Irregular galaxy
A galaxy that lacks a regular shape is called an irregular galaxy. Irregular galaxies do not have distinct spiral arms or a central bulge like spiral or elliptical galaxies. They often have a chaotic appearance with no clear structure.
A galaxy that does not have a regular shape is classified as an irregular galaxy. Unlike spiral or elliptical galaxies, irregular galaxies lack a defined structure and often have a chaotic appearance. They can contain a mix of young and old stars, gas, and dust, and are typically found in regions with gravitational interactions or near other galaxies.
A regular galaxy refers to a type of galaxy that exhibits a distinct, well-defined shape and structure, typically categorized as elliptical or spiral. These galaxies have a uniform distribution of stars and gas, with a clear central bulge and disk in spiral galaxies, or a smooth, featureless appearance in elliptical galaxies. Regular galaxies contrast with irregular galaxies, which lack a coherent shape and often have chaotic structures. Examples of regular galaxies include the Milky Way (a spiral galaxy) and M87 (an elliptical galaxy).
It is known as an irregular galaxy. A few different Classifications are : Irr L (some structure) Irr LL (No visible structure) Also Dward Irregulars : DL DLRRS (Low Metallicity)
It depends what shape the galaxy has.
A galaxy that does not have a regular shape is classified as an irregular galaxy. Unlike spiral or elliptical galaxies, irregular galaxies lack a defined structure and often appear chaotic in form. They are typically rich in gas and dust, which can lead to active star formation. Examples of irregular galaxies include the Large and Small Magellanic Clouds.
The shape of the Milky Way (our galaxy) is the shape of a spiral.
An Irregular Galaxy is a galaxy that has no shape or form as defined by the classes of the "Hubble sequence" An Amorphous galaxy is a galaxy that has neither spiral nor elliptical in shape as defined by "The Atlas of Peculiar Galaxies". See related links for pictorial representation
First of all, it's a spiral galaxy, not an spiral galaxy. Second, a spiral galaxy would have a spiral shape, obviously.
Our galaxy is a spiral galaxy because it is spiral in shape.
A spiral galaxy has the shape of a pinwheel. Our solar system is in a spiral galaxy that we call the Milky Way.
