Elliptical galaxies are made of old stars and not very much gas or dust.
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.
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.
They're elliptical shaped and the typically have a red center because of all the red giants that form in this type of galaxy.

No. Elliptical galaxies are some of the oldest galaxies.They are also called early galaxies. The elliptical galaxies are made of low massed stars, a sparse interstellar medium and very low star forming characteristics.
Yes. Some giant elliptical galaxies contain tens of trillions of stars.
yes they can and if that happens the galaxy will be destroyes :)
M87 is one of the most prominent galaxies followed by the elliptical galaxy Messier 49.

Galaxies in the universe have different names based on their shape and structure. Some common types of galaxies include spiral galaxies, elliptical galaxies, and irregular galaxies. Each type has its own unique characteristics and features.
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
Some elliptical galaxies appear to be perfect spheres due to their isotropic distribution of stars and lack of significant rotation. This spherical shape results from the gravitational forces acting uniformly in all directions, leading to a smooth, rounded appearance. Additionally, the random motion of stars within the galaxy contributes to this uniformity, as there is no preferred axis of rotation, unlike spiral galaxies. Consequently, these elliptical galaxies maintain a more symmetrical and spherical structure.
