Population I (High metal content) stars are generally found in the arms of spiral galaxies, whereas population II (Medium metal content) are generally found towards the centre of the galaxies.
Population I stars (metal-rich stars) are common in the Milky Way's spiral arms; Population II stars are more common in the galactic halo.For more details, you may want to read the Wikipedia article on "Metallicity". Note that in astronomy, "metal" is an informal name for elements other than hydrogen and helium. This usage is quite different from the usage in chemistry.
The galaxy in which Earth is located is classified as a(n)
Yes, stars can exist outside of a galaxy. These stars are typically referred to as intergalactic stars, and they may have been ejected from their original galaxy due to interactions with other stars or galactic dynamics. Intergalactic stars are typically found in the space between galaxies.
That is a globular cluster. These clusters are spherical collections of stars that orbit around the center of a galaxy in its halo. They are typically made up of thousands to millions of stars that are much older than the stars found in the disk of the galaxy.
The oldest stars in a galaxy are usually located towards the centre. Also known as the bulge.
Population 1 stars are luminous. They include the Sun and are hot and young stars. These types are usually found in spiral galaxies. Population 2 stars are found in nucleuses of galaxies and globular galaxies. These stars are older and usually cooler than the population 1 ones.
a galaxy is a huge city of stars and the solar system is located in the milky way galaxy that's our galaxy!
they are located in the middle of the galaxy
All over the place.
The dust and gas located between stars in a galaxy is called the interstellar medium (ISM). This material plays a crucial role in the formation of new stars and planets within the galaxy.
out side technically it is not inside
A galaxy.
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
I think most of them are in the Milky Way galaxy, that's where our solar system is located.
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
Population I (High metal content) stars are generally found in the arms of spiral galaxies, whereas population II (Medium metal content) are generally found towards the centre of the galaxies.
