Live Public Programs at our
facility
are held every Saturday April through October 2026
Founded in 1988, United Astronomy Clubs of New Jersey, Inc. (UACNJ) brings together a dozen amateur astronomy clubs from across New Jersey, New York, and Pennsylvania. We're not a club ourselves, but a consortium: a shared voice and resource for the thousands of people who share a passion for the night sky across the tri-state area.
One of our biggest roles is getting astronomy out into the community. You'll find us at major events across the region, including Rockland Astronomy Club's North East Astronomy Forum (NEAF) every spring. And since 1994, we've been welcoming the public to our observatory in Jenny Jump State Forest every Saturday from April through October, completely free of charge.
UACNJ is an all-volunteer nonprofit 501(C)(3) organization, and every dollar we receive goes directly toward keeping our programs free and our facilities running. If you'd like to help, we'd love to have your support. You can donate online using the links in the sidebar, or send a check made out to UACNJ to P.O. Box 251, Hope, NJ 07844. If your employer offers matching gifts, that's a great way to double your impact. A receipt for tax purposes is available upon request.
UACNJ Observatory at Jenny Jump
Our observatory sits at 1,100 feet above sea level deep within Jenny Jump State Forest, near Hope in Warren County (Latitude 40 54' 26.8" N, Longitude 74 55' 31.8" W). It's one of the last truly dark sky sites in New Jersey, and home to several permanently mounted telescopes ranging from a 7-inch APO refractor to a 16-inch Schmidt-Cassegrain.
Jenny Jump is a great destination beyond astronomy too. The forest offers camping and hiking for all skill levels. Skylands Visitor is a great resource for exploring nearby attractions in the region.
