314 Day Illumination on the McDonnell Planetarium

The exterior of the iconic James S. McDonnell Planetarium (part of the Saint Louis Science Center in Forest Park) will be illuminated with a NEW colorful, limited-edition 314 Day 2026 design, created by local artist Natashna Anderson (Instagram: @natash.naa).
Friday and Saturday (March 13-14) from 7:00-10:30pm each evening (weather-pending).
The light display will be visible from east- and west-bound Highway 40/64 or by visiting Forest Park and heading up Faulkner Dr. and around the Planetarium grounds (on the southwest side of the building).
