Construction Update (Photo Gallery Below):
Construction has begun to repair damage caused by the January 2023 roof fire. 
We are planning to resume in-person shows this fall.
In the meantime, keep up-to-date with events on our Facebook Page.

To our teachers, educators, parents and grandparents and education friends:
Until we can host school tours again, please visit the FOR TEACHERS page for educational materials. 
Our YouTube Page also has videos of our live shows and presentations!


The Ward Beecher Planetarium, located on the Youngstown State University (YSU) campus, serves as an astronomy and science education resource center for the Mahoning Valley and surrounding communities. A YSU facility in the Department of Physics, Astronomy, Geology, and Environmental Sciences (PAGES), we support astronomy teaching on campus and provide a variety of educational programs to public and private groups of all ages. 


In the rows labeled "sky conditions", find a column of blue blocks. You can probably observe then.

Read the image from left to right. Each column represents a different hour. The colors of the blocks are the colors from CMC's forecast maps for that hour. The two numbers at the top of a column is the time. A digit 1 on top of a 3 means 13:00 or 1pm. It's local time, in 24hr format. (Local time for Youngstown is -4.0 hours from GMT.)
