    Walk through our interactive exhibits to learn about the Manhattan Project, the Lab’s work on national nuclear defense, and the Lab’s research in life sciences, material sciences, space, supercomputing, energy, and the environment.

    History Exhibits

    • WWII and the Manhattan Project

      The in-depth timeline shows WWII events, along with Manhattan Project work and accomplishments. Each description is enriched with artifacts, videos, a guide to historic properties at the Lab, and badge photos of Los Alamos Laboratory luminaries. Browse the museum’s online collections of Manhattan Project artifacts.

    • A New Look at Trinitite

      Learn how this man-made mineral was formed by the Trinity Test. The exhibit features samples of Trinitite, the animals that helped to discover Trinitite’s origin (clue: they are nature’s “miners”), and a sample from Semipalatinsk, Kazakhstan, where the Soviet Union tested their version of the Gadget.

    Photographs and bios of people you may have not heard of, created by photographer AJ Melnick. These are the Everyman and Everywoman who made Project Y a success.

    Defense Exhibits

    • Mission: Nuclear Deterrence

      The Lab’s central mission is to enable the U.S. to have a safe, secure, and effective nuclear deterrent. Learn about this mission, what a nuclear weapon is, how weapons are fielded by the nuclear triad, and what and where the Nuclear Security Enterprise performs Stockpile Stewardship. This exhibit is highly interactive! View a simulation of the Cuban Missile Crisis. Can you make the best choices throughout the crisis to avoid nuclear war?

    • 50 Years of Nuclear Safeguards

      For over 50 years, the Lab has been enabling nuclear safeguards around the world. Learn about the technology the Lab invented to surveil nuclear materials and how the International Atomic Energy Agency inspectors do their work to promote global security.

    • Nuclear Explosion Monitoring

      “Trust but verify” means we stay vigilant and observe nuclear explosions around the world. The earth literally “rings” like a bell when an explosion occurs, and this exhibit on Nuclear Explosion Monitoring explains what happens and how we sense it. Sit in the Seismic Seat to feel how earthquakes, chemical explosions, and nuclear explosions propagate through the earth.

    The Science of High Explosives image

    The Science of High Explosives

    High explosives are necessary for nuclear weapons to work. Explore how Lab scientists perfect better, less sensitive explosives.

    Radioactive Source Recovery image

    Radioactive Source Recovery

    There are many uses for nuclear materials. When they have finished their service to industry or medicine, what happens then? The Lab has a program for that!

    Underground Nuclear Tests in Nevada image

    Underground Nuclear Tests in Nevada

    Before Stockpile Stewardship the U.S. performed almost 1,000 nuclear tests. Explore this work and history.

    Research Exhibits

    • Supercomputing

      Supercomputing has evolved hand-in-hand with the US nuclear deterrent. See the evolution of this technology from Manhattan Project days up to today. Women have been an integral part of this history; explore the timeline of their work and accomplishments.

    • Nanotechnology

      The Lab’s Center for Integrated Nanotechnology explores what kind of work can be done at the nano level, where atoms interact with other atoms. View the techniques for doing this work that explores how materials are actually made atom by atom.

    • Building Immunity

      Biosecurity research–to understand immunity, disease spread, and the evolution of viruses like influenza and HIV–is also part of the Lab’s work. Explore what the Lab does in this area, enabled by our supercomputing capabilities.

    • Environmental Research & Monitoring

      The Lab campus occupies 40 square miles and shares this space with over 2,000 archaeological sites, historic properties, threatened and endangered species, and a natural environment that must be protected. See what’s at the Lab and how we embrace environmental compliance fully while accomplishing our global security goals.

      Enviro Research

    • Understanding Radiation

      Fundamental to the Lab is working with radioactive materials and leveraging their decay. How does decay happen, what kinds of radiation are there, how do we use radiation in common technologies, and what kinds of radiation do we all experience? Find the answers in this exhibit.
