Why do some elliptical galaxies appear to be perfect spheres?
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.
Is it true that elliptical galaxies are sometimes called dwarf galaxies?
You can have dwarf elliptical 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.
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
Are there at least 15 billion elliptical galaxies in the universe?
There are at least 15 billion elliptical galaxies in the universe.
What are the 3 common galaxies?
galaxie 1, 2, 3, 4 and 5
