Mars Slides Behind Moon This Month

In mid-February, a waning crescent Moon glides among Mars, Jupiter, and Saturn in the predawn sky. For many viewers in North America, the Moon actually covers Mars on February 18th.

It’s fitting that with my intense focus on Malacandra throughout January that upon finishing the Mythgard Academy class this week I have a major astronomical event featuring Mars to look forward to in less than two weeks.

I can take good advantage of this occultation since I live in the middle of the country just shy of 40 degrees north latitude. If I were visiting my daughter in the Pacific Northwest, I’d have a bit more dark time but might not see it as well being at a more northern latitude at 47 degrees.

Actually, not just Mars will be in the spotlight in mid-February. Three planets are center stage in the predawn skies starting February 18th (see first graphic above). Listen to Sky Tour courtesy Sky & Telescope for some viewing tips and other astronomical tidbits for February observing.

My only concern will be the weather, which in February in Kansas, is dodgy at best.

Keeping my fingers crossed and as always keep looking up!

Welcome to Winter Solstice Eve Morning

Good morning and welcome to the last half day before Winter. Officially, Winter begins tonight after ten o’clock (Central time)

Winter Solstice 2019 Countdown

Enjoy the shortest day of the year because I’m looking forward to the longest, darkest night of the year – every amateur astronomers dream.


Today, my son, daughter-in-law and grandson are driving here from Texas. They left before dawn and we anticipate their arrival late this afternoon.

With the help of my daughter, who arrived earlier this week, my main floor living area is mostly baby proof. And the new furniture was delivered Thursday afternoon. And Friday, Rachelle setup the Christmas tree and last night over home-made pizza we decorated (or rather she decorated because she’s the artistic one).

Rachelle and I will spend part of the day shopping, taking advantage of her Costco membership to stock up on food she can eat (corn allergy) and for the rest of the family as well. While I have a Christmas goose in the freezer, I need to plan for other meals and sides. Instead of just Terry and I to feed, I’ll have three to four times that many to provide for.

So we are ready for family gathering and making new memories until we once again scatter back to our nests for the new year.

Dark Seas and Bright Highlands

On the basis of lunar rocks brought back by the astronauts, explain why the maria are dark-colored, but the lunar highlands are light-colored?

Regions of both the near side and far side of the Moon not covered by mare basalt are called highlands. The highlands consist of the ancient lunar surface rock, anorthosite, and materials thrown out during the creation of the impact basins. (“Lunar Rocks | National Air and Space Museum,” n.d.)

The anorthosite rock highlands are brighter than the maria basalts.  Pulverized by meteoric action, both the basalts of the maria and the anorthosite of the highlands are covered by a blanket of powdered rock, also known as regolith. Continue reading “Dark Seas and Bright Highlands”

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.

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!

 

 

Full Moon Merry Christmas

Tomorrow, just after six o’clock in the morning and just as the sun is rising, we’ll experience the first full moon to occur on Christmas Day since 1977.  I wasn’t even in high school yet in 1977 (although my husband was already in college by then).  If you miss opening this Christmas present, you won’t get another chance until 2034 (by which time I should be retired).

Other astronomical items of note this holiday week include:

  • On the 4th day of Christmas (Monday that is), Mercury reaches its peak distance from the sun 30 minutes after sunset in the southwest.
  • On the 5th day of Christmas (Tuesday), Saturn continues its return from behind the Sun.  Look to the southeast in the pre-dawn morning time.
  • On the 6th day of Christmas (Wednesday), look up and south to spy the Seven Sisters (aka as the Pleiades)
  • On the 8th day of Christmas (Happy New Year!), use binoculars to find Comet Catalina rising close to Arcturus (a very bright star) around midnight and continue to rise high in the southeast until dawn twilight.
  • On the 9th day of Christmas (Saturday, January 2, 2016) the Earth reaches its closest point to the Sun (at the start of Winter no less)
  • On the last day of Christmas (Twelfth Night) at 10 p.m. EST, Pluto hides behind the Sun.

Comet Catalina

May the brightest star guide you in your search for Peace, Love and Joy.

Merry Christmas!

 

 

 

Timelapse Lunar Eclipse Over Downtown Kansas City by Tom Martinez

Published by Tom Martinez, Historian of the Astronomical Solemnity of Kansas City, on Apr 7, 2015

The total phase was not seen from KC since totality occurred after moonset. Crystal clear skies allowed for a nice view of the last sliver of moon, however. Music is “Alive” by Jahzzar, http://betterwithmusic.com.

Look West After Sunset Tomorrow Evening

I probably won’t get to see this.  Snow is forecast for this afternoon in the KC metro area and continuing cloud cover for the next couple of days.  I’ll keep my fingers crossed and my eyes on the western horizon as I drive home tomorrow night.

For those of you with clear skies, enjoy a triple conjunction of the bright planet Venus, the red planet Mars and the two-old new Moon.

Whatever you do, just start watching the western twilight sky. Set a reminder on your phone if need be. The planets and moon won’t be up for long after sunset. And the views will be spectacular from now through Saturday night!
