"Miss Leavitt’s Stars Unlock the Universe"
How far away are the stars? In a time when women did the laborious and detailed tasks of analyzing the photographic images of stars, Henrietta Leavitt observed a pattern in the brightening and dimming of certain stars she analyzed. What did she find? The result was a powerful tool, now known as Leavitt's Law, which helps us answer this question. Presentation is free and may be enjoyed even if you are unable to attend the play, 'Silent Sky'. Suitable for teenagers and adults, but anyone may attend..
