Lunar Yin Yang

Another semester is upon me and my continuing pursuit of a degree.  This fall I’m seeking my science lab course credit so I decided to enroll in something I can easily get excited about:  Astronomy

The following post begins a series of weekly discussion topics I’m required to choose and post to my online Introduction to Astronomy class discussion board.  Since the formatting is very similar to that employed here at my blog, I’ll draft and publish my topics here as well.  Feel free to comment or ask questions.  I’ll do my best to answer or at least point you in the right direction.

 Near and Far, Light and Dark; the Many Sides of Our Moon

Yin and yang can be thought of as complementary (rather than opposing) forces that interact to form a dynamic system in which the whole is greater than the assembled parts. Everything has both yin and yang aspects (for instance, shadow cannot exist without light).[1]

The moon’s rotation (axial spin) matches its revolution (orbit), also known as a synchronous rotation or tidally locked. This results in the same side, the near side, always facing towards Earth. Until 1959, humans had no idea what the far side of the moon looked like.[2] Continue reading “Lunar Yin Yang”

Fantastic Fun Friday

I knew going into Friday I would have a very long day ahead of me. I had errands I needed to run first thing in the morning, so I planned to be late to work.  I stayed up past my usual bedtime, keeping my husband company.  We watched the inaugural episode of the new Amazon series “The Tick”, which is a remake of the two other Tick series from the 90s and 00s.  We also watched the latest episode of “Salvation,” which is shaping up nicely.  Not enough science, but plenty of political and personal interactions to keep the layman interested.

I forgot to turn off my alarm but didn’t mind getting up at my normal time of half past five. I did a few minutes of exercise on our elliptical and ran myself through the shower. I avoided logging in to work so I wouldn’t distract myself from the errands I needed to complete. In honor of Monday’s total solar eclipse, I wore my commemorative T-shirt produced by the Astronomical Society of Kansas City. I made sure to grab my ASKC name badge and place it in my car as I would need it for the final event on my Friday schedule.

At half past seven, I left and headed north, with a quick side trip through the car wash, which was surprisingly unbusy so early in the morning. I continued north through Lansing and most of Leavenworth until I reached the old county courthouse. I parked in the Justice Center’s parking lot and serendipitously ran into one of my book club friends on her way to work.

I walked the block back to the old courthouse and grabbed number 45 from the dispenser with about ten minutes wait time before the Treasurer’s office opened. I decided to pay the taxes and fees for my newest vehicle the old-fashioned way – in person and with a handwritten check. The number displayed as being served was 41 so I knew I wouldn’t have long to wait. I made myself comfortable on the old pew-like wooden bench and continued listening to the Dreamsnake audiobook I’d recently checked out via Hoopla.

Backyard Observing

20161021_175740
Friday evening setup: tarp (to catch falling bits and pieces in the dark) and the base.

All last week, I looked forward to the weekend as a chance to get some astronomical observing accomplished. The weather forecast seemed too good to be true: Sunny and clear, highs in the mid 70s and lows in the 50s, with dew points in the upper 40s and lower 50s. My astronomy club hosted a club star party, but I did not want to lug the scope to Louisburg and share the observing grounds with a previously scheduled private party.

Autumn Arrives and Adventures in Astronomical Observing

Autumn arrived mid-week here in the Heart of America, but you wouldn’t have known it by looking at the weather forecast:  Mid 90s and moderately high humidity.  Also with the change of the seasons, I retired my FitBit Charge (or rather it retired itself by falling apart) and upgraded to a Samsung Gear Fit2.  The new fitness tracker is spurring me on to be more active, although my sleep pattern hasn’t improved much. I can safely blame work (10 pm to 4 am conference call on a Saturday night/Sunday morning) and astronomy, which requires, well, dark skies, for my reduced snooze time.

Speaking of astronomy, I’ve upgraded, finally after two years of paralysis analysis, from the Meade ETX 90, gifted to me by my father in October 2010 (also, unsurprisingly the birth of this blog site), to an Orion SkyQuest XX14G.  Continue reading “Autumn Arrives and Adventures in Astronomical Observing”

WorldCon Withdrawals

Despite what my husband thinks, I have not over-dosed on science fiction since last Wednesday when the 74th World Science Fiction Convention (commonly referred to as WorldCon) arrived for the second time in Kansas City, Missouri.  MidAmeriCon II ended yesterday and of course the highlight of those five days was the Hugo Awards Ceremony held Saturday evening.

20160817_073751In fact, I sincerely hoped when I woke up this morning it wouldn’t be to the harsh reality of a Monday morning workday.  Ah, but life is cruel and the alternate dimension I’d enjoyed for five days evaporated into the dreary doldrums of gainful employment.  Well, not completely dreary.  Perhaps dreaded would be more like it, since I knew I’d be walking into some ‘hot potatoes’ once I strapped myself to my desk.

Grande Finale to a Grand Weekend

I’m amazed at how much I accomplished this past weekend, especially considering my husband had major surgery less than three weeks ago.

Friday Evening

TalkingTolkienTwoTowersFriday night was our first venture out on a ‘date’ since the surgery.  I signed up for a free lecture and screening at the National World War I Museum and Memorial entitled “Talking Tolkien: The Two Towers.”  We arrived about fifteen minutes early to enjoy some hors d’oeuvres and drinks.  We retired to the auditorium and waited a few minutes.  At ten minutes or so after the hour, the lecturer strolled up to the podium and gave a meandering introduction of upcoming events in a clear effort to stall.  He wanted to give the people in the lobby time to finish eating.

His lecture on Tolkien’s experiences during the Battle of the Somme was quite brief and rushed, not at all what I had been hoping for.  He further devolved into a montage of photographs from the Museum’s collection delivered in the manner of a television show’s “Previously on …” wrap of the Hobbit and the Fellowship of the Ring.  You could clearly see where Tolkien (and probably Peter Jackson) got his inspiration for scenes from Middle Earth and the conflict immortalized in the Lord of the Rings.   After the lecture, the screening of The Two Towers began, for which Terry and I stayed only about thirty minutes before deciding the movie viewing experience was better at home.

Once back home, I decided to break out the Celestron C8 I had recently borrowed from my astronomy club.  Despite dire predictions, the sky remained perfectly clear so I looked forward to an evening of planetary observing, since all five visible planets are ripe for the plucking at this time of year.  I got everything attached to the tripod and manhandled it outside to my lower patio, giving it a quick leveling and orientation north so I could get through a polar alignment swiftly.  Then I just had to wait for darkness to fall enough for me to see Polaris with my naked eye.  Continue reading “Grande Finale to a Grand Weekend”

The Majority of Americans Can’t See the Milky Way Anymore

Light pollution update.  Not looking good for looking up for 80% of us in the United States.

Tonight’s Adventure in Star Gazing with the Public

Tonight is my first night this year as a volunteer of the Astronomical Society of Kansas City in our public outreach efforts to introduce astronomical observing to the public.  Every Saturday night in May and through the end of October, we open up Powell Observatory to the public and provide education programs, solar observing, binocular observing and of course telescopic observing (weather and cloud cover permitting).  The weather forecast for this evening couldn’t be better.  See for yourself as we have our own weather station and sky cam broadcasting 24-hours a day.

Astronomy’s Sky this Week reports for tonight:

Saturday, May 14

•  The Moon moves approximately 13° eastward relative to the starry background every 24 hours, and its motion carries it near Jupiter this evening. From North America, the two appear within 5° of each other all night. They will be in conjunction at 6 a.m. EDT tomorrow morning, when our satellite passes 2° due south of the planet. Although the best views of the pair come with the naked eye or binoculars, don’t pass up the opportunity to observe Jupiter through a telescope. The giant planet’s disk currently spans 39″ and displays a wealth of atmospheric detail. All this week, Jupiter appears high in the south as darkness falls and doesn’t set until nearly 3 a.m. local daylight time. It shines at magnitude –2.2 — brighter than any other point of light in the night sky — against the backdrop of southern Leo.

While Sky and Telescope Sky at a Glance expands on: The two brightest things in the evening sky, the Moon and Jupiter, shine high just a few degrees apart this evening, as shown here. Third brightest is Mars, low in the southeast after dark.

So for a great time this evening, head south of Kansas City down US-69 to Louisburg and join me and several hundred other people as we take in the wonders of the night sky.

Keep Looking Up!

 

 

The Case of the Vanishing January

Today is the 22nd of January and of 2016.  I woke up this morning to a bitter cold Friday, to the prospect of working through most of the weekend.  Not the best way to start your day.  A huge project I’ve been involved with for many many moons is finally rolling out.  So while I’m stressed beyond belief, I’m excited to finally be able to put this project in the completed bin come Monday morning.  Then it’s on to the next “Big Thing,” er, project.

Stressful work-life aside, January wasn’t a complete loss for leisure.  I’ve read a space opera that I liked, listened to an audiobook for a book club that was interesting, read my first graphic novel for another book club and read an ebook novella (click here to see what I’ve read so far this year).  Continue reading “The Case of the Vanishing January”
