Galaxies are primarily classified into three main categories: spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies, like the Milky Way, feature a flat, rotating disk with spiral arms and a central bulge. Elliptical galaxies are more rounded and lack the distinct structure of spirals, often appearing as smooth, featureless ellipsoids. Irregular galaxies do not fit into the other two categories and have an irregular shape, often resulting from gravitational interactions or collisions with other galaxies.
What else can I help you with?
Who found the galaxies?
who discovered the galaxies who discovered the galaxies
What are the types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
How did Edwin hubble sub-categorize spiral galaxies?
Hubble devised subcategorization for spiral galaxies first based on whether the galaxy exhibited a bar and then how well the spiral arms were defined. The classes are designated as Sa, Sb, and SC with the Sa class being the most tightly wound. A capital B designation after the S indicates the presence of a bar as well.
What is the possessive form of galaxies?
The possessive form for the plural noun galaxies is galaxies'.Example: Their galaxies' paths do not coordinate.
What galaxies are sometimes called dwarf galaxies being typically smaller than spiral galaxies?
Elliptical galaxies are sometime called dwarf galaxies.
What are the fifteen galaxies?

Are galaxies harmful?
no galaxies are not harmful
How are galaxies classifyed?
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
Is it true that elliptical galaxies are sometimes called dwarf galaxies?
You can have dwarf 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.
Why are irregular galaxies irregular?
An irregular galaxy is a galaxy that does not have a regular shape, like a spiral or an elliptical galaxy.[1] The shape of an irregular galaxy is uncommon - they do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.[2] Collectively they are thought to make up about a quarter of all galaxies. Most irregular galaxies were once spiral or elliptical galaxies but were deformed by gravitational action. Irregular galaxies also contain abundant amounts of gas and dust.
What galaxies are there?
there are a few kinds of galaxies in our universe.
