it is a galaxy.
The gravitational force between two objects always acts to attract them together. Electrically charged objects can attract if they have opposite charges, or repel if they have the same type charge. Thus only gravity could have caused matter in the universe to condense together and eventually form stars and planets.
The Earth exerts the greatest gravitational force on you because it is the most massive object you are closest to. The Earth exerts a force equal to your weight. The other objects exert gravitational forces but are not very noticeable because they are either low in mass or separated from you by great distance.
The universe has billions of stars. My cat's name is Roo. Today I'm going to pick strawberries.
That the Milky Way is the only existing galaxy populated by millions of sun-like stars. It wasn't until Edwin Hubble's discovery of the Andromeda galaxy in 1922 that everything changed, where we, since his discovery, now know that there are billions of galaxies each containing hundreds upon billions of stars! EDIT: Now I registered! If you want to know more, feel free to contact me!
It means everything in the universe is temporarily, will cease to exist. Humans, animals, plants, stars, planets, moons, and the universe itself will die sooner or later in decades or billions of years from now.
It is a galaxy.
They form galaxies, galactic clusters, and galactic superclusters.
The star groups are galaxies, or possibly globular star clusters.
its a GALAXY!! is a gravitational pull the same thing as a gravitational attraction? well, if it isn't the same than this may b wring just to let you know!!
A huge collectio of stars, dust, and gas held together by mutual gravitational attraction
They are held there by their mutual gravitational attraction.

Any mass in the Universe exerts a gravitational attraction. This applies to black holes, as well as other objects such as galaxies, stars, planets, etc. This gravitational attraction never stops, no matter how far you go away. However, if you go very far away, the gravitational attraction gets insignificant for most practical purposes.Any mass in the Universe exerts a gravitational attraction.

A system of billions of stars held together by gravity is called a galaxy. The one we live in is called the Milky Way galaxy.
a cluster
There are billions of galaxies. Most stars are born in one galaxy but others are pulled in by the huge gravitational forces of the black hole in the centre.
Nebula are an accumulation of gas particles. Bearing in mind that there untold billions of atoms in the cosmos. Any two atoms have a gravitational attraction between them. they come together, thus attracting more gas particles by gravitational attraction. These gas particles become so crowded that they begin to glow, (the nebula). The analogy, is a dance hall/disco; maybe two people will statr to dance. Eventually a lot more people arrive on the dance floor, and it becomes hot and crowded. Under further gravitational attraction these hot crowded gas particles keep accumulating into a hot glowing ball. Because partiucles are now so crowded nuclear fusion starts, and releases energy. Hence a Star/Sun. Because this process takes billions of years we do not instantaneously see it going on. NB All stars are nuclear reactors in space.
