Great American Total Solar Eclipse

Prepare yourself for an astronomical event 575 years in the making. Visit the James S. McDonnell Planetarium and learn about the 2017 Great American Total Solar Eclipse occurring on August 21, 2017. Explore how the sun, Earth and moon behave to cause night and day, the seasons, and of course, how they can align just right to create an eclipse.

The Saint Louis Science Center and the James S. McDonnell Planetarium are providing learning opportunities leading up to and the day of the total solar eclipse that prepare and inform visitors about this exciting event. We will also have an Eclipse Festival on the day of the event as our Planetarium educators will narrate the events in the sky and provide fun activities for all ages. 

ONGOING PRESENTATIONS AND DEMONSTRATIONS

Explore how the sun, Earth and moon will align to create the total solar eclipse. Learn the best viewing locations and how to safely see the eclipse. Includes hands-on workshops with educators and eclipse glasses.

This demonstration provides visitors the explanation of why the moon goes through phases, and why we do not have an eclipse every month.

Safe solar observing demonstrations ensure that visitors know how to safely observe the sun with specialty eye instruments, and why it is unsafe to look at the sun without specialty eye instruments. Safe Solar Observing is experienced indoors, but also outdoors on every third Saturday of the month for Solar Saturdays.

Solar Telescopes and Sun Spotters will be located outside the James S. McDonnell Planetarium, and occasionally in GROW, on every third Saturday of the month for Solar Saturdays. The Solar Telescopes and Sun Spotters will also be available on select days (weather permitting). Call 314.289.4400 for more information.

Join us on the weekend of August 19 and 20 to hear from local astronomers and planetary scientists about why eclipses happen, how you can view them safely and what NASA and other space initiatives are studying.
