“Upstate NY Stargazing” Series At newyorkupstate.com And syracuse.com – Summaries And Links For The Last Few Months

The old adage “if you want to really learn something, teach it” has been in full effect these past few months with the writing of the UNY Stargazing series for newyorkupstate.com and syracuse.com (which don’t combine the comments and shares. You have to go to both!). Firstly, it is excellent practice for anyone doing astronomy outreach to try to capture all of the events and observing opportunities that a new or casual observer might find interesting – while providing enough extra detail to whet the appetites of those reading with a wikipedia tab open (which remains the go-to for astro consistently accurate astronomy information). Secondly, if helps sharpen the editorial blade – such as by not using the word “old” to qualify “adage” when you’re really trying to keep it to 2500 words.

After 11 months of articles, the UNYStargazing template is fairly matured, Stellarium has moved well into advanced topics stage, and the many astronomy clubs that have allowed their public events to be posted have all resulted in an increasingly smooth and, hopefully, informative read.

Having ignored this blog generally recently, here’s the last four months in rapid succession:

– Upstate NY Stargazing in February: Lunar eclipse, Kopernik star party, ‘Dog Nights of Winter’

* nyup.com/outdoors/2017/02/upstate_ny_stargazing_in_feb…

* syr.com/outdoors/2017/02/upstate_ny_stargazing_in_feb…

Featuring a washed-out lunar eclipse and one of Larry Slosberg’s great lunar images.

– Upstate NY Stargazing In March: Messier Marathon and the Lunar Occultation of Aldebaran

* nyup.com/outdoors/2017/02/upstate_ny_stargazing_mar…

Friend and Kopernik Astronomical Society member George Normandin provided the eye candy to start the March article, which included a discussion of Messier Objects (such as M31, M32, and M110) still long enough to get the editor’s attention (but it was about Messier Objects and sometimes you have to say stuff). The Lunar occultation of Aldebaran was pointed out to the ASRAS email list by Brad Timerson and then promoted on the CNYO website.

– Upstate NY stargazing in April: Comet hunting and the Lyrid meteor shower

* nyup.com/outdoors/index.ssf/2017/03/upstate_ny_stargazing_in…

* syr.com/outdoors/index.ssf/2017/03/upstate_ny_stargazing_in…

Brad Loperfido of Revette Studio and the CNYO Facebook Group had an amazing capture of Comet 41P/Tuttle-Giacobini-Kresak, M97, and M108, allowing for a final addition to the Messier Object discussion with the objects that Messier was most interested in finding – comets. The month also included a washed-out Lyrid Meteor Shower peak and a proper shout-out to astronomy.fm.

– Upstate NY stargazing in May: A meteor shower and preparations for the solar eclipse

* nyup.com/outdoors/2017/05/upstate_ny_stargazing_in_may…

* syr.com/outdoors/2017/05/upstate_ny_stargazing_in_may…

The first in the series prepping for the great North American eclipse on August 21st of this year, featuring a NASA/SDO/AIA image (our tax dollars at work) and a continuation of the discussion of circumpolar constellations (which will get a full summary in four more articles).

Some Light Science Reading. The Constellations: Lyra

“The muse is upon me… bring me a small lyre!” – Caesar (via Dom DeLuise)

I have come to the conclusion that the constellation Lyra is my favorite, as it has all of the qualities one looks for in a celestial marker for a student of astronomy history, an amateur astronomer, and a part-time musician (well, drummer). Within its defined borders reside a famed double-double star system, a planetary nebula, a small globular cluster, at least one reasonable galaxy, one of the brightest stars in our night sky, a near-perfect parallelogram (if these were brighter stars, they would rival the Belt of Orion in geometric significance to terrestrial observers), one corner of the largest asterism in the night sky (the so-named Summer Triangle), and a host of other stars and dimmer objects (including even a few comets right now). This great variety of objects all lie in a small piece of property just off the band of the Milky Way and, during the summer, they are all ideally suited to near-zenith or at-zenith observing.

For our overture, we begin with the history of this mythic instrument. Lyra has most oft been associated with the famed musician of olde Orpheus, where Orpheus’ lyre was disposed of in a river not long after Orpheus himself was disposed of by maenads despite Orpheus giving the performance of his life (or for his life as the case may have been, as his playing reportedly kept rocks and sticks at distance, requiring the maenads to forego accouterments and pluck Orpheus apart with their own hands). Zeus, with his ever-present eye for collector’s items, ordered the lyre placed in the heavens along with the eagle that recovered it (and some old drawings of the constellation still include a bird of some kind in the rendering).

The show continues with the frame of the lyre itself, rendered in the opening image as a parallelogram topped by a “T.” When I see the constellation, I don’t see the “T” as much as I see an additional triangle composed of Vega, ζ1 Lyr (a double-star that connects the triangle to the parallelogram), and ε1a/ε2a Lyr (far left of the image above, connected by the red line). Now then, ε1a/ε2a Lyr is a sight to behold in a telescope, as it is not one star, but instead a pair of binaries, meaning four stars total that resolve nicely under reasonable magnification (it is reported that, under ideal conditions, the two pairs themselves can be split naked eye). This famed “double-double” star is shown below in an image from the Harrison Telescopes website.

Vega is the fifth brightest star in the Night Sky (making it the sixth brightest star in our sky) and is the second star to appear during the summer months after Arcturus. During June and July, Vega first appears high in the North-Eastern Sky and is obvious to anyone waiting at Darling Hill for their eyes to adjust after sunset. This makes Vega an easy marker for anyone learning the Summer constellations, which then makes Lyra an easy constellation to get under one’s belt at the same time. The parallelogram (where one might imagine the plucked strings of the lyre to be) is oriented nearly North-South and runs along the neck of Cygnus the Swan, a Constellation embedded well into the river of stars that make up the Milky Way.

With the constellation of Lyra identified from its two prominent geometric themes, the search for the subtle tones in this constellation can continue. After M13 in Hercules and the famous M31, the object I learned to identify from the relative positions of stars was M57, the Ring Nebula. M57 sits like a tuning knob at the base of Lyra, almost centrally located between the binary star Sheliak and Sulafat. While far from the brightest object in the night sky, the Ring jumps out immediately even under low-power binoculars as something clearly not a pinpoint of light. New scope owners looking to find anything(!) in their scope are well-advised to consider M57 as a target for low-magnification observing, as the appearance of Sheliak and Sulafat in an eyepiece help to set bright boundary conditions between which to scan for the nebulous ring. On ideally clear and steady nights, the central star of the Ring is visible, although this can be a heroic undertaking for even seasoned pros. A comparison of what Hubble sees and what you’ll likely see is provided on the previous page.

Containing the Ring Nebula would be enough for any constellation to be noteworthy to an amateur astronomer, but Lyra is famous as being a host to yet another Messier object in the form of M56, captured above-right by Stu Forster in July of 2010. This small globular cluster has been tagged at 13.7 billion years of age and can be found most easily by drawing a straight line between Sulafat and Alberio (the head of Cygnus the swan) and scanning the midpoint with larger-aperture binoculars or a small telescope.

For those listening most intently to the orchestrations of this constellation, the irregular galaxy NGC 6745 is just visible in medium-sized telescopes (shown above from Hubble). NGC 6745 is decidedly less J. S. Bach and decidedly more John Cage, as 6745 is actually three galaxies in the process of a violent dance. Like a famous Big Band moving through a town of jazz combos, the largest galaxy is pulling stars from the two smaller galaxies, populating itself at the expense of the disrupted musicians.

There are even themes implied but not heard that enhance the complexities of Lyra. To date, over 13 exoplanets have been discovered in Lyra, at least three of which are attributed to the position of the Kepler Mission observing envelop just beyond Cygnus (see the image above, which shows Kepler frames just to the edge of Lyra).
