Like prisms, the special glasses break light up into its individual colors so that spectators can see the fireworks in a more scientific way. Astronomers use technology similar to that of the eyeglasses in their research labs and in telescopes to determine the composition of extremely distant objects, such as planets and star clusters.

"Seen through the glasses, each explosion during the fireworks show registers as several lines of color," said Brendan Mullan, a graduate student in the astronomy department who is helping to organize the event. "The colors of individual lines and their locations along the spectrum can tell you what element made the flash." Each of these colors is a form of energy that is created when electrons of atoms from particular elements -- such as the calcium or sodium from which many fireworks are made -- jump from positions of higher energy to positions of lower energy.

"These glasses are a fun way to show people how we know what faraway stars and galaxies are made of," said Chris Palma, Senior Lecturer in Astronomy & Astrophysics at Penn State. Volunteers will distribute the eyeglasses, made by American Paper Optics, from 4:00 p.m. to 8:30 p.m. on 4 July 2009 at the astronomy department's Founders' Mall table at the Bryce Jordan Center.
