Following are answers to questions we are asked the most:
Are you open?
Click HERE to see our 2018 Public Hours
Is there an admission fee or registration required?
No, however we are a non-profit volunteer run organization so donations are always appreciated.
What is there to do?
All visitors are treated to a guided tour of the facility, which includes our 26” Cassegrain Telescope – the largest public telescope in NJ. We also have many photos and exhibits on display, including a detailed scale model of New Horizons – the spacecraft that was the first to visit Pluto! Of course, we also have a store for young astronomers to pick up an item or book on space and astronomy!
On Saturday evenings, if sky conditions permit, we will explain the night sky and invite you to view through our telescopes where you can observe planets, galaxies, nebulae and star clusters. On Sundays we offer solar viewing. Sunspots and solar prominences may be visible, if the Sun is cooperating!
Camping, Hiking and Picnicking
We are located within Voorhees State Park, which offers camping, hiking and picnicking. See their website for information and reservations.
Is there a program tonight ?
Our Featured Astronomy Presentations are on the 4th Saturday of the month (March – October) at 8:30pm. However, it is always best to check our online Calendar and home page for details and announcements of special events.
Is there a special program for children ?
We offer 6 youth program events each year. These events are available to children ages 7 - 13. Seating is limited and sign-up required. See: Youth Education.
Where are you located ?
We are on Observatory Road in Voorhees State Park, Glen Gardner, NJ 08826.
If using a GPS device, search for "Observatory Rd" in all NJ cities and select the one in Glen Gardner. This road will take you right to the Observatory (top of the hill).
Additional road directions can be found here.
Should we come if the sky is overcast (cloudy) ?
If the sky is overcast, we will not be doing any telescope or visual observing at all. However, we will still offer tours of the Observatory, our Store will be open and we will be available for questions.
Can I bring a group ?
Groups of 10 or more must make a reservation request here at least one week in advance of visiting the observatory. Note: Scout and youth group tours are administered on calendar and NJAA resource availability.
When is the best time to visit ?
Anytime we are open and the sky is clear is a good time. If you can see stars in the sky from your home, then we should be able to see them too. However, the most ideal time is when the moon is not visible or in its crescent phase.
