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!
No, it is not a 'real' galaxy, merely one that exists inside the movie world. It is based upon Science Fiction, and you will not be able to travel to it.
Earths atmosphere consists of 78.09% Nitrogen, 28.95% Oxygen and 1%  trace elements, mainly Argon. The martian atmosphere consists of  96% Carbon Dioxide, 1.9% Nitrogen, 1.9% Argon, with oxygen present  only as a trace element. Where you to inhale the martian atmosphere  you would suffocate. The...
Scientists measured it in light years. The Milky Way takes 100000  years to get from one side to the other at the speed of light.
The decrease is caused because it makes the spiral galaxy move  further apart.
In the Northern Hemisphere from June through February
Galaxies occur solar systems that formed after the universe exploded.
yep, Earth: Milky way galaxy, saggitarius arm, sol, third orbit. :D all you need to do is ask a nerd :P
The galaxy was named after milk because when early astronomers looked at the sky they noticed a band of stars that somewhat looked like milk!
That will depend on the speed. At the speed of light, it should  take about 26,000 years, since the center of the Milky Way is about  26,000 light-years away from us.
Andromeda is the wife of Perseus and the only mother of his  children  seven sons: Perses, Alcaeus, Heleus, Mestor,  Sthenelus, Electryon, and Cynurus as well as two daughters,  Autochthe and Gorgophone. 
Andromeda was a mortal princess of Eithiopia and later wife of  Perseus and queen of Mycenae.
No, the Koopa Kids don't appear in Galaxy 2.
the answer to this question from the nasa website is 26,000 light years.
About 2.5 million light years from Earth, but since the Earth and  Sun are only 8 light minutes apart, there isn't that much of a  difference in how far the Andromeda Galaxy is from the Sun or  Earth. So the Andromeda Galaxy is about 2.5 million light years  from the Sun and Earth.
Nebulae or star clusters within the Milky Way Galaxy.
Well, there is a way to be specific, but Astronomers estimate that  the Milky Way contains up to 400 billion stars of  various sizes and brightness. Meaning, there are A LOT.
An irregular galaxy is a galaxy that does not have a regular shape, like a spiral or an elliptical galaxy.[1] The shape of an irregular galaxy is uncommon - they do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge...
Messier 87 is an elliptical galaxy.
A Glaxy is Samsung's electronic tablet answer to Apple's iPad.
Gravity is a field or a force, and, hence, has little to do with  speed.
I would say about 500 million light years
Estimates have tended to range between 300 billion to 400 billion.
Thousands of years ago, people saw the galaxy from Earth, and they  thought it looked like a spilled carton of milk.
No. The world we live on is a planet. That planet orbits the sun,  which is one of many stars in a spiral galaxy.
personally i have discovered about 21 but im still workin on findin more
Only tides on Earth are called "high" and "low." But these occur when the tidal force is the strongest and the weakest, respectively. So the strongest possible tidal forces exist around black holes whose Event Horizon is very small.
You can find them on most nights depending on the weather and what  hemisphere you're in.
I have no FREAKING idea this site it a waste of your time so dont ever use it agin or i will hunt u down wall ub sleep you hear me never use this site agin!have a nice day :D:D:D:D:D:D:D:D
We are part of the milky way galaxy, so we are moving with it.
Yes. A galaxy contains many stars.
The very center is believed to contain a very powerful black hole.
If you are talking about my mind probably 150,000 Lightyears across but if your talking about space probably 100,000 light years in this galazy
There are thought to be between 200 billion and 400 billion stars in our galaxy. So for every star, there could be several planets in orbit. This is just our galaxy though, there are then thought to be 100 billion galaxies or more, so total number of stars in the universe is massive.
Elliptical galaxies, Spiral galaxies, and  Irregular galaxies.  
Well. The solar system from Mercury to Pluto is 32 years across. The solar system is full of stars and planets and it has the sun that also is a star that will burn into a red giant in just 4.5 billion years! and gobble up Mercury, venus and earth. The milky way is full of stars and is the main...
The galaxy clusters are the solar systems orbiting the galaxies.
220-240 million years.... Imagine how insignificant we really are. The last time our solar system was at the point were at now, dinosaurs just started roaming the earth. Our solar system orbits at 600,000 miles per hour
Yes, there are huge clouds of hydrogen gas, called nebulae.
The Milky Way Galaxy is classed as a spiral galaxy as it's appearance is of a spiral with looser outer stars becoming denser the closer you get to the centre. As a picture is worth a thousand of my words, the the related link for a generated picture of our galaxy. Note: This is a computer...
The Milky way, Our Sun is near the galactic core in the Orion arm,  lets say ah, about 27,000 light years away.
100,000 Light Years = 6.32396717 x10^9(ninth power) au
There are some red dwarf stars(dwarf ellipticals) in the Milky Way that seem to date back to about 1 billion years after the Big Bang.
That really depends on the exact interpretation of the term "discovered". We haven't actually sent probes (manned or unmanned), even to the nearest star - whose distance, about 4 light-years, is a trifle compared to the size of the galaxy (about 100,000 light-years in diameter). We do have a general...
The Milky Way Galaxy is about 100,000 Light Years across. Each light year is about 63,241 Astronomical Units. An Astronomical unit is the average distance between the Sun and the Earth, or about 93 million miles. Based on that math we form an equation. 100,000x63,241=6,324,100,000 Astronomical units...
No. The Milky Way is the galaxy of which our solar system is a tiny  part.
About twice the size of the Milky Way, so about 200,000 light-years  across, so the Milky Way is 100,000 light-years across.
Well it depends what u mean because maybe its because you observed it in a large picture or u viewed it from above
I heard the ancient Greeks called our galaxy the Milky Way because they thought it was made from drops of milk from the breasts of the Greek goddess Hera...
The nearest and the largest galaxy to the Milkyway is the "Andromeda Galaxy."
The Andromeda galaxy is about 2.5 million light years away from the  earth.
The little dipper (Ursa Minor) consetllation along with a few otherconstellations are always visible all year round in the northernhemisphere, it's just a matter of wheather and air pollution thatmay make it difficult to find in the night sky. To find it, you caneither use a compass to find the...
Because it's a part of a very important constellation. It can be found in the winter/spring sky.
no the galaxy is way to big for a black hole to do much in fact we  now know that there is a supermassive black hole in the center of  our galaxy right now.
There are about 400 billion stars in galaxies
Big Bang is a model of the universe which specially deals with the  question that how the universe might have started.It mainly  suggests that 13.798 billion years ago,all the matter in the  universe was concentrated into a point of zero size,with infinite  density,mass and spacetime curvature...
the milky way is the galaxy in which we stand. it has constellations in it but is not in a constellation
Alrisha is a binary star (two stars) that are both white dwarfs. It is located at the bottom of Pisces, and is the star that binds the tails of the two Pisces fish together. Since both stars are white dwarfs, the stars are degenerate, meaning they no longer fuse energy, and are in the process of...
100,00 light years across
mostley lower-main stars and gases and dwarfs
Sol drags its' planets and all the rest of its' debris through the Milkyway galaxy.
the solar system is a tiny speck comparing to the milky way ;0
The Andromeda Nebula, now known as the Andromeda Galaxy, has no  discoverer as it is visible to the naked eye. The idea that it was  a galaxy and not a nebular was fist proposed in 1917 by Heber  Curtis and proven in 1925 by Edwin Hubble.
The milky way "composes" an infinitesimally small part of the universe. Should this question actually mean "What is the milky way composed of?", here is an answer: The Milky Way is a galaxy and is therefore composed of many different celestial objects, including: stars, planets, comets, asteroids,...
The Milky Way is the Galaxy our solar system is located in along with many other solar systems. In turn many Galaxies go to make up the Universe. It will take time to get your head around this concept If your curiosity has only just awoken.
It is vital that the solar system is in a quiet part of the Milky Way because our odds of having collisions with other stars is extremely low...unlike the center of our galaxy.
That's in the constellation Sagittarius. That's in the constellation Sagittarius. That's in the constellation Sagittarius. That's in the constellation Sagittarius.
Andromeda, our closest galactic neighbor, is about 2 million light years away. Still, you can see her without a telescope if you know where to look.
Sounds cannot be heard in space to begin with, so hearing any from anny time is impossible.Secondly, the energy in a mechanical wave such as sound is dispersed and transformed as the wave travels. After a while all of this energy is turned to heat, and the wave ceases to exist, so even if sound...
At an apparent magnitude of 3.4, the Andromeda  Galaxy is one of the brightest Messier objects, making it visible  to the naked eye on moonless nights even when viewed from areas  with moderate light pollution. 
Galaxies are mostly empty space. Even in our neighorhood in the middle of an arm of the Milky Way galaxy, there are no more than 20 stars within 10 light years from the Sun. That is very sparse.Imagine shooting two shotgun blasts at the same point from two locations 200 meters apart, do you think...
Because we see the Milky Way All around us.
A galaxy is a vast, gravitationally bound collection of billions of  stars and their associated "friends."    Their "friends" include nebulae, stellar remnants, planets and a  whole host of other smaller particles including the basic elements  hydrogen and helium. Galaxies also consist of an...
it is predicted that Andromeda and the Milky Way will collide within the next 5 billion years.
Proof of life in other galaxies! Sorry, I just had to do that since (if I am not actually answering an exterrestrial's question) it is your galaxy too. Anyway, I don't know why the Milky Way looks milky. I am guessing it has to do with the way the light shines on it. However, there is no scientific...

The distance between the stars that form the constellation.
No, it is a spiral galaxy.
The name of our home galaxy is the Milky Way. This was the name given to the dense band of stars across the night sky, which mark the plane of the galaxy when looking toward the center of its disc.
wrong its billions and trillions
Our Milky Way galaxy is a ' Barred Spiral ', type SBc . Edwin Hubble classified these types of spiral galaxies as "SB" ("Spiral", "Barred") in his Hubble sequence, and arranged them into three sub-categories based on how open the arms of the spiral are. SBa types feature tightly bound arms. ...

It was where I was born
Scientists still are not sure why most galaxies contain  supermassive black holes. One idea is that the first stars, which  were very massive, formed smaller black holes when they died which  then merged together. Another idea is that large clouds of gas at  the centers of the proto-galaxies...
