Public Viewing Nights

Astronomy Nights are held on the first and third Thursday of each month that the university is in session.  The program begins with an indoor public planetarium show at the John R. Kirk Planetarium Tickets are REQUIRED for the planetarium show.  There is a suggested ticket price of $5 per seat. Astronomy Night activities are appropriate for ages 10 and up. A second show will be offered if the first show reaches capacity. 

After the planetarium show, Smolen Observatory will be open for telescope viewing only if the sky is clear (tickets are not required at the Observatory). Call the Observatory at 845-257-1110 to hear a message indicating if the public viewing has been canceled due to cloudy weather. Visitors can participate in either the planetarium show, observatory telescope viewing, or both.

Tickets for Astronomy Night Planetarium shows become available one week prior to each show.

Astronomy Night telescope viewing begins shortly after sunset and therefore the start time changes according to the seasons. The current Astronomy Night schedule is as follows:
