The brightness of normal galaxies is mainly due to stars; quasars are believed to get most of their energy output from the black hole at their center.

What kinds of galaxies are bright cores and spiral galaxies?
a spiral galaxy is what you call a "kind" or classificationfor example the milky way galaxy is a spiral galaxy
Do spiral galaxies have very bright centers and little gas and dust?
No. They have a spiral shape.,
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
What galaxies are smaller with many bright young stars and lots of gas and dust for star formation?
Spiral Galaxies
What are the types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
What is the type of galaxy that has a nucleus of bright stars with arms that circles around it?
All types of galaxies have a core with a high star density. All galaxies with "arms" are called Spiral Galaxies, of which there are sub-types related to the shape of the arms.
How many galaxies are spiral?
Approximately 60% of all galaxies are spiral
How many barred spiral galaxies there?
It's not known to any degree of accuracy, but about 66% of all spiral galaxies are barred and about 60% of galaxies in the local Universe are spiral galaxies.
How many types of spiral galaxies are there?
Yes. There are two types of spiral galaxies: "S" (normal spiral) and the less common "SB" (barred spiral, with an elongated center).
What are the 3 common galaxies?
galaxie 1, 2, 3, 4 and 5
How are galaxies classifyed?
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
What is the shape of a Spiral Galaxy?
Spiral galaxies are named for the (usually two armed) spiral structures that extend from the centre into the disk.The spiral arms are sites of ongoing star formation and are brighter than the surrounding disk because of the young, hot stars.See related link for a pictorial representation.
