Explain How Elliptical Irregular and Spiral Galaxies Different
Describe the main distinguishing features of spiral elliptical and irregular galaxies. Unlike the additional spiral tightness classification of barred and typical spiral galaxies elliptical galaxies have a more specific classification of the numbers 0 through 7.

Galaxies come in a wide variety of shapes and sizes.
. Elliptical galaxies lack the swirling arms of their more well-known siblings spiral galaxies. Typically irregular galaxies have lower masses and luminosities than spiral galaxies. Typically irregular galaxies have lower masses and luminosities than spiral galaxies.
There are different shapes of galaxies. More older stars than newer. Galaxies in addition to great variations in size come in 3 basic morphologies.
Like snowflakes every galaxy is unique in its way. An elliptical galaxy is the most common type of galaxy has a roundish shape and demonstrates little or no star formation. So-called irregular galaxies lack bulges and can come in a wide variety of shapes.
When galaxies merge the process destroys gasses needed to form new stars. Stars move due to gravity interactions in all. Elliptical Galaxies looks like an sphere shape.
An irregular galaxy is a galaxy with no defined shape that has very young stars. Elliptical galaxies are normally formed after spiral galaxies merge. Elliptical appear to be elongated while irregular galaxies have no identifiable shape.
The Hubble classification scheme uses the letter E to identify elliptical galaxies. Maybe theyll look like nice well-rounded ellipticals someday but at the moment these developing unions appear disorganized and distorted. There are four different types of galaxies.
Has a halo bulge and a disk. Spiral elliptical irregular and ring. They contain both young population I stars and old population II stars.
Spiral galaxies have signature arms which wrap around the galactic disk. Within each of these groups there also exist subgroups. A disk galaxy also called a spiral galaxy is shaped like a fried egg said Cameron Hummels theoretical astrophysicist at Caltech.
Spiral pinwheels such as the Milky Way or Andromeda elliptical oval shaped and irregular no dominant geometric shape. In spirals its the disc that is largely made of Population I stars or blue stars while the bulge which is devoid of gas and dust has Population II stars or red stars to its credit. Irregular galaxies often appear disorganized and many are undergoing relatively intense star formation activity.
A spiral galaxy consists of a spinning flattened disk with arms that rotates very fast. The formation is an elliptical mass of stars without any arms. That also explains why elliptical galaxies are largely made up of old red stars Population II stars while spiral galaxies have both old stars and young blue stars Population I stars.
Spiral Galaxies looks like a spiral. Elliptical galaxy is a type of galaxy having an approximately ellipsoidal shape and a smooth nearly featureless brightness profile. The main types are spiral barred spiral elliptical lenticular and irregular.
Elliptical galaxies are shaped like elipses. Unlike flat spiral galaxies with organization and structure they are more three-dimensional without much structure and their stars are in somewhat random orbits around the center. Its thought that spiral galaxies burn through the star-forming fuel and eventually become elliptical galaxies.
Irregular galaxies often appear disorganized and many are undergoing relatively intense star formation activity. Irregular galaxies are all the others that dont fit the two classifications above. They contain both young population I stars and old population II stars.
Spiral galaxies have arms spiraling out from the central bulge of the galaxy and contain newer stars and has more gasses to form new stars. The 0 represents the most round elliptical galaxy and 7 means that the galaxy is very ovular. Spiral galaxies like ours have arms that make them look like a spiral.
Unlike flat spiral galaxies with organization and structure they are more three-dimensional without much structure and their stars are in somewhat random orbits around the center. Furthermore scientists have observed some galactic mergers that are currently in progress. Instead they bear the rounded shape of an ellipse a stretched-out circle.
For example spiral galaxies are divided into normal spirals and barred spirals. Shaped as an ellipse or sphere. Irregular Galaxies can take on any weird shape.
As the name implies irregular galaxies are all quite unique. An elliptical galaxy is a type of galaxy having an approximately ellipsoidal shape and a smooth nearly featureless brightness profile. Scientists believe that spiral galaxies are younger than elliptical galaxies.
Mostly they have a blobby shape.
