Calling all early birds! If you want to catch the view of a planet this month...Venus is easier to spot due to its brilliance, particularly if you have a clear eastern horizon. Look for it about 30 minutes before sunrise for best viewing! #wherethestarshangout

Totality- Explore the Wonder of Eclipses
Do you remember where you were one year ago today?! It was the Great American Solar Eclipse! We had a beautiful day for viewing in Wisconsin and lots of people gathered here at the planetarium to celebrate. If you took any pictures, share them in the comments! Don't forget to mark your calendars for the next Total Solar Eclipse in Wisconsin...it will be on September 14th, 2099! 🤯 #wherethestarshangout
