Why is the Hubble called the Hubble? That's because the astronomer Edwin Hubble discovered the modern view of the Universe using the largest and most powerful telescope on Earth in the 1920s. A critical part of that telescope is on display at the Museum. Come see it and learn how it was employed to discover (1) that galaxies exist, and (2) that they are all moving away from one another.
The Ask An Expert lecture series at the National Mall building is presented every Wednesday at noon. A Museum staff member talks to the public about the history, collection, or personalities related to a specific artifact or exhibition in the Museum.
