NASA Night Sky Notes for December 2018: Observe Apollo 8’s Lunar Milestones

Poster’s Note: One of the many under-appreciated aspects of NASA is the extent to which it publishes quality science content for children and Ph.D.’s alike. Your tax dollars help promote science! The following article was provided for reprinting by the Night Sky Network in December, 2018.

By David Prosper

December marks the 50th anniversary of NASA’s Apollo 8 mission, when humans first orbited the Moon in a triumph of human engineering. The mission may be most famous for “Earthrise,” the iconic photograph of Earth suspended over the rugged lunar surface. “Earthrise” inspired the imaginations of people around the world and remains one of the most famous photos ever taken. This month also brings a great potential display of the Geminids and a close approach by Comet 46P/Wirtanen.

You can take note of Apollo 8’s mission milestones while observing the Moon this month. Watch the nearly full Moon rise just before sunset on December 21, exactly 50 years after Apollo 8 launched; it will be near the bright orange star Aldebaran in Taurus. The following evenings watch it pass over the top of Orion and on through Gemini; on those days five decades earlier, astronauts Frank Borman, Jim Lovell, and Bill Anders sped towards the Moon in their fully crewed command module. Notice how the Moon rises later each evening, and how its phase wanes from full on Dec 22 to gibbous through the rest of the week. Can you imagine what phase Earth would appear as if you were standing on the Moon, looking back? The three brave astronauts spent 20 sleepless hours in orbit around the Moon, starting on Dec 24, 1968. During those ten orbits they became the first humans to see with their own eyes both the far side of the Moon and an Earthrise! The crew telecast a holiday message on December 25 to a record number of Earthbound viewers as they orbited over the lifeless lunar terrain; “Good night, good luck, a merry Christmas and God bless all of you – all of you on the good Earth.” 50 years later, spot the Moon on these holiday evenings as it travels through Cancer and Leo. Just two days later the astronauts splashed down into the Pacific Ocean after achieving all the mission’s test objectives, paving the way for another giant leap in space exploration the following year.

The Geminids, an excellent annual meteor shower, peaks the evening of December 13 through the morning of the 14th. They get their chance to truly shine after a waxing crescent Moon sets around 10:30 pm on the 13th. Expert Geminid observers can spot around 100 meteors per hour under ideal conditions. You’ll spot quite a few meteors by avoiding bad weather and light pollution if you can, and of course make sure to bundle up and take frequent warming breaks. The Geminids have an unusual origin compared to most meteor showers, which generally spring from icy comets. The tiny particles Earth passes through these evenings come from a strange “rock comet” named asteroid 3200 Phaethon. This dusty asteroid experiences faint outbursts of fine particles of rock instead of ice.

You can also look for comet 46P/Wirtanen while you’re out meteor watching. Its closest approach to Earth brings it within 7.1 million miles of us on December 16. That’s 30 times the average Earth-Moon distance! While passing near enough to rank as the 10th closest cometary approach in modern times, there is no danger of this object striking our planet. Cometary brightness is hard to predict, and while there is a chance comet 46P/Wirtanen may flare up to naked eye visibility, it will likely remain visible only via binoculars or telescopes. You’ll be able to see for yourself how much 46P/Wirtanen actually brightens. Some of the best nights to hunt for it will be December 15 and 16 as it passes between two prominent star clusters in Taurus: the Pleiades and the V-shaped Hyades. Happy hunting!

Upstate NY Stargazing In March: Two Full Moons, Venus And Mercury After Sunset – Posted To syracuse.com And nyup.com

Greetings, fellow astrophiles!

The March, 2018 UNY Stargazing article is up for your reading and sharing pleasure at syracuse.com and newyorkupstate.com:

Links: newyorkupstate.com & syracuse.com

Note that March is the best month for planning your Messier Marathon. Be sure to check your local astronomy club to see if any events are being scheduled.

There were a few evenings this past February that were unexpectedly comfortable for the time of year, hopefully giving observers some unexpectedly long opportunities to take in some of the busiest regions of our nighttime sky. To have the grouping of the Winter Hexagon – Orion, Taurus, Auriga, Gemini, Canis Minor, and Canis Major – out and about at such reasonable hours means that anyone can see not only the brightest grouping of bright stars in our yearly sky, but also some of the closest groups of stars. The Hyades star cluster, made up of the “V” of the head of Taurus the Bull – but not including the bright eye star Aldebaran – is our closest star cluster at 150 light years. Just to the northwest of the Hyades lies the second-closest bright cluster of stars to our Solar System – the Pleiades.

If you can find the Pleiades and the patch of stars under Orion’s Belt, you can even scratch two of the 110 Messier Objects off of your list. The history and some key details of the Messier Objects were discussed in the March, 2017 article. In brief – these are the bright galaxies, star clusters, and nebulae that can all be found with little more than a quality pair of binoculars, dark skies, a good star chart, and a big cup of coffee. The time around mid-March and early-April is the only time of the year when, if you start VERY soon after sunset, you can find all 110 of these objects before sunrise the next morning. Astronomy clubs the world over often plan marathons as a group – these are great opportunities to learn from seasoned amateurs as well as to see how the same object may look in many different binoculars and telescopes.

Bob Piekiel Hosts Observing Sessions At Baltimore Woods (And More!) – 2018 Observing Schedule

This event list will be added to as the year progresses. Check back often!

I’m pleased to have obtained the official schedule for Bob Piekiel’s growing observing and lecture programs for the 2018 season. For those who have not had the pleasure of hearing one of his lectures, attending one of his observing sessions, or reading one of his many books on scope optics (or loading the CD containing the massive Celestron: The Early Years), Bob Piekiel is not only an excellent guide but likely the most knowledgeable equipment and operation guru in Central New York.

The annual Perseid meteor shower, one of the year’s finest, the planets Venus, Mars, Jupiter, Saturn, Uranus, and Neptune! There is no moon in the sky so we will have fabulous views of the summer skies and southern Milky Way. Bring a lawn chair to sit and watch for meteors.
