4 fun facts about irregular galaxies
Understand the Problem
The question is asking for four interesting and engaging pieces of information about irregular galaxies, which are a type of galaxy that does not have a distinct regular shape. This could involve their characteristics, formation, or interesting examples.
Answer
They don't fit other galaxy categories, contain a lot of gas and dust, are young, and often collide with larger galaxies.
- They don't fit into other galaxy categories like spiral or elliptical. 2. They have high gas and dust content. 3. They are among the youngest galaxies. 4. They often collide with larger galaxies.

More Information
Irregular galaxies are unique partly due to their chaotic shapes and the absence of familiar structures like spiral arms or central bulges. This can indicate recent gravitational interactions or distortions.
Tips
Despite their irregular appearance, assume their chaotic shape has astronomical significance, such as past collisions or gravitational interactions.
