Lecture 24: The Realm of the Nebulae
Update: 2006-02-08
Description
How did we come to understand that the Milky Way was just one of
billions of other galaxies in a vast Universe? This lecture
reviews the history of how we came to recognize that the spiral nebulae
were, in fact, other milky ways like our own: vast systems of
100s of billions of stars located millions of parsecs away. The
key to understanding their nature was finding the distances to the
spiral nebulae compared to the size of our Galaxy.
Recorded 2006 February 8 in 1008 Evans Laboratory on the Columbus campus
of The Ohio State University.
