Outreach & Education


One of the purposes of the AAAP is to educate the public about the wonders of the universe over our heads through our lecture series and outreach program.

Our astronomers setup telescopes for public use at Communiversity in Princeton, Super Science Saturday at the NJ State Museum in Trenton and at various public events around Mercer County.

We will bring telescopes to your school or educational event to show and explain objects in the night sky like the Moon, constellations, planets, nebulae and galaxies.


Sidereal Times


Sidereal Times is the official newsletter of AAAP since 1962.

Published in blog form now, it is the best source of current news about club activities. In addition, we publish essays, gear evaluations, astrophotographs, book and movie reviews, poetry, travelogues and technical articles related to our hobby.

AAAP plans to post on this website soon our archive of all issues going back to the club's founding. We hope to complete this project soon.
