Where Do Galaxies Come From?

Galaxies are like big groups of stars that formed from clouds of space stuff.

Imagine you're playing with a bag of legos, that’s kind of what happened in space. A long, long time ago, there were huge clouds made of gas and dust floating around the universe. These clouds were like giant, fluffy pillows, but instead of being soft, they were full of stuff that would eventually become stars.

One day, these clouds started to collapse, just like when you push your hand into a pillow and it squishes down. As they collapsed, parts of them began to spin really fast, and from that spinning, stars were born.

But not all the cloud became one star, some parts spun off and formed smaller groups, which became galaxies. It's like when you push your hand into a pillow and it squishes down, but some pieces come flying out in different directions, each making their own little pile of legos.

So galaxies didn’t just appear from nowhere, they were made from the same space stuff that made stars, all starting with a big, fluffy cloud.
