The most widely recognized system for categorizing the general shapes that galaxies form is credited to Edwin Hubble. Although each galaxy has a unique shape, he found they could be categorized into several shapes with common features. There were the rather featureless ellipticals, and then the spiral galaxies including spirals with bars (central bar-shaped concentrations of stars like our own Milky Way); and the lenticulars which have a flat disk shape with a central bulge but no spiral arms, and also irregulars, with odd or more random shapes that fell outside these common ones. Other shape (morphology) classification systems refined or extended these basic shapes, the classification varying because of a different placement of emphasis upon specific features such as star types or densities, presence of rings, and so forth.

What causes different crystal shapes?
Crystals are made from molten magma that cools causing silicate minerals to crystallize. The different crystal shapes form differently as the magma cools at different rates.
Edwin Hubble categorized galaxies according to their?
Shape, or morph. The spiral galaxies, elliptical galaxies, lenticular, barred spiral, and irregular galaxies all are different shapes or morphs of galaxies, and so they are classified differently.
Irregular galaxies are different from elliptical and spiral galaxies because?
Because irregular galaxies have no definite shape.
What determines the shape of a galaxy?
That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.That is related to their past history.

What do clusters of galaxies form?
A collection of from two to several hundred galaxies which are much more densely distributed than the average density of galaxies in space.
What holds stars together to form shapes of galaxies?
GRAVITY!
Are all galaxies the same size?
All galaxies are different sizes and mainly four different shapes,spiral,barred spiral,elliptical and irregular
Are all of the galaxies in the universe the same?
No. They come in different sizes and different shapes, and have other differences as well.
What shapes do irregular galaxies have?
Irregular galaxies have no discernible shape.
What shapes of galaxies do contain H II regions?
Spiral and irregular galaxies.
What does different galaxies look like?
Different galaxies have different shapes and sizes according to how many stars are in each. The best way to actually see them "up close" is by looking at images (some amazing ones are taken by the Hubble telescope).
Why do the same galaxies can appear to have different shapes to different observers?
The reasons are the same as why a bird's eye view of your house would be different from the front or side elevations.
What are the 4 main galaxy shapes?
There are various ways of categorising galaxies, often based on Edwin Hubble's work on the shapes galaxies. Classifications often give the four main types of galaxies as: Spiral (including barred spiral), Elliptical, Lenticular and Irregular.
Galaxies are classified by their shape what are they called?
There are three types of galaxies, all of which are the same, with the exception of their shapes. There are the Elliptical galaxies (football-shaped) the Spiral galaxies (like the Milky way; vortex-shaped) and Irregular galaxies (all shapes other than spiral and football shaped).
Do all 100 billion galaxies come in all shapes sizes and colors?
Yes. All 100 billion galaxies come in all shapes, sizes, and colors.
Will astronomers classify all the shapes of the 100 billion galaxies in the universe?
There's an impossible way to classify all the shapes of 100 billion galaxies in the universe.
Will astronomers classify all the shapes of 100 billion galaxies in the observable universe?
Someday astronomers may have classified all the shapes of 100 billion galaxies in the observable universe.
