🌌What makes an irregular galaxy irregular? ✨It’s usually small and has a chaotic appearance that’s likely due to recent disturbances. Some acquire their unusual shapes from galactic encounters: when galaxies pass near each other or collide, gravity pulls and distorts their shapes, often resulting in long “tails” of stars and gas.
