4 Places to Stargaze on the Main Line

Get a glimpse of some astronomical wonders this summer.


Whether looking to spend a romantic night stargazing or just wanting to take a peek at these marvels, there are quite a few places on the Main Line to do so. Keep in mind: Conditions for the best stargazing can be achieved only when the night is dark and dry, the sky is clear, there is no haze and very little pollution. Delaware, Chester and Montgomery counties are known to be home to many beautiful open fields. The key for any interested stargazer is the higher the spot, the better. 

These four spots fit the bill: 

Bradstreet Observatory
Built in 1996, Bradstreet Observatory is owned and operated by Eastern University. The public has been visiting the observatory on Tuesday evenings for the past 20 years. If interested in seeing celestial objects illuminating the night skies, sign up early, as most sessions fill to capacity.

Upcoming Astronomical Events:

June 24: New Moon 
The moon will be located on the same side of the earth as the sun and will not be visible in the night sky. This is the best time of month to observe faint objects such as galaxies and star clusters.

July 9: Full Moon 
Those looking to observe the craters of our moon will have the best chance when it’s fully visible in the night sky.

July 29 – 30: Delta Aquarids Meteor Shower
The Delta Aquarids is a shower that can produce up to 20 meteors per hour at its peak. The shower runs annually from July 12 to August 23 and will peaks this year on the night of July 29 and morning of July 30. The crescent moon will set by midnight, leaving dark skies for what should be a good early morning show. Best viewing will be from a dark location after midnight.

August 11 – 12: Perseids Meteor Shower  
The Perseids is one of the best meteor showers to observe, producing up to 60 meteors per hour at its peak. Best viewing will be from a dark location after midnight.

August 21: Total Solar Eclipse
A total solar eclipse occurs when the moon completely blocks the Sun, revealing the Sun’s outer atmosphere. This is a rare event for viewers in the United States. The last total solar eclipse visible in the continental U.S. occurred in 1979 and the next one will not take place until 2024. 

September 5: Neptune at Opposition
The blue giant will be at its closest approach to earth and its face will be fully illuminated by the sun. It will be brighter than any other time of the year and will be visible throughout the night, appearing as a small blue dot in all but the most powerful telescopes. 

Our Best of the Main Line & Western Suburbs Party is July 25!
