Irregular galaxies<span> get their odd shapes in many ways.
One way </span>irregular galaxies <span>are </span>formed<span> is when </span>galaxies collide/come close to one another, and their gravitational forces interact.<span> Some </span>irregular galaxies<span> were once spiral or elliptical </span>galaxies<span> but were deformed by these uneven external gravitational force.
</span><span>Another source of </span>irregular galaxies<span> may be very young </span>galaxies that have not yet reached a symmetrical state.
