That is still a mystery. Obviously, they are held together by gravitation. Each star attracts each other star, and you might say that the combined force of these attractions keeps the galaxy together. But the known matter in our galaxy - and in other galaxies - isn't strong enough to account for the fast rotation a galaxy has. There must be about 5-10 times more matter, compared with known matter, in something invisible - commonly known as "dark matter". This mysterious dark matter can be noticed through its gravitational attraction, but it can't be seen directly.
A star is held together by two main forces: gravity, which pulls matter inward, and radiation pressure, which pushes matter outward. Gravity tries to collapse the star, while radiation pressure from nuclear fusion in its core creates an outward force that balances gravity, maintaining the star's equilibrium.
The stars are not "held" fixed in the sky, but are so far away that their movement is imperceptible. The whole of the universe is a moving, expanding, seemingly infinite array of stars, galaxies, and huge groups of galaxies, in a cosmic expanse of which Earth is only a tiny part. (But, as far as we know to date, we are the only consciousnesses here to witness it.)
Stars are held together by gravity.
A star is basically a body that produces energy at the same rate as it contains it.
The mass of a star holds it together. The gravity of the mass atomically draws it toward the middle of the star.
Yes. Actually, the gases in the stars are considered to be in a "fourth state of matter", called plasma. The difference is that in a plasma, many of the atoms are ionized.

What fundamental forces pulled together hot dense areas of matter in the early Universe to begin the process of star formation?
gravity
What is a nuetron star made of?
A neutron star is made predominantly of neutrons, as its name suggests. These neutrons are densely packed together due to the intense gravitational forces present, creating a compact stellar remnant with a very high density. In addition to neutrons, a neutron star also contains protons, electrons, and other subatomic particles.
What would happen to the Sun if gravity exceeded pressure at some point?
The sun would collapse and increase in density. This would increase the rate of nuclear fusion which would try to hold the star apart even harder. At some point other forces like the electron degeneracy pressure would come into play to hold the star apart. If all those forces failed though the sun would become a black hole.
Which type of forces are present in stars that they are stationary still they are not falling?
Stars are held in equilibrium by a balance of two main forces: gravity, which tries to pull the star inward, and radiation pressure, which pushes outward due to the energy generated in the star's core through nuclear fusion. These forces counteract each other to keep the star stable and prevent it from collapsing under its own gravity.
What forces are opposing one another throughout the life of a star how do they influence the various stages in life cycle of a star?
In the life cycle of a star, the force of gravity tries to collapse the star inward, while the force of nuclear fusion pushes outward to provide energy and heat to counteract gravity. These opposing forces determine the balance between contraction and expansion that defines the different stages in a star's life cycle, such as main sequence, red giant, and supernova.
What force make a star?
All of the forces act to make a star. Gravity is the main force, which pulls everything together, and the other forces ignite the star.
What are the main forces that make up a star?
Objects are not made of forces. A star is made of hydrogen, helium and, later in its life, heavier elements.
What was the star of david made out of?
two trangles put together
What are stars in the sky held together by?
Stars in the sky are held together by gravity. Gravity is the force that pulls all the mass of a star together, preventing it from expanding outward. It is this balance of internal pressure from nuclear reactions and gravitational forces that keeps a star stable.

Something sweet to say when you want to get back together with your boyfriend?
I've always thought you.... or If I could hold a star for every time you made me smile, I would have the whole night sky in my hands. Sorry if this didn't help
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 the release dates for Star and the Forces of Evil - 2014?
Star and the Forces of Evil - 2014 was released on: USA: 2014
What force forms a star?
The mass forces the star to form
Why is there star on barn?
The star on the side of a barn is a hexmark. It is meant to ward off evil magic and witches/warlocks who work with evil forces. There are those who hold a strong belief in the matters and symbols. Whether of not you believe, there are those who do.
