On April 24, Haverford’s Public Observing Astronomy Program proudly hosted the an Astronomy Night in as part of the Philadelphia Science Festival. Over 200 guests packed into the Strawbridge Observatory and adjacent fields for a variety of astronomy-related activities.
Before sunset, two Haverford students led Solar System Walk, scaled down so the sun was the size of a basketball. The tour illustrated the vast expanse of our solar system; the group proceeded across the athletic fields without reaching outermost planets.
Inside, younger guests built their own mobiles, while others mastered four levels of astronomy trivia. Older visitors participated in virtual observing through Observing With NASA (mo-www.harvard.edu/cgi-bin/OWN/Own.pl) and were excited to look at images from anything up in the sky that night. A cloud chamber demonstration helped visitors visualize the paths of high energy particles in the upper atmosphere. Another creative demo utilized marbles and fabric to illustrate Einstein’s Theory of general relativity.
