Thirteen billion years ago, the gas and dust particles that eventually became our Milky Way were whizzing around in every direction. Despite the wild motion of its parts, the galaxy as a whole was rotating about an axis. So why did the Milky Way, like most galaxies, become flat, and not spherical like stars and planets? Scott Hershberger explores the ever-evolving structure of our galaxy. [Directed by Josh O'Caoimh, Mikai Geronimo, narrated by Addison Anderson, music by Salil Bhayani, cAMP Studio].
