[ Meeting Notice ]       [ Press Release ]

A new Quasar has erupted in a star system called Centennial School District  located in a constellation known as Warminster PA. 
Quasars are thought to be an immense outpouring of energy as a galaxy is formed.  It is a rare and special occurrence when one erupts so close that it is virtually in our back yard!.  Philip Vinogradov will be our guest presenter who will inform us about this special occurrence.



 Philip Vinogradov (Director of the 21st Century Learning Lab)  guides us through the universe (above) in the domed exhibition center.

Collaborating with students in one of the learning laboratories.

Just as a Quasar, Centennial School District has invested in what will be an amazing outpouring of learning energy powered by students in the district.   Please check out their "21st Century Learning Lab"  to get an overview of what the program is about.  The centerpiece of the facility is a domed exhibition area (which doubles as a Planetarium.)  Bravo Centennial School District!  The support of scientific excellence that the Centennial School District Community has invested in is to be commended!


Lovin' It !

For the Astronomy portion of our lesson:
Come hear some of the greatest love stories ever told.  Dave, Denise, Ted will be our storytellers as Dan plays live for our celestial soundscape.  Join us as we bring some mythological love stories inspired by the stars above to our members this Valentine's eve!

This year he included an amazing selection of video clips. We promised we would share these for members to "relive" the experience.  Guests, if you are not familiar with APOD, now is a good time.
 Thanks so much Robert!

Our past DECEMBER 12, 2012  Meeting
[ Meeting Notice ]       [ Press Release ]

Dr. Paul H. Halpern from University of the Sciences
has published "Edge of the Universe" (available this September.)  He joins us to talk about what we find at the edge, and what possibly lies beyond.  Cosmology, the science of the universe, is undergoing a startling revolution.

Colossal flows of galaxies, large empty regions called voids, and other unexplained phenomena offer clues that our own "bubble universe" could be part of a greater realm called the multiverse!

Voyage to Jamestown explores how sea navigation was accomplished during the era of discovery. Navigational methods and tools are presented within the setting of their use during a sea voyage of the period. While this voyage features a fictional crew and ship, it is carefully reconstructed from actual events, circumstances, narratives, and historical figures, which demonstrates the challenges of marine navigation within the cultural experience of people who actually traveled the oceans centuries ago.
