You can also distinguish them by the types of stars - older stars versus younger stars, and stars of different "metallicity".
Vast collections of stars are called galaxies.
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.
the ones that are cool like meh
jupiter because the atmosphere has to much sunlight wich connects to earth death of a meteor
Population I stars
We see the stars in the sky, from our perspective of being here on the Earth. Stars are grouped into galaxies of billions of stars, and there are vast almost-empty spaces between the galaxies.
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
All stars and galaxies are in the universe.
its called a globular cluster
Yes, there are stars between galaxies. When there are collisions or interactions between galaxies, stars can be ripped out of the galaxies. These stars will then wander into space between galaxies. Such stars have been observed with the Hubble Space Telescope. Taken from http://curious.astro.cornell.edu/question.php?number=384
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
