Christopher Nolan's film Oppenheimer has renewed interest in that Cold War era of Las Vegas, when visitors could occasionally see a roiling mushroom cloud in the distance at the nearby Nevada Test Site. Located on the corner of the UNLV campus and operated in association with the Smithsonian, the museum is filled with film footage and artifacts from the Test Site, including bomb-testing machinery and the bombs themselves: a decommissioned B-53 "bunker buster" is 12-feet long and weighs 8,850 pounds. Some exhibits are pay homage to the sometimes frightening, sometimes comical treatment of "the bomb" in pop culture. There's a mini-theater that gives you the sensory jolt of an atomic explosion. Two galleries for rotating exhibits augment the permanent exhibition. Early 2025 brought the new "Atomic Odyssey" exhibit, a colorful, interactive, and kid-friendly introduction to the structure of the atom and how to tell nuclear fission from fusion.
The museum also offers virtual tours of the 1,375-square-mile Nevada National Security Site (larger than the state of Rhode Island) and is the starting point for occasional in-person group tours of the test site, which is still operational 65 miles northwest of Downtown. These tours book as much as a year ahead, with museum donors getting first chance.
