The First Space Telescope and What Galileo Did With It

Ask an Expert Live

Presented Online

Galileo was not the first one to build a telescope, but he was the first to use it to view objects in the heavens. Join us on Facebook Live as space history curator David DeVorkin talks about how Galileo used what he saw through his early telescope as argument that the universe was not what we had always thought it was.  

Planning to attend in-person? Meet in the Explore the Universe gallery. 

Every Wednesday at 12:30 p.m. we will go live on the National Air and Space Museum Facebook page with an Ask an Expert talk. We’ll select a different aviation or space topic each week, and a Museum staff member will discuss the history, stories, or personalities related to a specific artifact or exhibition in the Museum. Tune in on Facebook Live each week to join the talk and ask our experts questions.
