Cosmos:elementary | What creates a spiral structure of galaxies? @Cosmos_elementary | Uploaded May 2020 | Updated October 2024, 33 minutes ago.
Why do spiral galaxies have this beautiful spiral structure? We are going to talk about both grand design and flocculent spiral galaxies, what spiral arms are and how they form.
