Elliptical galaxies have an abundance of low mass stars or red dwarfs.
Because they have a high proportion of low mass stars, or red dwarfs.
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.
Because irregular galaxies have no definite shape.
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.
Elliptical galaxies are made of old stars and not very much gas or dust.
Elliptical Galaxies.
You can have dwarf elliptical galaxies.
Elliptical Galaxies.
Yes, that is correct. Elliptical galaxies are characterized by their elliptical or egg-shaped appearance and lack spiral arms of interstellar gas and dust. Unlike spiral galaxies, which have a flattened disk shape with spiral arms, elliptical galaxies have a more rounded or elongated shape. They are composed mainly of older stars and contain little to no ongoing star formation. Elliptical galaxies also tend to have less interstellar gas and dust compared to spiral galaxies.
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.
Elliptical galaxies have a red color because the stars in them are older and cooler. An example of an elliptical galaxy is Maffei 1.
spiral galaxies (ours), irregular galaxies, and elliptical 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.
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
