COVID-19 Update

Out of an abundance of caution related to the spread of the COVID-19 virus, Brookhaven National Laboratory is suspending all public tours and visits until further notice. Updates will be posted here. Thank you for your understanding.

Meet the people who make the leading-edge research at Brookhaven National Laboratory happen. Learn about our science. Visit our world-class tools of discovery.

We look forward to hosting group visits in the future. Until then, we invite you to watch these guided virtual tours of some of our big facilities.
