The only similarity we know of is that they all seem to interact with gravity. Aside from that, scientists do not know what dark matter is.

How are stars dust and gas related to dark matter?
Stars, gas, and dust are all categorized as visible matter, not "dark" matter, but, since dark matter does not interact electromagnetically, the behavior of ordinary matter is used to study dark matter through their gravitational effects. You might say that stars, gas, and dust are like the leaves blowing in an invisible wind; the force can be perceived by the effects on the leaves even if you can't see the wind directly.
What is a basic building block of galaxies?
I am not sure there is one. Galaxies contain stars, gas, dust, black holes and other dead stars, and - above all - dark matter. The dark matter typically makes up 80-90% of a galaxy's mass.
What shape is dark matter?
A lot of it is probably more or less spherical. You see, "dark Matter," as distinguished from "dark Energy," which is really mysterious, is mostly just ordinary matter, which we can't see because it isn't lighted, either by nearby stars or its own heat. There could be numberless dark worlds out there just cruising through space; alternatively, dark matter could be finer than dust. The only thing we can say for sure is that there's a lot of it.
What does dark matter in outer space consist of?
By definition dark matter isn't something you can see. In scientific terms you might say it possesses mass but doesn't interact electromagnetically, that is, it does not absorb or emit light. This makes it hard to study; however, its effects are visible in somewhat the same way that wind is invisible but dust and leaves blowing in it can be seen: studies in the behavior of galactic and galactic cluster rotation hint at its presence, as do observations of cosmic background radiation and gravitational lensing. Particle physicists continue to search for a particle which would be a good candidate to explain this type of matter; alternative theories for its effects not involving matter are being developed.
What are the types of matter new stars can form from?
New stars form from the interstellar gas and dust; mainly hydrogen and helium.

What holds stars together to form a galaxy?
Gravity - from the stars, dust, etc., but especially from "dark matter", a substance of yet unknown composition.
How much space is in matter?
There is at least 5 times as much dark matter than normal matter. "Normal" matter in this case includes all matter of known composition, including stars, interestellar gas and dust, and even black holes.There is at least 5 times as much dark matter than normal matter.

What do you find in a galaxy?
Stars and any associated solar systems, dust, some gases and (potentially) dark matter.
What could be the possible exists between galaxies?
Dust, gas, dark matter, perhaps individual stars and planets.
What 2 components are spiral galaxies made out of?
Stars, dust, gas, black holes, dark matter...By far the most significant component, in terms of mass, is dark matter, making up about 80-90% of a galaxy's mass.
What compromises 99 percent of matter in the universe?
It is currently estimated that about 4% of the matter of the Universe is "normal" matter - matter that can be accounted for. This includes stars, dust, gas, and even black holes. About 23% of the matter is "dark matter", which makes itself manifest by its gravitational attraction - but that is about all we know about it. The remaining 73% is an even more mysterious "dark energy" - which somehow makes the Universe expand faster and faster.It is currently estimated that about 4% of the matter of the Universe is "normal" matter - matter that can be accounted for.

What does interstellar mean?
That means matter between stars - mainly dust and gas.
How are star dust gas and dark matter related?
There is no consensus on what dark matter or dark energy is so we cannot tell at this time.
What is in space beside planets and stars?
Galaxies, nebulae, black holes, dust, protostars, dark matter, and so much more we haven't discovered. Oh wait, I forgot neutron stars and super/hypernovas.

What is he solar system?
Other stars, with their own solar systems; lots of empty space; other galaxies; dark matter; dust and gas; black holes, etc., etc., etc.
