Los Alamos National Laboratory (Bradbury Science Museum)

The public museum of Los Alamos National Laboratory sits at the end of a story that began in 1943, when the U.S. government built a secret facility on a New Mexico mesa to design and assemble the first atomic bombs — weapons used at Hiroshima and Nagasaki in August 1945. The laboratory that grew from that project now conducts research across national security, nuclear science, and medicine. The museum is where that history faces the public, and it doesn't flinch.
