The Long Island Museum

1200 Route 25A, Stony Brook, NY 11790 - United States




Smithsonian Affiliate Museum

The Long Island Museum is dedicated to inspiring people of all ages with an understanding and enjoyment of American art, history and carriages as expressed through the heritage of Long Island and its diverse communities.

The museum has been accredited by the American Alliance of Museums since 1973 for excellence in exhibitions, programs and collection care. In 2006 the museum joined a small group of institutions nationwide as a Smithsonian Affiliate.


The exhibition Atoms to Cosmos: The Story of Brookhaven National Laboratory will be on view in the Main Gallery of our History Museum from April 21, 2022 through October 16, 2022.

This ambitious exhibition organized in partnership with Brookhaven National Laboratory, will invite the Long Island community to explore the social, scientific and technological history of one of Long Island’s most important and internationally-influential modern institutions since 1947. From its 5,300-acre site in the Long Island Pine Barrens in Upton (just 18 miles away from this museum), Brookhaven National Laboratory has operated as a United States Department of Energy national laboratory at the forefront of crucial scientific research and development.

A total of seven Nobel prizes have been awarded for work conducted at BNL. As one of Suffolk County’s leading employers and a vital economic and cultural center with a long, complex, often misunderstood, and sometimes controversial past, BNL’s story will have enormous audience appeal. A closing substantial section/chapter of the exhibition will explore how science currently being explored at BNL will have significant implications for the world in the future. In partnership with the lab, LIM will tell the important BNL story to our museum visitors through a combination of artifacts, historic photographs, film, and interactive components.

Thank you to our generous sponsors and lenders.
