Are their people in other galaxies?

people?\ni don't think so ... people means you and i and a few billion others living on earth. by definition, anyone else would be called an alien.

We do not know that they are still there.  When astronomers look at galaxies billions of light years away they are looking billions of years back in time. To put it another way this ancient light really left that galaxy billions of years ago.

Almost certainly, but probably not in our solar system.  There are billions of galaxies out there, each containing billions of stars - you work out the odds

Yes, there are clusters of galaxies. As was stated, the one with the Milky Way galaxy is called the local cluster. Other clusters close by are the Virgo cluster and the Coma cluster; named for the constellation where you can see these galaxies. As you go to larger scales, there are also superclusters of galaxies.

They really don't. Galaxies come in all sorts of shapes and sizes, spiral, elliptical, round, etc. Few are rotating though, and some in different directions. All seem to be moving away from each other, though, as most scientists agree that the Universe is still expanding,thus blowing a few holes in the old "big bang" theories.

No.\n\nGalaxies are groups of stars and planetary systems.\n\nA single sun (even ours) is not powerful enough to have a galaxy rotate around it (gravitationally speaking).\n\nDoesn't work that way.  We move around inside the galaxy, not the galaxy around us.

The expansion of the universe is the main reason. Yes, there are certainly stars in every direction, most of them contained within other galaxies. At extreme ranges (about 13.7-billion light years) those galaxies are moving away from us so fast that their light is effectively red-shifted out of sight.

They don't exist.\n\nThey exist and have a level of technology similar or less advanced then we have.\n\nThey exist and have a superior level of technology.\n\nIf they have our level or a lesser level of technology it is not likely that we would know about them. With our current ability to communicate long distances it would take thousands of years to get a signal from the nearest galaxy, or to travel those distances. \n\n\nIf the have a superior level of technology we would probably not be able to detect them. \n\nSo, it is possible given the size and scope of the universe, however, it would be damn hard to prove.

We are one of many planets surrounding a star at the edge of a Galaxy which contains billions of other stars.  There are many other galaxies in the universe with about the same amount of stars and planets.  I think that we would be naive to think life does not exist anywhere else.  I don't know if we will ever be able to travel the distances required to find out.  Technology will have to develop a considerable amount for that.  But, considering what we have accomplished in the last 100 years, we may do it.  Maybe not in my lifetime, but in yours or your children's.

the universe is enormous, there are thousands of galaxies, i'm pretty sure we're not alone

They are not from this earth.  They are just visitors and that's their way of communicating with others of their type.

It's the name of the galaxy we are in. :)

i do because there are many galaxies are there. but you just wait because in the next 20 years we'll  be able to detect alien life forms other than our planet because if there are those aliens are trying to contact with us by waves (like we use on our planets for example, radio waves.) there is evidence that life used to exist on mars. not like life like us (like mircoscopic things). there are many stories that aliens have come to visit our planet. can be true because as they are as they are described in the movies all these phonomenons are happening buts its not possible for us yet to go visit another galaxy. not eveough human years. but in the next upcoming years we'l have ships that will be able to jump into time. as we are doing right now for example, when a space shuttle stays in orbit for atleast a year, they jump into time by 3.8 seconds. its hard to believe but its true . in star trek when they jump into time there using those worm holes. they exist but there so damn small that we have to enlarge them. there smaller than an atom. as phsyics desribres its not possible to go as fast as the speed of light it'll be possible in the next upcoming years. (i dont no when though) but if we go any faaster than the speed of light we'll be crushed by the gravity so that is why we'll be using worm holes and that is one way that we'll be able to visit other galaxies. i hope i stay alive doing that time lol

Do you mean SPIRAL galaxies?\n\nCompare the Milky Way (our "spiral" galaxy) with others in the universe. There's a classification for spirals, so it shouldn't be that hard to write a paper on it (without be a physicist)

If by human-like you mean intelligent, then yeah, it's almost certain that there either has been, is, or will be other, or many other intelligent life in this universe. \n\nThe saddest part of living in this massive universe is that another intelligent civilisation could have existed, learned to travel at the speed of light, visited thousands of star systems, and then became extinct, all before the first dinosaur even existed. And there's a decent chance that after all that exploring they may never have found any evidence of another intelligent species.

If you are referring to other planets that are habitable, I believe that mathematically there has to be intelligent life in other parts of the universe. Here is why.\n\n1. The Hubble Telescope estimates that there are 125 billion galaxies.\n2. Each galaxy has roughly 100 billon stars.\n3. If even 1% of those have planets and only 1% of those are habitable and only 1% of those have life, the odds are high.\n\nThe odds are extremely favorable for there to be extraterrestrial life. \n\nOne can use Drake's equation to calculate the chance of life in our galaxy. Multiply that result times the number of galaxies. See the second link below.\n\nA totally different question would be whether or not we would actually interact with extraterrestrials...\n\nI will leave that one to another Y! Answers Question

Come to think of it... we all know that our planet is an insignificant speck circling an ordinary star, far out on a spiral arm of the Milky Way Galaxy, which is an ordinary congress of a few HUNDRED BILLION stars among at least a HUNDRED BILLION GALAXIES!!!\nWe are still the only intilligent life we know of anywhere. But now humankind has taken a dramatic leap towards a possible demotion. Planet-hunting scientists and astronomers world wide are refining their technique in detecting other planets in far off stars & galaxies. who knows that one day, we may be able to find a world that is much like ours?\nFor now, humanity can bask in its special status as the only life known to be contemplating such questions. Many scientists predicts that this distinction, too, will crumble. But the search for other worlds is not only a quest for kindred intelligenc. it is also about the destiny of human species. Where are we going to be a hundred million years from now? Where will we go, and how will we get there? And how will it change who we are? _end
