In 1912, a mathematical equation by Henrietta Swan Leavitt made it possible to measure great distances in space. Then in 1929, Edwin Hubble published a paper with data showing the Milky Way was not the only galaxy in our universe, and that all those galaxies were speeding through the cosmos. In between, dozens of astronomers and heaps of research built up to a complete redesign of how big we know our universe to be and what we think it looks like.

The National Air & Space Museum is bringing you some of those stories in this new episode of AirSpace (a podcast). Click here, for the latest stories.
