Galaxies come in different shapes, some are spiral, and others are elliptical.
Imagine you're playing with a toy car on two different tracks. On one track, the road winds around like a spiral staircase, that's what a spiral galaxy looks like. It has long, swirling arms that twist out from the center, kind of like a pinwheel. These galaxies are full of bright stars and sometimes have lots of gas and dust, which helps new stars form.
Now imagine another track, it’s more like a smooth oval path with no sharp turns. That's an elliptical galaxy. It looks more like a squashed circle or a football. These galaxies don’t have the swirling arms, and they usually have older stars that are not as bright.
What Makes Them Different?
- Spiral galaxies often look lively and full of activity, like a busy playground.
- Elliptical galaxies feel more calm and quiet, like a peaceful park on Sunday morning. Galaxies come in different shapes, some are spiral, and others are elliptical.

Examples
- Imagine a spiral galaxy like a whirlpool with arms full of stars, and an elliptical galaxy like a squashed oval without distinct arms.
- Spiral galaxies are like busy cities with lots of star formation, while elliptical galaxies are more like quiet towns with older stars.
- You can see the arms of a spiral galaxy from Earth, but elliptical galaxies look smooth and round.
