What's the name of the galactic supercluser we're in?  How many galaxies are in it?  Is there a map or diagram somewhere that shows where the Milky Way is relative to the other galaxies in it?  How big is our galactic supercluster compared to the distance to the next supercluster?  What's the name of the nearest galactic supercluster besides our own?  Please provide a link to any information or pictures.

The Virgo Supercluster.\nWikipedia knows all.

The space between the galaxies is what is expanding.  Imagine raisin bread being baked.  As the bread rises, each raisin moves away from every other raisin.  Another way to visualize this is by drawing dots on a balloon then blowing the balloon up.  As the balloon get's bigger, each dot moves further away from every other dot.  It's the same for galaxies.\n\nNow the expansion of the universe is only detectable at extremely large distances.  Nearby galaxies like M31 can move towards us.  But most galaxies we see are extremely far away, so almost all of them are receding from us.

The Universe is expanding, but individual galaxies are not expanding.  So the stars within a galaxy aren't getting farther apart from each other.  Similarly, our solar system is not expanding (many people get confused about all that).\n\nIn fact, even galaxies within a cluster of galaxies aren't moving apart from each other - for example, the Milky Way galaxy and the Andromeda galaxy are moving *towards* each other, and will collide in a few billion years.  It's the clusters of galaxies that are moving away from each other.\n\nEven though the galaxy itself isn't expanding, the stars are all moving relative to each other.  They all rotate the center of the galaxy, and they also have random motions.  So (as other people above have said) the constellations as we see them today will change - their shapes will become more and more distorted over time.  Here's a neat website which shows what the Big Dipper will look like in the future: http://www.fourmilab.ch/yoursky/help/proper.html

Well I found this really cool map a while back. It's not from a reliable Star Wars source (i.e. www.starwars.com or www.theforce.net) but it looks pretty good. Check it out.\n\nThe second one is almost exactly (if no exactly) the same. \n\nI don't know if this is what you wanted, but it's something.

universe = infinite ... and if not infinite it's still pretty freakin big... how can we be so sure that somewhere out there there isn't a solar system similar to ours and a planet similar to ours?  A planet with gravity, oxygen and water just like ours?  A planet with life just like ours? …. Uh… oh… A planet with life more advanced than ours?  Or even less advanced than ours?  Was I supposed to give an answer?  Oops!

Actually you can look at all the other stars in our galaxy and via rather simple mathematics make a point of view outside the galaxy. So, more or less, making a simple computer program for it and feeding it all the coordinates that we have on the other stars, then adding our own star as 0,0,0 and voila - a picture of the galaxy and an arrow pointing at us.

About 100000 light years diameter.   We're about 30000 light years from the centre.   The centre of the disc part of the galaxy is about 3000 light years thick, and it gets thinner towards the edge.   But there's a spherical halo containing a few stars surrounding the disc structure.

Might be better to be more specific and tell us the question.  It is hard to just give you information on space - seeing as it is infinite for starters.

http://www.astronomycafe.net/cosm/dimens.html\n\nlong, but good explanation\n\nalso, do a search for a hypercube...you should find some interesting info there.\n\nhttp://rds.yahoo.com/_ylt=A0Je5mF.7vJDtigAKCNXNyoA;_ylu=X3oDMTE2bzk5aTlkBGNvbG8DdwRsA1dTMQRwb3MDMwRzZWMDc3IEdnRpZANGNTYxXzg4/SIG=12aalomvk/EXP=1140080638/**http%3a//www.physicsforums.com/printthread.php%3ft=16762\n\nsort of a debate on the topic, a lot of idiots speaking their mind too.  \n\n\nFor questions like this, all you have to do is a yahoo search... I wish people would stop being so lazy

i don't think in terms of the universe being massive compared to the size of galaxies,but minuscule compared to that which is outside the universe, that way there is an endless supply of material on hand.here at the"center of the universe"it's all relative to our thinking everything is so large but since all we can do is theorize about whats out there,why cant we theorize outside the box,way outside the box. where did science get this idea ? i believe that a chaotic set of galaxies brings about an ordered universe that is a single organism of a larger set of chaotic universes,which in turn forms ordered groups of galactic multiverses which is a small component of a megaverse ,and so on

There was a supernova discovered recently in the galaxy M100. It is being labeled Supernova 2006X.\n\nThis is a discovery picture, I think the line is supposed to point to the Supernova:\nhttp://www.rochesterastronomy.org/sn2006/n4321s1.jpg

Some distant galaxies appear to be accelerating away from us, not just moving at a uniform speed. \n\nAnd the most distant galaxies are probably expanding away from us at more than the speed of light. This does not violate the special theory since no information is being transferred (see reference).

One theory is that every galaxy has a super-massive black hole at its center, which is slowly drawing all its stars into it. Plus the galaxies are being drawn into each other. If this continues, all matter will ultimately be drawn into one enormous black hole, which will collapse into itself and then...BANG! It starts all over again. Of course, there will be no humans around to witness it. Our star would have been destroyed long before that...

we have a hubble telescope. its actually a giant satellite that orbits in space. takes pictures. and sends them to computers on earth! neato!\n\nbut an intersting thing is, the pictures we get of other galaxies are what they looked like millions of years ago! thats because it takes millions of years for light to travel from THAT galaxy to THIS galaxy. :)

Unfortunately we do not have any concrete evidence.  Here is a good quote by the late Carl Sagan:\n\n"There are some hundred billion (1011) galaxies, each with, on the average, a hundred billion stars. In all the galaxies, there are perhaps as many planets as stars, 1011 x 1011 = 1022, ten billion trillion. In the face of such overpowering numbers, what is the likelihood that only one ordinary star, the Sun, is accompanied by an inhabited planet? Why should we, tucked away in some forgotten corner of the Cosmos, be so fortunate? To me, it seems far more likely that the universe is \nbrimming over with life. But we humans do not yet know. We are just beginning our explorations. The only planet we are sure is inhabited is a tiny speck of rock and metal, shining feebly by reflected sunlight, and at this distance utterly lost."

Most of the stars we see with the naked eye are within our galaxy.  If you lived in the southern hemisphere, you could see the Mangellanic clouds, which are two small satellite galaxies of the Milky Way.  You would not be able to see induvidual stars, but you would see the glow of millions of stars within them.\nIn the northern hemishere, if you are in a very dark place, you can see the Andromeda Galaxy, which is 2.5 million light years away but you can see the glow of the billions of stars that make up that galaxy.\nBut all the induvidual stars we see in the night sky with the naked eye, they are within our Milky Way galaxy.\n\nAnd for stars between galaxies...yes there are.  There are a few stars that get cast off and tossed into intergalactic space.  There is one right now that has been flung out of our galaxy at a bit over a million miles an hour when it had a close encounter with the black hole in the core of our galaxy.  There are millions, perhaps billions, of stars in the galactic halo around the Milky Way...they are just difficult to see, even in a big telescope, as they are mosly dim red dwarfs.  The space between galaxies is not empty...things are just spread out a bit more.
