What are galaxies that have very bright centers and very little dust or gas called?
Galaxies with very bright centers and very little dust or gas are called elliptical galaxies. These galaxies are primarily made up of old stars and have a smooth, ellipsoidal shape with little ongoing star formation.
What types of galaxies tend to be made up of very old stars and contain very little gas and dust matter?
elliptical
What is a galaxy that is shaped like an oval?
elliptical galaxies
What are some physical characteristics of elliptical galaxies?
Elliptical galaxies are generally round or oval in shape, lacking the distinctive spiral arms seen in spiral galaxies. They typically have a smooth and featureless appearance, with older star populations and little ongoing star formation. Elliptical galaxies also tend to be more massive and contain mainly older stars.
Why some elliptical galaxies are lens shaped where as others are quite spherical?
Very lens-shaped elliptical galaxies have a high amount of reddish stars. Hence both their shape (the "spiral arms" have pulled inward over time) and the color of the stars implies they are very old galaxies. Spherical galaxies - I'm not up enough on that topic, so I will leave that part of the answer to another.
Is this true an elliptical galaxy has mostly old stars?
Both - all galaxies contain young and old stars.
What determines the shape of a galaxy?
That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.That is related to their past history.

What kind of galexies are there?
There are generally three types of galaxies: spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies like the Milky Way have a disk shape with arms of stars spiraling out from a central core. Elliptical galaxies are shaped like ellipses and contain mostly older stars. Irregular galaxies have a less defined shape and tend to have a mix of young and old stars.
A galaxy that has a shape similar to a football is a?
elliptical galaxy. These galaxies are often round or elongated in shape, resembling a football or an elongated sphere. They are composed mostly of old stars and lack the distinct spiral arms seen in spiral galaxies.
What galaxies have mostly old stars without a lot of active star formation?
The milky way. and if this is incorrect I'm sorry. and if it is right like my answer please?
What types of stars do elliptical galaxies usually have?
Yes. However, the current rate of star creation is less than when the galaxies were younger.Yes. However, the current rate of star creation is less than when the galaxies were younger.Yes.

Compare and contrast the three types of galaxies?
Galaxies that appear to have a bulge in the middle and arms that spherical outward, like pinwheels, are spherical. Elliptical galaxies look like round or flattened balls. Galaxies that do not have regular shapes are known as irregular galaxies.
