Empty Space?

Question

All of the stars,nebula,globular clusters that we see are contained in our Galaxy. And we see other Galaxys that have all the same. Are there stars and nebula between the galaxys

Answer 1

Sometimes, but it's not all that common. Stars can be ejected from galaxies from close encounters with massive objects (like a black hole) that gives them a gravitational push and a high velocity out of the galaxy. There is some gas out there too, but again, not a lot - pretty much all the mass in the universe is in galaxies, as far as we can tell (not counting the dark matter that apparently moves out of galaxies after some collisions).

Answer 2

There are very few if any. The presence of stars and nebulae between two galaxies is good evidence that the two collided in the past. Galaxies usually pass right through each other, because stars tend to be far apart. But the more massive galaxy would pull stars and debris out of the smaller one and leave a trail in its wake. The Large and Small Magellanic Clouds in the southern sky are diffuse collections of stars and nebulae that probably broke away from our galaxy sometime ago.

Answer 3

The first respondant to your question pretty much has the right idea. In general, the stars tend to be within galaxies. There are a few (relatively speaking) that are long distances from groupings (as in galaxies). Several theories have been proposed for the maintenance of these groupings, but none have been pushed into the forefront as being the correct idea as far as I know, yet.

Certain areas in outer space are simply filled with huge gas clouds and debris from exploding (colliding) galaxies and stars. Some of these dense clouds are the nursery for new stars which are being born from the new aggregation of these gases and debris. At Hublesite.org you can see several excellent pictures of these new stars forming in their gallery of photos. They are very impressive. Suggest that you have a look...

Answer 4

space is far from empty.
there is gas, dust, rocks, planets, stars, comets.
galaxies are like gigantic dustbusters. as they spin through the cosmos they pick this stuff up condense it and make stars and planets out of it. (otherwise they wouldn't grow)
with radio telescopes we know the space between galaxies has huge patches of dust/gas some even larger than our galaxy! (but obviuosly alot less dense) however if you look in the areas between the super filaments of galaxies and galaxy clusters into patches of 'open' space they are harder to detect if at all. space is full of dwarf galaxies and small and large globular clusters. and couplets and binaires. and dead long burnt out suns. even rogue black holes. this makes up all the baryonic matter. sad thing is the universe holds anywhere from 2-10% baryonic matter. the rest is stuff we can't detect but can see its gravitational influence (dark matter) and it makes up for the vast majority of the stuff in the universe and we don't have a clue what it is.

Answer 5

it's not certain for what is and not. Your questions can be clearly answered by the Caltech study resources...
