What is an irregular galaxy?
Quick Answer
An irregular galaxy is a galaxy without a clearly defined spiral or elliptical shape. Many look distorted because of gravitational interactions or collisions.
The Full Story
Irregular galaxies do not fit neatly into the spiral or elliptical categories of galaxy shape. Some are small, gas-rich systems with active star formation, while others appear chaotic because of past collisions or tidal interactions. The Large Magellanic Cloud is a nearby example often described as an irregular galaxy. Their uneven structure makes them valuable for studying how galaxies are shaped by gravity and environment. They can contain intense regions of star birth despite their messy appearance.
