Irregular galaxies do not have a defined shape; they have an asymmetric and chaotic appearance. Unlike spiral or elliptical galaxies, which have well-defined structures, irregular galaxies are characterized by their lack of a recognizable form or symmetry. They often appear lumpy or knotty and can contain regions of active star formation. Their shapes can result from gravitational interactions with other galaxies, collisions, or the influence of dark matter.
