Laboratory near Santa Fe, New Mexico

Los Alamos National Laboratory (often shortened as Los Alamos and LANL) is one of the sixteen research and development laboratories of the United States Department of Energy (DOE), located a short distance northwest of Santa Fe, New Mexico, in the American southwest. Best known for its central role in helping develop the first atomic bomb, LANL is one of the world's largest and most advanced scientific institutions. Los Alamos was established in 1943 as Project Y, a top-secret site for designing and assembling nuclear weapons under the Manhattan Project during World War II. This included both nuclear weapons used in the atomic bombings of Hiroshima and Nagasaki in August 1945, as well as Trinity, the first nuclear test, a month prior.
