Because of gravity. Only gravity can pull large clouds together with enough force to overcome gas pressure.
New stars form from the interstellar gas and dust; mainly hydrogen and helium.
A nebula (a bright region of expanding gas) is often the visible remnant of a supernova explosion. The gas is not nearly as dense as it appears but has enough matter to block light coming from behind it, or from within it. Nebulae often react with clouds of interstellar gas to create new proto-stars.

stars are born from interstellar gas clouds, shine by nuclear fusion and then die

No. The vast majority of stars in our galaxy are too far away to see, and many are hidden behind clouds fo gas and dust.
We cannot see the center of the Milky Way galaxy, because it is hidden by clouds of interstellar gas. However, there is reason to believe that there are no stars at the center of the Milky Way, but only a supermassive black hole.
All stars are formed the same way, by the condensation of large clouds of interstellar gas.
Because of gravity. Only gravity can pull large clouds together with enough force to overcome gas pressure.
We believe that stars form at the CENTERS of rotating interstellar gas clouds.
alot of different colors; it looks like a galaxy and has stars; stars form in a nebula, from collapsing clouds of interstellar gas and dust
New stars form from the interstellar gas and dust; mainly hydrogen and helium.
No. Many stars are too dim and to distant to be seen even with highly advanced telescopes, and many others are hidden behind clouds of gas and dust.
