Elliptical, Irregular, and Spiral
M87 is one of the most prominent galaxies followed by the elliptical galaxy Messier 49.
You can have dwarf elliptical 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.
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
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.
Elliptical galaxies are generally old but not very bright
elliptical galxies
They are elliptical galaxies.
