Where are the birthplaces of stars?
"Clouds" of gas (and dust) concentrated by gravity.
What are the different parts of the solar system?
A star, planets, satellites of the planets, asteroids, meteors, comets, dust particles and also vacuum.
Would dust fall due to no gravity on the moon?
Yes, dust would fall because the moon produces a gravitational field of its own.
What role does gravity play in supernovae?
Ok, a bunch of interstellar dust began to collect in a slightly hotter region of the solar system. The gravitational attraction between these particles began to draw them closer and closer to each other. Since the density near the center of the cloud was constantly increasing, the kinetic energy of the cloud also increased. The outer parts of the dust cloud began to spiral around the center. Eventually, the gas in the center became so hot and dense that it condensed to form our sun, fusing its hydrogen particles into helium. The outer rings of space dust then began to condense at other key points around the sun, maintaining their orbital velocity but being held at a constant distance by the star's gravitational pull. These clouds of dust eventually condensed to form the planets and the asteroid belt. This explains why all the orbital paths of the planets are within a few degrees of the same plane. As for galaxies, just extrapolate that explanation to the next level, replacing the dust particles with stars. Mind-blowingly simple, right?
What two forces control a star?
The Sun's gravity is immense; at every moment, the combined gravity of all that mass is trying to crush the star down to a point. But the Sun is also very hot and very DENSE, and these forces, and the nuclear fusion explosions constantly happening within the Sun, force the Sun's mass to spread out into space. The Sun neither collapses nor explodes, because of the precise balance between the inward force of gravity and the outward forces of radiation and pressure.
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 force is responsible for holding the stars gases and dust together in a galaxy?
The answer is simple: gravity.
Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Yes, stars are born when gravity pulls gas and dust together from a nebula.

Such groups exist at different levels:* Star clusters * Galaxies * Galaxy clusters * Superclusters
What is a big assembly of stars gasand dust that is held together by gravity?
The top six levels of upper management of the company I work for. I was not sure about the stars, but the gas and dust gave it away.
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.
What is a group of stars that form when a lot of gases and dust come together?
A star cluster.
