One of the most popular shows at the David M. Brown Planetarium, Season of Light is an annual holiday program about the coldest and darkest of seasons - a time which holds some of the warmest and brightest celebrations of the year. This multicultural presentation traces the history and development of many of the world's most endearing holiday customs, all of which involve lighting up the winter season. Audiences learn about a few northern hemisphere winter constellations, discover why we have seasons, observe the Sun's path across the sky throughout the year, and see the Earth's tilt and orbit around the Sun.
