Everything is made of matter, and all matter is made of atoms. Atoms are made of protons, neutrons, and electrons which are all made of quarks and bozons. It gets smaller but those are as of yet unknown.

What is made up of billions of stars held together by gravitational attraction?
The star groups are galaxies, or possibly globular star clusters.
What are billions of stars held together by gravitational attraction?
They form galaxies, galactic clusters, and galactic superclusters.
A group of stars gas and dust held together by gravity is a?
A group of stars, dust and gases held together by gravity IS CALLED GALAXY
What parts hold the galaxies togher?
Galaxies are held together by the gravity, which results of their mass. It turns out that the mass of the known stars and other objects is not enough to hold galaxies together (they rotate way too fast for the known masses) - rather, much of the mass - about 80%, though it depends on the individual galaxy - is made up of an unknown substance, currently called "dark matter".
What made bones held together?
Bones are held together by ligaments.
Is there gravity in outer space?
Yes, gravity exists in outer space. Gravity holds the moon in its orbit around the earth. It holds the earth in orbit around the sun. It holds the milky way galaxy together. It holds the local group of galaxies together. And the local group of galaxies might be a group of a string of galaxies held together by the great attractor.
What is gravitys role in the structures of galaxies?
It's what holds them together. (what's it like in your universe? ... since you're implying that yours is different.)
What holds the galaxies and solar systems together?
Galaxies are held together by gravity. So are Solar Systems. In the case of galaxies, and galaxy clusters, it isn't entirely clear what type of masses provide this gravity - the amount of known matter is simply too small, by a factor of 5-10. For more information, do some reading on "dark matter".
Do galaxies hold everything in space?
No. Space holds everything in space. Galaxies are held in space by space.
What are galaxies mainly made of?
Galaxies are made up of billions to trillions of stars.
What kind of star is Berenice's lock?
Berenice's Lock, also known as Coma Cluster of Galaxies, is a galaxy cluster. It is a group of galaxies held together by gravity, rather than being a single star. It is named after the constellation Coma Berenices where it is located.
When a number of cluster of galaxies join together they form a of galaxies?
That's called a supercluster.
