The Kopernik Observatory & Science Center (KOSC), is a public observatory in Vestal, New York opened to the public on 16 June 1974 by the Kopernik Society of Broome County to commemorate the 500th anniversary of the birth of the astronomer Nicolaus Copernicus () in 1973. Its mission is to offer hands-on investigations and outreach programs for educating all ages about astronomy and science using advanced optical telescopes, computers and other tools. It is the first science laboratory facility in New York State designed for K-12 teachers, students and their families, and has been one of the best-sited and best equipped public observatories in the Northeast United States for nearly the last 40 years. History Original construction In 1973, the Kopernik Polish Cultural Society of Broome County organized in order to build a community observatory to commemorate the 500th anniversary of the birth of the astronomer Nicolaus Copernicus (). The Society's goal was for everyone in the region, regardless of ethnic background, to experience the universe firsthand at the new Kopernik Observatory. The Kopernik Society secured donations of materials, services and funds from the community and planned for construction to begin in the fall of 1973. General Contractor Edward Nezelek, Chairman of the Kopernik Observatory committee, completed the observatory in the spring of 1974. The facility, designed by James Kilcy, consisted of a astronomical observatory with two telescope domes. After the Observatory was opened to the public on 16 June 1974, the Kopernik Society donated the facility to the people of the Southern Tier region, to be operated by the Roberson Museum and Science Center as the Roberson-Kopernik Observatory, part of Roberson's educational initiative and to complement the major planetarium already in operation at its Binghamton site. Major expansion With major support from the Kopernik Society, the Decker Foundation, and many other community organizations, Roberson undertook a $2 million expansion of the Observatory to create the Kopernik Space Education Center in 1992. It would convert the Roberson-Kopernik Observatory into the first science laboratory facility in New York State designed for K-12 teachers, students and their families. The envisioned expansion would add a third equatorial room with a large telescopes, four classrooms, a space science theater, and laser physics and computer-imaging laboratories. Construction of the Center began in the Fall of 1992, Kenneth R. Gay II was the Architect, and the facility addition opened in June 1993. The Kopernik Society and
