The four groups of galaxies are put into groups by the way they look, Spiral galaxies like our vary own milky way have tentacle like arms that make a spiral, there are also barred spiral galaxies that have only two arms in which give it a bar like appearance like the sculptor galaxy. We also have the elliptical and irregular galaxies. Elliptical galaxies have an ellipsoid or.. egg shaped look to them, Irregular galaxies don't have a particular look to them .. its and odd galaxy for sure one that always looks different from other galaxy. So i would say there classes depend on how they look.. there characteristics.

∙ 14y agoGalaxies come in a number of forms and are very distant being that our own galaxy is 100,000 light years across, meaning traveling at the speed of light it takes one hundred thousand years to traverse [travel across], and then between our galaxy and others there are hundreds of thousands of light years. Generally, like stars, we use light wavelengths to determine the makeup, distance and speed of galaxies, whereas for the way they look we use varying wavelengths of energy, gamma rays, x-rays, infrared, ultraviolet and so on to get varying appearances of the distant objects and hopefully get a good idea of what they look like.

Which insurgent strategy characteristic includes well-organized unarmed auxiliary continuous operations along multiple lines of effort and highly-indoctrinated elements?
Protracted popular war includes well-organized unarmed auxiliary continuous operations along multiple lines of effort and highly indoctrinated elements.
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.

Which galaxies have a great many short spiral segments branching from the spiral arms?
This may refer to the so-called "flocculent galaxies". Perhaps it's the "multiple arm galaxies", which are sometimes put in with the flocculent type.
How is Eukaryotic DNA organized?
they are grouped into multiple chromosomes.
How are stars organized?
If you are asking about the "display" of stars signifying a General Officer of the US Military, they are arranged on the epaulet of the uniform in linear order for one through four stars. If a five star General of the Army, the stars are arranged in a circle.
How can I keep a small amount of school supplies easily accessible and organized for homework time?
A pencil box with multiple compartments will help to keep you organized.
What has the author Sandra Moore Faber written?
Sandra Moore Faber has written: 'Photometry of elliptical galaxies in multiple systems'
Why do the furthest galaxies appear less ordered and less organized than those you see near the milky way?
The further away they are, the further back in time you see them. Such distant galaxies are much younger than ours, which is also evidenced via their chemical evolution.
Is there another galaxy in a black hole?
supermassive blackholes can contain multiple galaxies, however, the wouldn't be recognizable because they would be super compressed into infinitely small points of matter
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
What color can the galexies be?
Galaxies vary in color and usually are multiple colors. This is due to each galaxy evolving and changing colors as they mature and die.
How are galaxies classiflied?
Large star clusters, made up of multiple arms, and usually shaped like a pinwheel. They contain billions of stars.
Define the term database?
A database consists of an organized collection of data for one or more multiple uses
