Stargazing at New Jersey Planetariums and Observatories

Four hundred years ago, the Italian astronomer, mathematician, and physicist Galileo first used a simple telescope to study the skies. In 2009, we celebrated the International Year of Astronomy to commemorate that important anniversary of scientific history.

While the Hayden Planetarium at the American Museum of Natural History in New York City is always a superb option in your personal quest to reach for the skies, New Jersey also has some top-notch planetariums and observatories of its own.

The Dreyfuss Planetarium was built in 1953 and was the first of its kind in the state. Since then, approximately 1.5 million people have visited its 50-seat star theater, which boasts a Zeiss ZKP3 star projector, capable of projecting up to 7,000 stars.

The Planetarium at Raritan Valley Community College in North Branch uses new digital equipment to take visitors beyond the more traditional, earthbound view.

Another facility offering cutting-edge technology is the Planetarium at the New Jersey State Museum in Trenton. The 150-seat facility with reclining seats features a Full Dome Video with the visual ability to soar into space to view other planets and Earth itself.

In addition, amateur astronomy clubs at facilities such as the Sperry Observatory at Union County College and the Robert A. Schommer Astronomical Observatory at Rutgers offer their time and telescopes to the general public, taking visitors on tours of the nighttime sky.
