Because of their age, elliptical galaxies are believed to have older stars and less gas and dust in their insterstellar medium than other types of galaxies, and thus their nebulae are less common. However, nebulae are presumed to exist in almost all galaxies; and some recent observations hint that the central black holes of elliptical galaxies may tend to preserve interstellar gas by preventing it from cooling enough for star formation.

Which galaxy is bigger a elliptical or irregular?
Irregular galaxies are different from elliptical and spiral galaxies because?
Because irregular galaxies have no definite shape.
What color do elliptical galaxies tend to be and why?
Elliptical galaxies have an abundance of low mass stars or red dwarfs.
What are some physical characteristics of elliptical galaxies?
Elliptical galaxies are made of old stars and not very much gas or dust.
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.

Is it true that elliptical galaxies are sometimes called dwarf galaxies?
You can have dwarf elliptical galaxies.
Who proved that there are galaxies besides the milky way?
Hubble, in his studies of Nebulas which turned out to be galaxies.
What is three dimensional galaxies that can be shaped like a football that can be shaped like a football?
I think elliptical galaxies are the galaxies you are referring to. Scientist normally describe them as a flatted disk shape. These galaxies contain mainly older stars.
How are galaxies classifyed?
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
Which galaxy is bigger a elliptical or irregular?
What is one way that an elliptical galaxy differs from the other types of galaxies?
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
What are similarities between elliptical and spiral galaxies?
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
Are elliptical galaxies very bright and old?
Elliptical galaxies are generally old but not very bright
Do elliptical galaxies have gas and dust?
elliptical galxies
What are football shaped galaxies called?
They are elliptical galaxies.
The types of Galaxies?
Spiral,elliptical,and irregular galaxies
What are the 3 common galaxies?
galaxie 1, 2, 3, 4 and 5
