About the Planetarium


Since 1973, the Longo Planetarium has been bringing stars to Northern New Jersey. Here you can explore the Universe from the Earth and other planets in our Solar System to stars galaxies and beyond. Our Digistar projection system can display thousands of stars, the planets and the Moon onto a 33-foot diameter dome. All are welcome to attend public programs; school, camp and scout groups can be scheduled in advance. Our spring schedule features the following public programs on the 2nd and 4th weekends of the month.


Tickets for all shows are $10 per person. Online reservations are strongly encouraged; limited tickets will be available for purchase at the door. Please note the ticket purchases cannot be refunded or exchanged.

All programs start promptly at the times indicated. For your safety, guests will not be admitted or readmitted to the Planetarium theater once the lights are off, so make sure to arrive early and plan for any unexpected delays in travel and parking!

Tickets cannot be refunded or exchanged. See Public Shows for a list of current programs and to purchase tickets.
