BUY COMBO TICKETS & SAVE! Make it a day of discovery and buy combo tickets to Longway Planetarium which is right across the street from Sloan Museum of Discovery on E. Kearsley! Combo tickets may be purchased in person at either the Longway Planetarium or Sloan Museum guest services desks, or purchase in advance at www.SloanLongway.org/combo-tickets. Please plan mindfully, as ticket sales are final and non-refundable. For a current list of Planetarium shows, go to www.SloanLongway.org/Now-Showing.
