 1-3 was released on: USA: 10 May 2010
What is an galaxy?
Elliptical galaxies may vary in shape form but are spherical or flattened disk-shaped galaxies (large groups of stars). See related link for a pictorial.
