How are population II stars different than the Sun a population I star?
Population II stars are lower in "metals" than population I stars. By metals, astronomers mean anything other than hydrogen and helium.
Which are the oldest stars in the Milky Way population 1 or 2 stars?
Population II stars are the oldest in our Milky Way. Population III stars were the first stars in the Universe, but have yet to be discovered. See related question
How do Population One and Population Two stars compare to each other?
Population I stars have more metals (heavier elements), and are generally younger, than the Population II stars. It is postulated that there are still older Population III stars, that have even less metals and are even older, but none have been discovered yet.
Where are the Population One and Population Two stars located in the Milky Way Galaxy?
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.
What population stars are found in a sprial 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.

Population II stars are lower in "metals" than population I stars. By metals, astronomers mean anything other than hydrogen and helium.
How are population 1 stars and population 2 stars different?
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.
What are the two population stars in the milky way?
Population I stars are young and luminous like the Sun. Population II stars consist of globular clusters that are generally much older.
Which are the oldest stars in the Milky Way population 1 or 2 stars?
Population II stars are the oldest in our Milky Way. Population III stars were the first stars in the Universe, but have yet to be discovered. See related question
The brightest stars in aging globular clusters will be?
The hottest stars. Generally, globular clusters contain mainly old stars, population II stars
Where can young metal-rich stars be found in the milky way?
The so-called "Population I" stars are found in the galactic suburbs, which is where we live. Population II stars are concentrated toward the galactic bulge.
How do Population One and Population Two stars compare to each other?
Population I stars have more metals (heavier elements), and are generally younger, than the Population II stars. It is postulated that there are still older Population III stars, that have even less metals and are even older, but none have been discovered yet.
What are some differences between pop I and pop II stars?
Population I is younger and has more heavy elements. Population II is older and is almost entirely hydrogen and helium.
Where are the Population One and Population Two stars located in the Milky Way Galaxy?
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".

What is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars called?
The Galactic halo is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars.
What population stars are found in a sprial 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.
Suppose you discovered a star made purely of hydrogen and helium how old do you think it would be?
population II stars
