Disc galaxy

A disc galaxy is a type of galaxy that looks like a big pancake spinning around in space. Just like how you can spin a frisbee around in the air, these galaxies spin too! They have lots of stars and dust and gas all stuck together in this flat disc shape.

The middle part of the galaxy is called the nucleus, and it's like the belly button of the galaxy. The nucleus is the center of the galaxy where lots of activity happens, like stars being born and old stars exploding.

The edges of the galaxy are called the outer disk. This is where there are fewer stars, and there's a lot of empty space between them. Sometimes, there are also spiral arms that stick out from the outer disk, kind of like a pinwheel or a hurricane. These are also places where new stars are born.

Disc galaxies are pretty common in the universe, and there are lots of different sizes and shapes of them. They're kind of like big families of stars and gas and dust, all spinning around together and making beautiful shapes in the sky.
