Because newer stars are forming at the outer edges, and because the gravitational pull is stronger for the older stars.

What is a cluster of tightly packed of older stars called?
It is called simply a "globular cluster". Another possibility: The closely allied stars at the center of a galaxy tend to be older, redder stars than those in the outlying arms of the galaxy.
Which type of galaxy mostly consists of a collection of older red stars that are located in the center with blue and white stars located in the outer regions?
A Spiral Galaxy
How are the stars distributed within this kind of galaxy.?
The center of the elliptical galaxy is very dense with many stars, and density decreases farther out.
What are straight branches of stars projecting from the center of galaxy?
Generally older stars. Most, if not all galaxies have a supermassive black hole at their centre.
Why are older stars located at the center of the spiral Galaxy while younger stars make up the arms of a spiral Galaxy?
Older stars are generally towards the centre of a galaxy as they will be the first to accumulate around the galactic centre. Because they are older, there is less "free" hydrogen, so new star formation will occur wherever, there is enough matter to form a new star. This generally is around the outer edges of a galaxy.

How is the age of the galaxy determined?
By analysing the oldest stars found.The older the star, the older the Galaxy.
What galaxy cotains mostly older stars with a red color?
Elliptical Galaxy
What galaxy contains mostly older stars with red color?
Elliptical galaxies have a red color because the stars in them are older and cooler. An example of an elliptical galaxy is Maffei 1.
What is a group of stars with black hole in center?
A galaxy.
What are young galaxy stars that have giant black holes at the center?
It's not "galaxy stars", but galaxies, that have the black holes at their center.All, or most, galaxies have a giant black hole at their center.
What type of galaxy has giant bright new stars around the edges and older stars in the middle?
a spiral galaxy like the milky way
