Our Milky Way galaxy is a spiral galaxy. It evolved into its flat disk shape over billions of years. But astronomers have discovered a distant and young galaxy that has a remarkably similar shape.

Host Melissa Hoffman of the National Radio Astronomy Observatory talks about how this young galaxy was discovered, and what it tells us about our own Milky Way.
