Why wait? Save time and avoid lines with advance tickets.

One of the most provocative symbols of the 20th century—the Doomsday Clock—inspires an exhibit illustrating why it matters as much today as it ever has in its 70-year history.

Recently set at just two minutes to midnight, the Doomsday Clock reflects the urgency of two major challenges confronting our world: nuclear weapons and climate change. Turn Back the Clock calls upon all of us—scientists, policy makers and ordinary citizens—to take part in the dialogue and debate about the important science and technology issues that have great impact on our lives.

Included in Museum Entry. Open through June 9, 2019.

Virtual Tour

The exhibit has left MSI, but Turn Back the Clock is now available in a virtual tour for visitors worldwide to explore online.
