How Big is the Universe?
<p>How big is the universe? And how do we know? It's a question that puzzled astronomers for centuries. They had no way to measure distance in space - until Henrietta Leavitt showed them how. Henrietta Leavitt was a "computer" in the 19th century, before there were computers, and she made an incredible discovery that would help change the way people thought about the universe - forever. Modern-day astronomer Karen Masters helps us tell her remarkable story. </p> <p><br></p> <p>If you like this episode, you'll love our free audio course, "Cataloging the Universe" where you'll learn much more about how Henrietta Leavitt's discovery made a big difference in astronomy - plus, you'll become a skywatcher yourself!
