ABOUT THE FESTIVAL
Los Alamos ScienceFest 2026: It's All Elemental!
Los Alamos ScienceFest, now in its 19th year, celebrates the history and science of Los Alamos through fun and engaging activities and events for people of all ages. Each year, thousands typically participate in Los Alamos ScienceFest week and Discovery Day. Returning this September 18-26th for its 19th year, Los Alamos ScienceFest will feature a dynamic line-up of activities for all ages, celebrating Science, Technology, Engineering, Art and Math (STEAM) topics under the theme, "It's All Elemental!" Join us for Discovery Day on Saturday, September 26th from 10 am-2 pm at Fuller Lodge & Lawn and other locations around downtown Los Alamos.
It is our mission to:
-
Celebrate the scientific heritage and excellence of our community by showcasing cultural activities for people of all ages
-
Connect with scientists and engineers and experience how science affects our everyday lives
-
Raise awareness of STEM education (and future science and technology)!
-
Enable enrichment through science and technology

This year, in addition to the Los Alamos ScienceFest, MainStreet is working closely with the Bradbury Science Museum to pilot a regional ScienceFest effort with the goal of demonstrating the need for a state-wide science festival.
The Fall Festival at Los Luceros will serve as a kick-off event for this effort and more information will be coming soon.
The premier event, Discovery Day brings family fun to downtown Los Alamos, where attendees can visit tents with non-stop interactive science demonstrations, a children's activity area, music, food, beverages, and live musical performances.
Discovery Day will be centered around the historic Fuller Lodge and Lawn and additional sites and events taking place at Mesa Public Library, SALA Event Center, and Pajarito Environmental Education Center.
Similar to Discovery Day, Discovery After Dark focuses on interactive activities for adults! Bring on the risky and the NSFW science. (You cannot mess with these mini particle accelerators at work unless you're a physicist!)
MainStreet collaborates with local institutions like SALA Event Center, Bathtub Row Brewery, Samizdat Bookstore, Bradbury Science Museu and others to bring you playful STEAM activities for adults to unwind, learn and play! This is the 4th annual "STEAM for Adults" event.
