What is the typical state of an irregular galaxy in terms of structural stability?

Answer

It often signals a transient state due to recent gravitational encounter or disruption

Irregular galaxies often lack defined structure because they have undergone extreme gravitational disruptions, or they are simply too young to have settled. Their non-symmetrical forms are frequently the immediate aftermath of tidal forces pulling out streamers of material.
