Today’s the Summer Solstice! Renae Kerrigan, the Curator of Science and Planetarium Director of the Peoria Riverfront Museum Dome Planetarium, joins The Greg and Dan Show for a conversation on what is popularly described as the “longest day of the year.”

Kerrigan discusses how and why the solstice occurs, the history of the solstice, and why the sun rises in different directions throughout the year.
