Galaxies
Galaxies are large systems of stars and interstellar matter, and they contain billions of stars. Our own galaxy, the Milky Way, has 200 to 400 billion stars, and there are over one billion known galaxies. Questions that have to do with galaxies in general and specific galaxies are perfect for this category!

Is the center of the universe more crowded with galaxies than any other place in the universe?
yes and no, according to the big bang theory, all things began in the middle,creating the possibility of more galaxies in the center. but according to the universal light theory, all things in the universe are evenly sorted out. The understanding of this concept relates to timetravel, than a harder explanation using math and many previous theories to solve
Does the Milky Way contain the local group?
No. The local group contains the Milky Way and a few other galaxies.
What type of galaxy is bright in the center?
I guess that would apply to any galaxy, since stars will have a tendency of accumulating towards the center.
Why are spiral galaxies mainly blue or white?
If a galaxy shows any significant colour band, then it is due to the type of stars present in that galaxy. A blue or white galaxy would have to have a predominant amount of OB stars to project that colour band.
Spiral galaxies do not have significantly greater amounts of OB stars, so it is only a "visual" appearance, not a factual one.
What do all active galaxies have in common?
In theory, all galaxies originate from the Big Bang, which is the name that describes the explosion that propelled all matter into the cosmos. All galaxies are moving. All galaxies produce energy like light and gravity. Think of galaxies like you would human beings. Although very different in some ways, they are mostly the same.
What is the most accurate way to determine the distance to a very distant irregular galaxy?
Cepheid variables
What is a galaxy that is shaped like lens and has no arms?
Elliptical galaxies, Lenticular galaxies and Irregular galaxies.
What galaxy has an oblong shapeand is no longer producing new stars?
There are elliptical, spirals, and irregulars. non of them are circular persay.
Is a galaxy bigger than a moon?
Yes, much bigger. There are many stars in our galaxy, thousands of millions of them. Everything you see in the night sky is in our galaxy, including the Moon, so the galaxy is much bigger.
What galaxies have a variety of shapes and sizes and are less common than other types?
there are as many galaxies as their is grains of sand all over earth and mars so it really does not matter but the answer:spiral but the least common is oval
What is a Large Magellanic Cloud galaxy?
The Large Magellanic Cloud is the larger of two irregular galaxies that orbit our own galaxy.
Can 2 spiral galaxies create a elliptical galaxy?
yes they can and if that happens the galaxy will be destroyes :)
Where is are sun located in the milky way galaxy?
The Milky Way Galaxy is located within the Local Group of the Virgo Supercluster.
See related link for a pictorial of our location (Red arrow)
Is this true an elliptical galaxy has mostly old stars?
Both - all galaxies contain young and old stars.
What is milky way best described as?
It is the SOLAR SYSTEM where the Earth is part of it( A Solar System Consists of Planets, Moon, Stars like SUN, Asteroids, Meteors, Comets and sometimes Black Hole).Above the surface of the Milky Way, Millions and Billions of Cluster of Stars are Scattered around it. A Cluster of Stars are made up of Looking-Young Stars but, They are actually old since the Milky Way was formed around 12 Billion Yrs. old.
How many constellation are near the milky way galaxy?
All of them. Any star you can see with the naked eye is within the Milky Way Galaxy.
How much time would it take to travel to the nearest galaxy with present resources?
Travelling at the speed of light, It would take about 2.5 million years. Travelling at conventional rocket speeds, it would take billions of years.
Why does our galaxy the milky way look hazy when viewed on a clear dark night?
What you are looking at is just one spiral arm of the galaxy. The stars in it are so distant that they cannot be seen individually. Rather, their light melds together into a seemingly continuous haze.
What are the galaxies in the whirlpool galaxy?
There is not much solid information known about planets in other galaxies. Most planets discovered so far are in our own galaxy. This is because it is easier to discover a relatively near-by planet than one that is much farther away. However, the planets found so far make it likely that in our own Milky Way, and therefore other galaxies as well, have at least as many planets as stars.
What are the 3 different types of 'shape' classifications for galaxies?
There are usually 4 classifications:
Elliptical, spiral, (including barred spiral), lenticular, and irregular.
(However some classifications do have only 3 types.)
Is a spiral galaxy symmetrical?
Considering the fact that a spiral galaxy is indeed a spiral, I will say no.
