We want to thank Dan McCormick, Alan Daroff, Dr. Ken Kremer, Ted Williams and Mike Mountjoy for an enjoyable evening out at the Franklin. Dan gave us a great introduction to signing onto our Network site and a short review of RSS feeds. Alan kept us up on what is happening above, and Ken focused us in on all the activity we are conducting on Mars. Ted helped us to find our proper location in the visible Universe with a self address stamped "Intergalactic Mailing" commemorative for International Year of Astronomy 2009.
Mike topped off the evening with
an awesome presentation about the Franklin memorial renovation. The
presentation utilized 4 high end video projectors coordinated to an
amazing DMX computer controlled lighting system complete with LED color
washes and automated "smart" lighting similar to concert lighting systems utilized
today with some of the larger events. What attracted many questions was
the tablet PC control board allowing the operator amazing control over
the system at the touch of a portable hand held screen. Ben Franklin
looked truly amazed and gratified sitting amidst the effects of modern
technology.
Thanks to all who put forth the effort to present and provide an amazing evening at the Franklin. |

David J. Thompson ~ NASA Goddard Space Flight Center "Fermi / GLAST: Viewing the Extreme Universe" |
||||||||||
The
Fermi Gamma-ray Space Telescope, formerly called GLAST, is a mission
to study the most energetic form of light: gamma rays. In addition
to breakthrough capabilities in energy coverage and localization,
the very large field of view enables observations of 20% of the sky
at any instant and the entire sky on a timescale of a few hours.
Following its launch on 11 June 2008, Fermi now opens a new and
important window on a wide variety of phenomena, including pulsars,
black holes and active galactic nuclei, gamma-ray bursts, the origin
of cosmic rays and supernova remnants, and searches for hypothetical
new phenomena such as supersymmetric dark matter annihilation.
Dr. Thompson presented ground breaking and brand new discoveries just
announced this week at the annual AAS meeting: The discovery of 12 new
gamma-ray-only pulsars and detection of gamma-ray pulses from 18 others. The
finds are transforming our understanding of how these stellar cinders work.

Thousands of spacecraft have been launched since the beginning of the
space age, from Earth-orbiting satellites to missions exploring the
solar system and outer planets. Complex techniques are used to navigate
spacecraft into the orbits and trajectories required to reach mission
objectives.
In this talk, we learned how spacecraft are accurately navigated as
they orbit the Earth, land on other planets, and travel across the solar
system. The talk included the results of historical research and
visualization techniques that will appear in the Smithsonian Historical
Atlas of Spaceflight, to be published in 2009. |

Meeting Night
10/8/08 ~~~~~~~~~~~~~~~~~~~~~~~ Members night is a special occasion. Listening to fellow members, and learning a bit about our organization and who we are is special in itself. We started off the evening with proposals for our membership to consider as we line up our agenda for the International Year of Astronomy-2009. Ted Williams outlined the ideas in our September newsletter. We reviewed the goals and objectives of IYA, and explained our 3 proposals which include the Heritage Project, the Ritten Ledger, and our focus on native mythology and related cosmology. We showed the Ledger and shared some ideas of how we might use it to track and get feedback from members and visitors throughout IYA 2009.Alan Daroff reviewed what’s up in the night sky for us including the two stars (Epsilon Aurigae and Delta Cephei) that Ivin Williams has written on in the past two newsletters. Members were able to locate them amidst the Fels planetarium sky along with finding Jupiter. Ivin Williams introduced himself to our membership, and enticed us with some of his Navajo background, including how his people were solidly grounded in their environment. He pointed out that to know the Navajo people, one needs to know the land, the topography, the climate, and how it helped to shape their lives. Ivin previewed what he would like to focus on during IYA. Ruth List informed us about the Heritage project and her progress in the electronic publishing of the original Rittenhouse book coving our history from 1888-1960. It has some great articles including the History of Astronomy in America, along with the history of local observatories that used to send representatives to RAS meetings to share their findings. We were amazed at how RAS helped to save the Naval Academy Observatory at a time when it was relied on for accurate timing for trains, including those passing through Penn Station in Philadelphia.Dan Benedict served up and navigated an amazing planetarium display as we traveled around the globe to observe the daily motion of the stars from various locations on Earth. We appreciate the extra work for the programming involved to make this presentation happen. Dave Walker did an excellent historical perspective of rockets that were developed to boost us into space. He highlighted some of the spacecraft that have topped those rockets. His talk spanned Sputnik the latest rockets from nations around the world. Clouds were obscuring the view at this point in our evening so we closed out the meeting with some holiday gift ideas. A few recommendations of why binoculars are better for young observers and a few home planetarium models were reviewed. I think we were all amazed with the Homestar Planetarium and its projection on the front of the Fels dome. We could pick out constellations along the Milky Way. |

Meeting Night
9/10/08 ~~~~~~~~~~~~~~~~~~~~~~~ Don Knapp (Planetarium Director of the Centennial School District) opened our minds and our eyes to the energy of light. What is light? What properties does light have? A discussion with demonstrations of Reflection, Opaque, Transparent, Lenses, Focal length, along with a demonstration of the combination of various frequencies of light (color) were presented as an opening to our new academic year. Don's talk was an excellent student lesson to lead into Tim Kent's presentation on astrophotography. Tim Kent helped us developed an understanding of what it is like starting out in Astrophotography. His frank discussion of what to enjoy and what to avoid along with the many examples of what one can achieve with some simple equipment were the focus of his presentation. Mr. Kent's recent book, "StarQuest, A Beginner's Guide to Digital Astrophotography " will be a valuable money saving guide to what you can expect to achieve when starting out at home.
The examples of his work on display were quite motivational, in effect showing what a beginner can accomplish. His work shows much professional quality, and we even found the Friedman spot on one of Tim's moon photos. Quite a nice evening for all who attended. |

Gustav Holst was a British composer who was born in Cheltenham England in 1874 and died in London in 1934. One of the last great pieces of music he composed “The Planets” is an overture to the Planetary Celestial Spheres of our Solar System. Before the time of Space probes, Holst composed 7 musical suites each founded in the mythical characteristics and physical appearances provided by telescopes of the visible planets of his age. Now that Pluto has been re-classified and is no longer considered a planet, the music of Holst can once again represent the solar system of today.
