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.
no there irregular it comes from the name irregular because of the shape irregular
Irregular ones
Irregular galaxies have no discernible shape.
Irregular ones!
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
They are ALL galaxies.
Irregular galaxies are believed to have been spiral or elliptical galaxies in the past, which have been distored through gravitational pull of neighboring galaxies.
Because irregular galaxies have no definite shape.
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
irregular galaxies
Yes, irregular galaxies are all shapeless. None of them have a distinct shape.
Spiral,elliptical,and irregular galaxies
There are at least 5 billion irregular galaxies in the universe.
