Syracuse Astronomical Society President’s Message for March, 2007

In the interest of keeping track (yet again) of where anything I commit to the web goes and what good it may be, I’m reposting my monthly messages to the Syracuse Astronomical Society (SAS) here. If, by chance, you find me first, are local (Syracuse), and have any interest in SAS activities, do drop a line. We’d love to see your featureless outline at our observatory this year.

President’s Message for March, 2007

This Month’s Newsletter…

Stu Forster has outdone himself this month with the March Newsletter. I will not go into detail here, but highly recommend the preparatory material for the Marathon this weekend and the extended discussion from Jordan Blessing of Scopetronix.

2007 Messier Marathon

It is that time of year again! The SAS is having its annual Messier Marathon this coming weekend (March 16th/17th). I will not expound on the man (Charles Messier) or the mission (The Marathon) here, instead directing you to a few thorough websites on each. Between mid-March and early April, it is possible to observe all 110 objects in a single night. This, of course, requires the use of a number of “IFs” (IF the sky’s clear, IF the moon’s new, IF you’re far enough from very bright light sources, IF the grease in your focus knob doesn’t turn to stone in the freezing conditions, etc.). As has been usual, the Marathon will be held at “little Eridanus,” otherwise known as Stu Forster’s driveway. Friday the 16th is the expected night for it, with Saturday the 17th being the weather alternate (be sure to check the website Friday afternoon to confirm the date). For directions to Stu’s house, email him at SHFORSTER1@aol.com.

As an aside, I was, at first, surprised to discover that critics of the Marathon exist, complaining that this “race to the finish” doesn’t allow people to enjoy the beauty of the Messier objects. Well, I said there are critics; I did not say they had deep philosophical arguments with it. Everyone’s a critic, I suppose. Sunday drives down 81 South to the observatory are always relaxing in the Fall, but many more people are at home watching NASCAR, somehow symbolic of the high-speed nature of our society. If nothing else, the Messier Marathon gives everyone their first orchestrated “dusting off” of their knowledge of the night sky before the seasons change and the nights become comfortable enough to enjoy being out in.

But wait! There’s more! We are currently being graced by the presences of Venus (the bright object to our West and, of course, the third brightest object in our sky) and Saturn (to our East, in the vicinity of Leo and Cancer for most of the night). Venus will disappear quickly on the nights of the 16th and 17th (around 8 pm, but visible early in the pre-night sky), while Saturn will come within 20 degrees of our zenith by midnight.

Prof. James Cordes MOST Space Series Recap

Those of us at the MOST on March 8th were treated to an excellent lecture by Prof. James Cordes of Cornell University. The title itself, “Radio Telescopes And The Search For Life In The Universe,” may have done more to bring out the Syracuse X-Filers than the amateur astronomy community, but the search for life does not just entail listening for celestial Morse Code. Radio astronomy enables us to study the entire universe as well as our nearest neighbors (see the radio imaging of Jupiter and the Sun below), through which we can come up with models of universe age, formation and layout. From that, we can begin to consider how the universe may or may not be hospitable to one, few, or many forms of life and, perhaps, where best to look. It is from our understanding of the existence of life in the universe and what we assume to be the requirements for life on other planets (water, heat, raw materials), that we even have the notion of a “Habitable Zone” that drives astrobiology research.

The progression of the field (proof our tax dollars do go to some good) is best summarized in the two images below. The first, from a 1924 issue of the magazine “Radio Age,” shows Corp. John H. Sadler “listening in” to radio signals from Mars, no doubt hoping to intercept the sounds of the Martians so that Orson Welles‘ prop manager would only have to make one trip to the Acme Sound Effects Store. A mere 83 years later, Dr. Cordes spent the end of his talk presenting the S.K.A. (Square Kilometer Array, not that hip sound from way out the kids dig in Central New York), a massive radio telescope facility that will, among other things, explore fundamental questions about the “origin and evolution of the universe.


A collaborator of Dr. Cordes that did NOT go unnoticed is astrophysicist Dr. Volker Springel at the Max-Planck-Institute for Astrophysics in Germany. His work in simulating galaxy formation and the evolution of the universe makes for some incredible animations (and many publications). As an example, I direct you to the gallery of galaxy formation images and movies from the Millennium Simulation project.

Amassed Astronomy Media Part 1: Podcasts

In case you didn’t yet know (and who doesn’t?), there’s plenty of material available online to make you a better, more informed astronomer. In Syracuse, we often have to learn more from looking down at the screen than up with the scopes! In the interest of saving everyone google searches for the astronomical “best of the ‘net,” I’ve added a new astronomical media page to the website, at which the plan is to keep an accurate list of useful (and favorite) podcasts, image galleries, and general astronomical info. We welcome feedback and (more importantly) links to your favorites.

The list begins with podcasts, which have gone from obscurity to ubiquity over last few years. If you’re still unaware of what podcasts are, I direct you to one of several websites that explain the 5W-H’s. There are a number of phenomenal podcasts out there that deal with astronomy education and general stargazing. The media list begins with four of my favorites. I have made direct links to the podcast feeds on the list below that will subscribe you to these podcasts automatically in iTunes (which is freely available from Apple. Podcasts do NOT require iPods!).

1. Stardate [iTunes Podcast Link] – The best 2 minutes on radio. Until the show became available as a podcast, I would endeavor to make sure I was by a radio tuned to WRVO at either 6:58 am or 6:58 pm for my daily fix of Sandy Wood and the night’s festivities. If our own Mike Brady were to begin handing out seals of approval, I suspect Stardate would get the first.

2. Jack Horkheimer: Star Gazer [iTunes Podcast Link] – I suspect anyone that grew up watching WCNY knows the name Jack Horkheimer, whose Star Gazer program has run on Sunday evenings (around 6 pm) for as long as I can remember. Easily the most enthusiastic man in Astronomy with, very likely, the most easily understood descriptions you’ll find about the week’s best night views. Both audio and video podcasts are available, the video version being the same as seen on PBS stations.

3. Astronomy 161/162 [iTunes Podcast Links For 161 and 162]- Prof. Richard Pogge (pronounced Po-Gee) is a Professor of Astronomy at Ohio State. The Astronomy 161/162 podcasts are the audio from his classes, which cover general astronomy at an undergraduate level. These lectures are excellent material for reminding yourself of things you forgot (definitions, methodologies) and learning about much of the best history and basic science in astronomy (do you know why a “foot” is divided into 12 inches?). College level astronomy for the cost of a few megabytes on your hard drive. I don’t think there’s a better deal out there. If that weren’t enough, his department website includes all of the lecture notes from the class, so you don’t even have to go hunting for an H-R diagram. Also a Mike Brady favorite.

4. Astronomy a Go Go [iTunes Podcast Link] – This podcast appeared early in the history of the iTunes Music Store and has a good, long run to date. Show host Alice Few has been providing podcasts on most everything astronomical since late 2005. In addition to the regular shows, the podcast features a monthly “Tour of the Night Sky” where Alice walks you through what’s up there in a relaxed, easy to follow manner (plenty of time to convince yourself you’re seeing what you think you’re supposed to be seeing!). As if the podcast weren’t enough, the Astronomy a Go Go website is quite possibly the most content-rich site for amateur astronomy on the web.

This is the beginning of the list! The plan is to include many other links in the Astronomy Media page. If you have favorite links, please send them along and, if you like, include a description of why you like it.

NASA Night Sky Network


Click here to watch an introductory video.

Some of you may have noticed that we went national with the latest web update. The SAS joined the NASA Night Sky Network late last year. The NASA website describes the Night Sky Network as “a nationwide coalition of amateur astronomy clubs bringing the science, technology, and inspiration of NASA’s missions to the general public.” This Network was put together by NASA, the Astronomical Society of the Pacific, and the Astronomical League, and is kept going with the help of the many (many) societies across the US, including our selves and our friends to the East, the Mohawk Valley Astronomical Society in Clinton.

It is an excellent arrangement for ANY astronomical society. NASA provides materials, connections, and a base of operations at the NSN website for helping people find local astronomy clubs. We continue to do what we try to do best: get people to look up! One of the active membership benefits is the arrival of Toolkits, self-contained projects including videos, documentation, and demonstration materials. The purpose of these Toolkits is to present some topic with visual aids in detail. We currently have the “Shadows & Silhouettes: Phases, Eclipses, and Transits” Toolkit ready for presenting at the Darling Hill Observatory opening in April.

While the purpose of the Night Sky Network is public outreach, our activity as of late has hovered… somewhere below the tree line recently, a result of the down-time in activities for the SAS that comes with the winter months and life in Syracuse. The opening of the observatory in April and monthly Spring/Summer viewing will be serving as the bulk of our contributions to the Night Sky Network, with the specific activity roster for the year’s viewing in the works and the current schedule available on the Meetings and Public Viewing page. As always, we’d love to see your dark, featureless outline at our public viewing sessions.

As this post has gone a bit long, the review of the Celestia program will be spared for the next message, at which any update from the Messier Marathon and new additions to the media page will be posted.

Space is the place,
Damian Allis, Ph.D.
