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!

In rogue galaxy how do you get dorgenbreaker?
The best possible way of getting info head to neoseeker and type in rogue galaxy. It will give you lots of cheats and how to get every possible item by finding or mixing it with toad
What is the relationship between planets stars and galaxies?
Planets generally orbit around stars. (Some interesting speculations suggest that there may be "free planets" that are not near any star.) Billions of these solar systems orbiting their common center of gravity form a galaxy.
How do you know your galaxy is a flat disk?
We don't for sure as our vantage point does not allow us to determine that. However, by viewing other spiral galaxies (Andromeda, Sombrero galaxies) we can make a calculated guess that our galaxy is shaped in the same way.
Also, while we can't see the galaxy as a whole, what we can see is consistent with it being a flat disk... specifically, we can even tell that it appears to be a barred spiral galaxy.
Are there considered the building blocks of the universe. and why?
The universe building blocks are chemical elements. (I use Switched on Schoolhouse and this is the answer.) hope this helps :)
In the Greek geocentric model the retrograde motion of a planet occurs when?
The planet is travelling in an epicycle, therefore on it's orbit around the earth it looks like it is travelling backwards, because the epicycle rotates faster than it orbits earth.

good source.
The constellation that contains the pointer stars used to locate Polaris the North Star?
Ursa Major/The Great Bear/The Plough/The Big Dipper/The Drinking Gourd.
What is believed to be the solar mass of the black hole candidate at the center of the galaxy M87?
At the core of M87 is a supermassive black hole with about 6.4×109 times the mass of the Sun (See related question)
When was Spiral Walls Containing Autumns of Light created?
Spiral Walls Containing Autumns of Light was created on -19-05-04.
Are all galaxies the same size?
All galaxies are different sizes and mainly four different shapes,spiral,barred spiral,elliptical and irregular
Are some galaxies very small and have only a few thousand stars?
These small galaxies are believed to be the result of collisions between larger spiral galaxies. During such collisions pieces of the spiral arms get flung out into space, becoming small irregular galaxies.
Why do the stars of the galaxy appear to form a bright band that extends around the sky?
The Sun is one of a billion stars in the Milky Way Galaxy. It is a little less than a quarter of the way out from the centre of the galaxy. Think of yourself standing a quarter of the way out from the centre of a huge crowd. If you look towards the centre, you will see a huge number of people but even looking in the opposite direction there will be lots. So whichever direction you look in, there will be loads of people. It is only if you look up or down - across the plane of the crowd - will the numbers thin out. I hope this analogy works for you.
Why can you see Ursa Major all year?
Most constellations are visible about 300 days per year. Only when the Sun is very close to that constellation is it entirely hidden. But since few of us get up before dawn to study the sky, we typically see only "evening" stars.
Some constellations, such as Cassiopeia and Ursa Major are "circumpolar"; they are close enough to the celestial pole that they are, depending on your latitude, always visible.
In order to provide a better answer, I would need to know your latitude.
47 degrees latitude
Will you ever go to other galaxies?
People have never been known to have ever visited other galaxies. With recent technological advantages, going to another galaxy may be possible in the future. As people have never manned a space trip to any space body besides the moon, the probability of traveling to another galaxy remains low, though not impossible. Also, as time goes by some galaxies are moving closer to the Milky-way galaxy, so traveling to foreign galaxies may become a higher probability.
So... it is possible in the future. You never know... if people in those other galaxies exist, they may visit us first!
What observation of the light from galaxies shows that nearly all galaxies are moving away from us?
The Red Shift or Doppler effect
About 60 percent of all known galaxies are classified as?
About 60% of galaxies are classified as elliptical planets.
Are there any other natural light source other than from the stars in the universe?
Yes. Matter falling into a black hole heats up can can produce tremendous amounts of light. Nebulae can also emit light from interactions with high-energy particles. Some minor light sources have been obseved in this very solar system, and even on Earth. Earth, Jupiter, and Saturn all produce glowing phenomena called aurorae and, along with Venus, also have lightning in their atmospheres. Earth is frequently home to fires that burn organix material, emitting light. Lava flows on the surface also emit light. In other solar systems, some planets, especially newly formed ones, are likely so hot that they glow.
What is a round or dislike galaxy called?
I have been learning the same thing you are. I hope I can help you. The answer is elliptical. An elliptical galaxy is the correct answer. Trust me I have learned this about a week ago. I hope I helped! :) Other galaxies can be the barred and the spiral. The milkyway is our galaxy and is a spiral. They call it a spiral because it looks like a tornado like it's spinning.
What does a galaxy contain the most?
Galaxies are made mostly of empty space. The most common elements however are hydrogen and helium.
