First Fridays at McDonnell Planetarium, weather permitting, the St Louis Astronomical Society and the Science Center will set up a number of telescopes outdoors and be on-hand to answer your questions.
The telescopes will be set up outside the McDonnell Planetarium Building entrance. Telescope viewing begins once it is dark and will end about 9 PM on the Planetarium grounds. Regardless of the weather, you can also join them indoors in the Planetarium Theater for “The Sky Tonight”. Showtimes are normally at 7 PM.
