Yes. It all depends on how hot the stars are "burning" and what they are using for fuel. Stars can be red, orange, yellow, blue, white and brown. And of course collapsed stars can form black holes that can be detected through X-Ray and Hawking radiation.
they get their colors by the different stars in the galaxy
Spiral galaxy- young stars bluish Elliptical-old stars are red
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
different stars in different levels
Different colors of stars "usually" means different temperatures. I don't remember the temperature that each color corresponds with, but when stars are different colors it is usually due to their temperature.
Yes.
Yes!!! The galaxies are a collection of millions if not billions of stars.
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
well sea stars are different colors so they can sea who are its family members
Elliptical Galaxy The Elliptical Galaxy has mostly old stars and blue stars are new stars.
Our galaxy is a barred spiral galaxy. There is a bar of stars, like the diameter of a circle, from which the spirals emanate, so to speak.
