How are irregular galaxies created?

The irregular galaxies are thought to have been deformed by an uneven external gravitational force after originally being spiral and elliptical.

They are mostly filled with dust particles and gases.

Their inability to form symmetrical shapes when galaxies collide or approach one another and their gravitational forces interact could be another explanation for their irregularity.

They might not have reached the point of symmetry, which would be another, more convincing explanation.

A variety of processes can lead to the formation of irregular galaxies, such as mergers of smaller galaxies or the gravitational influence of massive nearby objects. These processes include interactions with neighboring galaxies, collisions between galaxies, and disturbances caused by tidal forces. These interactions can disrupt the regular structure of a galaxy and lead to the formation of irregular shapes.
