Question: how was the galaxy made?

Hey Starz!

We really don’t know how all the different galaxies were formed and how they made the many shapes that we see today. We have a few ideas though! The Big Bang happened about 14 billion years ago. Just after that collapsing gas and dust clouds might have lead to the formation of of the galaxies.

There are scientists who are trying to recreate the Big Bang by smashing particles together to see what happens. They hope that by doing that they will understand more about what happened at the start of the universe!
