What is the shape of a small galaxy with older stars very little dust and a bright center?

A small galaxy with those characteristics would be a dwarf elliptical galaxy, such as M32 (a companion to Andromeda). Most elliptical galaxies are larger than average galaxies, and some are among the largest, containing as many as a trillion (1012) stars.
Elliptical galaxies generally have few young stars and more dust when compared to spiral galaxies such as the Milky Way or Andromeda.

∙ 12y agothat's got to be "Starburst Galaxies"
Starburt is a generic term to describe a region of space with abnormally high rate of star formation..in astronomy. For eg, an open cluster maybe having quite a high rate of star formation but that is not star burst. A galaxy with high rates would be a starburst galaxy.
For eg, The Cigar Galaxy (M82) in Ursa Major, 12 million light years away is a star burst galaxy, the star formation rate is 10 time more than that of the Milky Way.

Is a galaxy shaped like a ball and containing only older stars most likely spiral galaxy?
It ture

Is there mountain center of La France?
the mountain range 'Massif Central' is just south of the center of France. These mountains are older than the Alps and lower.

I watch spongebob lol :)
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
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.
Why are older stars in the center of a galaxy?
Because newer stars are forming at the outer edges, and because the gravitational pull is stronger for the older stars.
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
A small galaxy with stars very little dust?
A small galaxy with stars and very little dust is commonly called an elliptical galaxy. Elliptical galaxies are extremely small and typically made up of smaller and older stars.
Which is older the solar system or the galaxy?
The galaxy is older than our Solar System.
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 type of galaxy tends to be older?
Generally, an Elliptical galaxy is the oldest type of galaxy.
