Kopernik Observatory & Science Center
Kopernik Observatory & Science Center (KOSC) is a public science and astronomy center in Vestal, New York. Opened on June 16, 1974, it was created by the Kopernik Society of Broome County to honor the 500th anniversary of Nicolaus Copernicus. The center aims to give people of all ages hands-on opportunities to explore astronomy and science using advanced telescopes, computers, and other tools. It was the first science laboratory facility in New York State designed for K–12 teachers, students, and their families, and has been a well-regarded public observatory in the Northeast for decades.
History
- Original construction: In 1973–1974, Kopernik Observatory was built with two telescope domes. It opened to the public in June 1974 and was then operated as Roberson-Kopernik Observatory by the Roberson Museum and Science Center as part of its educational efforts.
- Major expansion: With support from the Kopernik Society and others, Roberson expanded the facility in 1992–1993, creating the Kopernik Space Education Center (about 8,000 square feet). The addition added a third telescope room, four classrooms, a space science theater, and laboratories for laser physics and computer imaging.
- Financial challenges and restoration of control: Around 2005–2006, the center faced financial losses. In 2007 Kopernik took back ownership and control from Roberson and renamed the site Kopernik Observatory and Science Education Center, aiming to raise about $54,000 per year in grants and donations to operate. By 2011, Kopernik had balanced its budget and continued independently.
- Independent operation: The center later became known as Kopernik Observatory & Science Center. It celebrated its 40th anniversary in 2014 with a gala featuring former NASA astronaut Douglas H. Wheelock as keynote speaker.
Programs and services
- Mission: To offer hands-on investigations and outreach programs that educate people about astronomy and science, using modern telescopes, computers, and other tools. It remains the first New York State science facility designed for K–12 teachers, students, and families, and a well-regarded public observatory in the Northeast.
- Association and access: Kopernik is a member of the Association of Science-Technology Centers and participates in the ASTC Passport Program, which allows members to visit other participating museums for free when traveling more than 90 miles from home.
- Public programs: The Observatory hosts weekly public programs on Friday evenings. Start times vary by season, with topics covering optical and radio astronomy, technology, and related subjects. There are also numerous special events throughout the year.
- Winter Star Party (since 2006): A night of astronomy with speakers and viewing opportunities, usually the last Saturday in January.
- RocketFest (since 2008): Rocket-building workshops throughout the day, with options for different types of rockets and engines.
- AstroFest (since 1982): A three-day celebration of the night sky with speakers, demonstrations, discussions, and observing if skies are clear; overnight camping is sometimes available.
- Moonlight Café: On selected Saturday evenings in spring and fall, the main building hosts adults-only evenings with coffee, desserts, and an introduction to the stars. Registration is through SUNY Broome Continuing Education.
- School programs: KOSC offers in-school and on-site STEM programs aligned with New York and Pennsylvania standards. Programs bring science and engineering topics to students and teachers and can be customized for different grade levels.
- Summer camps and day programs: Since 1992, the Kopernik team has run Link Summer STEM Exploration Camps for grades 1–12. Camps can be based at Binghamton University with various housing options. After the July 4 weekend, the center runs week-long summer camps and day camps with ongoing opportunities to learn about science, technology, engineering, and math.
- Summer science day programs include: Young Scientists (grades 1–2), Junior Astronomers (3–4), Earth Science (5–6), Young Engineers (2–3), Junior Engineers (4–5), and Master Engineers (5–6).
- Facilities and equipment: Kopernik is known for its strong telescope program and other facilities.
- Optical telescopes:
- E. Jay Sarton Telescope: 6-inch refractor in the eastern equatorial room, dedicated to former director E. Jay Sarton.
- Broome County Telescope: 14-inch Schmidt–Cassegrain reflector in the western equatorial room.
- Kopernik Astronomical Society (KAS) Telescope: 20-inch Ritchey–Chrétien reflector in the southern equatorial room, donated by the Kopernik Astronomical Society; one of the largest publicly usable telescopes in New York.
- Robert "Barlow Bob" Godfrey Solar Telescope: A 4-inch heliostat reflecting sunlight into a 7-inch image on a classroom wall; dedicated in 2014.
- Other telescopes: Four 8-inch Orion Newtonians, one 10-inch Meade Newtonian, and multiple smaller scopes; a SBIG STL-1301E CCD camera is available for astronomy imaging.
- Amateur radio station: The center runs a permanent amateur radio station using the call sign K2ZRO, often open during public programs. The station has historical ties to Sputnik and amateur radio satellites.
- Location and climate: The observatory sits on a hill about 1,740 feet high in Vestal, on the western rim of the Choconut Creek area near the New York–Pennsylvania border. The region has a humid continental climate with cold winters and warm summers, and it is one of the cloudier and rainier areas in the country, which influences observing conditions.
