WebFeb 8, 2024 · We’re back to the Doppler effect. Finally. With this information, American astronomer Edwin Hubble was able to determine the distance to certain things that were thought to be nebulae in between stars in our own galaxy. Hubble measured some to be so far beyond the edge of our galaxy and proved they weren’t nebulae at all.
