July 12 – August 2, 2015

For several weeks each summer, Brookhaven Lab welcomes members of the public to its site. We plan days that include visits to our facilities, opportunities to speak with our researchers, special activities for adults and children, and much more—and it’s all free!



Exploring the Ultra Small

Visit the Center for Functional Nanomaterials, where Brookhaven researchers probe structures as tiny as a billionth of a meter. Learn about scientists’ latest discoveries in innovative energy technologies. Be amazed by “Atoms, Molecules, Matter and More!”



Brilliant Light, Dazzling Discoveries

Tour the National Synchrotron Light Source II, the world’s brightest synchrotron light source! Learn how scientists will illuminate the inner workings of batteries and seek answers to some of the nation’s toughest energy challenges. Be enlightened by the “Science Laser Light Spectacular.”



Family Fun Day

A fabulous day of hands-on family fun! Use the basic scientific method to explore magnets, mirrors, and more! Hop aboard a fire truck and learn all about the Laboratory’s protective services. Be mystified by the “The Mystery & History of Magic.”



Atom-Smashing Fun*

Visit the Relativistic Heavy Ion Collider, a world-class particle accelerator where physicists recreate the conditions of the universe as they believe it existed microseconds after the Big Bang! Stump a physicist and meet “Einstein” alive.

* Facility tour appropriate for ages 10 and over.
