Virtual tour: Turn Back the Clock

Learn about the significance of the Doomsday Clock and how it has evolved to include risks we face today. Originally on display at Chicago's Museum of Science and Industry, the Turn Back the Clock exhibit is now available for visitors worldwide to explore online.

Through compelling personal stories, innovative interactive media, and pop culture artifacts, the exhibit takes guests through seven decades of history—from the dawn of the nuclear age to significant policy questions our leaders face today.

The virtual tour is best viewed on a desktop or tablet device. Tap on the interactive markers to focus on an artifact or panel, and tap again to enlarge those items further. To see a collection of the artifacts, click here.
