This Halloween there will be a blue moon'€”the second full moon this month! Although you might think of a full moon when you think of Halloween, it doesn'€™t always happen this way. Are there astronomical happenings that always do happen on Halloween? Join them and find out! They'€™ll be using a planetarium simulator to view the night sky. Just like programs in the Planetarium, they'€™ll be able to take questions'€”this time through chat and comments. Recommended for ages 6'€“10. Registration required
