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 shapes do irregular galaxies have?
Irregular galaxies have no discernible shape.
What galaxies in the universe are irregular galaxies?
Irregular ones!
What are the types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
How are spiral and elliptical irregular and irregular galaxies alike?
They are ALL galaxies.
How do irregular galaxies become irregular?
Irregular galaxies are believed to have been spiral or elliptical galaxies in the past, which have been distored through gravitational pull of neighboring galaxies.
How are galaxies classifyed?
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
Why are they called weird galaxies?

Are irregular galaxies shapeless?
Yes, irregular galaxies are all shapeless. None of them have a distinct shape.
The types of Galaxies?
Spiral,elliptical,and irregular galaxies
Which galaxy is bigger a elliptical or irregular?
Elliptical galaxies are typically larger than irregular galaxies. Elliptical galaxies are shaped like ellipsoids and often contain more stars and stellar mass compared to irregular galaxies, which have a more irregular and chaotic shape and structure.
