Was Last Night’s Moon Blue for You?

Last night’s full Moon was a “Blue Moon” — where the Moon isn’t really blue, but is the name for when there is a second full Moon in a month. Normally, we only get one full Moon a month, but every 2 1/2 years or so, the calendar lines up just right, since the time between full moons is 29.5 days while most months are 30 or 31 days. Since we had a full Moon on August 2 and a second one last night on August 31,

Of course the Moon has reason to be “blue” (if we want to anthropomorphize a little) with the recent death of the first Moonwalker, Neil Armstrong. And sometimes the Moon can actually appear to be blue if volcanic ash or forest fire ash are in the atmosphere in your location, since ash particles can scatter away all the warm colors in Moonlight, leaving a pale blue tint to the Moon.

Our readers sent in their Blue Moon images from last night, and some, like the one above, used a little image editing magic to make the Moon appear blue, but most are just gorgeous images of our closest neighbor and constant companion in space.

Dramatic New Video Brings You to the Dazzling Lunar Surface

This video has been in production for a while and was not originally meant to honor Neil Armstrong, but it very well could memorialize the first human explorer to set foot on the Moon. This short video titled “From the Earth to the Moon” provides a stunning and inspirational view of the lunar surface, and “highlights vast portions of the lunar surface that have yet to be explored, and demonstrates how new images are revealing dramatic details of future landing sites suitable for both robotic and human missions,” writes lunar scientist David Kring, one of the researchers behind creating this video.

All of the footage is from actual images and data from the Lunar Reconnaissance Orbiter; there are no artist renditions or animations.

“The scenes in the video are so dramatic that you may find yourself reaching out to pick up a rock and becoming restless to walk among the lunar peaks,” writes Kring.

As stunning as the video is, it also reminds us that humans have not visited its surface since 1972, even though it is one of the best and most accessible place in the solar system to explore the fundamental principles of our origins, Kring says.

Most of the images and topographical data were obtained in particular by the NASA Lunar Reconnaissance Orbiter Camera (LROC) and Lunar Orbiter Laser Altimeter (LOLA) teams, and rendered by Kring’s team and the Goddard Space Flight Center Scientific Visualization Studio.

Here’s what you are seeing in the video:

The video provides views of (i) the lunar nearside, (ii) a flyover of the heavily cratered lunar highlands, (iii) Oceanus Procellarum, (iv) a zoomed-in perspective of Aristarchus crater, (v) a flight down Vallis Schröteri, (vi) an oblique perspective of Aristarchus crater, (vii) crater walls within Aristarchus, (viii) a pull away perspective of Aristarchus crater, (ix) a zoomed-in rotating view of Tycho crater, (x) flybys of five central peak features within Tycho crater, (xi) a pull away perspective of Tycho crater with distinct panels of images to illustrate a variety of spatial resolutions and albedo, (xii) a rotating view of Tycho crater from a position slightly above its rim, (xiii) a pull away perspective of Tycho crater, (xiv) rotating perspective of Orientale basin, (xv) rotating and pull away perspective from Orientale basin, (xvi) dawn rising over Tsiolkovsky crater, and (xvii) Earth rising over the lunar surface.

Kring leads the Center for Lunar Science and Exploration, and is also well known for another discovery: he was part of the team that discovered the Chicxulub impact crater, and helped link the crater and its ejecta to the K-T boundary mass extinction of dinosaurs and over half of the plants and animals that existed on Earth 65 million years ago.

Let’s Send Neil Back To The Moon

As a native-born and life-long resident of Ohio, I have lived in the shadow of Neil Armstrong all my life. I visit Wapokenta every few years for two simple reasons – I love the Armstrong Museum and I feel a need to pass that heritage on to children, grandchildren and visiting friends. Of course, I was crushed when I read of his death. I would have given anything to have had Armstrong’s autograph on my original Apollo landing newspapers, or even just to have seen the man. He was a humble hero… and this is the quality that I loved most about him. However, Neil Armstrong and his quiet ways didn’t just impact my life. He touched us all.

“Early on Sunday morning here in Australia I got the news I never wanted to hear.” says Dave Reneke of Australia. “I was in the middle of a radio interview on a local station when they cut in with the news that Neil Armstrong had passed away. “What?? What are you telling me…Neil’s dead!!” I cut the interview short because I simply couldn’t go on.

Neil Armstrong wasn’t just an American hero; he belonged to the entire world. Kids wanted to be like him. Men looked up to him and every woman wanted to be Mrs. Neil Armstrong. My world had just collapsed and I didn’t know what to do.

A humble man who, as a kid, only ever wanted to fly, Neil went on to pilot the famous X-15 rocket plane, fly dozens of dangerous missions during the Korean War and later travel in space with Dave Scott on the Gemini 8 mission in 1966. He was unknowingly paving the way for his ultimate destiny to be the first man to walk on the Moon a mere 3 years later.

There will never be another event like this. If anything epitomises the twentieth century it was the first Moon landing. Our first steps on another world. Those of us who witnessed it remember where they were at the time, just as we did when Elvis died and Kennedy was assassinated. Tragedy imprints, indelibly!

For 12 hours during and throughout that moon walk period there was virtually no crime around the world. One in six human beings were watching the moon landing on TV, even the crims, and listening on radios. For a moment in time we were united – we knew, we just knew we were witnessing one of the greatest events in history unfold right before our very eyes.

You only get one shot at this. Only one person can walk on the moon for the first time. It took guts – the ‘right stuff!’ Neil gave them a 50/50 chance of getting to the Moon and getting back. Nasa’s odds were about the same. They were both 38 years old with families and a whole lifetime in front of them, but they went.

I was lucky enough to be invited to spend the morning with Buzz Aldrin at his home in California in 2008, prior to writing a story about the upcoming 40th anniversary of Apollo 11. I remember asking Buzz what concerned them the most, what was the one thing they were concerned about and feared the most.

Both he and Neil had two days cooped up in a small capsule to think about that. He paused, looked up and surprised me by saying they were very aware they were being watched. “We knew that everything we did and everything we said was being recorded for future history,” Buzz said. “It was on our minds constantly.”

OK, it’s over. Neil Armstrong’s name will live on from this day forward. He’s gone beyond the term legend. In the annals of history he’ll be seen as a giant, the Wilbur Wright of our time. Hundreds of years from now kids in a future classroom will be learning about Neil Armstrong, as we studied ancient history in our day.

But hang on, do we leave it all here? Is this where the story ends? Let’s do something about it, something quite radical but completely sensible. Let’s send Neil Armstrong back to the Moon! Not literally but posthumously. Let’s start a movement that will reverberate back to NASA, to the white house and engage a lobby group to have Neil Armstrong’s ashes interred on the Moon.

I’m proposing a monument to be built on the Sea Of Tranquillity, on the spot where Neil and Buzz walked and, if there’s no national burial planned, place his ashes there. An eternal symbol and testament to human accomplishment – as Neil put it, the place where men from planet Earth first set foot on the Moon, and came in peace for all mankind.

Let it be slated for the first Moon return mission, by any country or private consortium. A stone minimally inscribed with a simple message telling the story for future generations. The blood, sweat, tears and spirit of countless thousands who worked on the Moon missions would be indelibly imprinted on it. Even the words ‘Neil and Buzz were here’ would satisfy me.

We’ve got the ‘Monument to a Century of Flight’ located at the Aycock Brown Welcome Centre at milepost 1.5 in Kitty Hawk, NC, the Smithsonian cradles flight history and the ashes of people like Gene Rodenberry, James Doohan et al circle the earth in tributary gestures.

Neil’s remains would be in good company on the Moon sharing the eternal silence with the ashes of Eugene Shoemaker. If you just asked “who” Google the name, it’s a great story. Folks, this is not something we need to do, it’s something we should do!”

Blue Moon This Week

A Blue Moon. Credit:

When you hear someone say “Once in a Blue Moon” you know what they mean. They’re usually talking about something rare, silly, and even absurd. After all, when was the last time you saw the Moon turn blue? Well, rare or not, we’re having one this week, and according to astronomer David Reneke writer and publicist for Australasian Science magazine, a Blue Moon is slated for the last day of this month, Friday, August 31.

It’s not at all clear where the term ‘Blue Moon’ comes from. According to modern folklore it dates back at least 400 years. A Blue Moon is the second Full Moon in a calendar month. “Usually months have only one Full Moon, but occasionally a second one sneaks in, David said. “Ancient cultures around the world considered the second Full Moon to be spiritually significant.”

Full Moons are separated by 29 days, while most months are 30 or 31 days long, so it is possible to fit two Full Moons in a single month. This happens every two and a half years, on average. By the way, February is the only month that can never have a Blue Moon by this definition. We had one Full Moon on August 2 this year and the second will be Friday night.

Does the Blue Moon actually turn blue? No. Physically colored Blue Moons are rare, and that’s where the phrase comes from, “Once in a Blue Moon”. There are occasions though when pollution in the Earth’s atmosphere can make the Moon appear to look blue in color. The extra dust scatters blue light. For example, the Moon appeared bluish green across the entire Earth for about 2 years after the eruption of Krakatoa in 1883.

There were also reports of a blue-green coloured Moon caused by Mt. St. Helens in 1980 and Mount Pinatubo in 1991. “So in a sneaky sort of way, it could be true,” Dave said with a grin. Look up at the night sky on August 31 and see for yourself. Everywhere in the world the full Moon rises in the east just as the Sun is setting in the west.

“Blue Moons don’t have any real significance scientifically but they’re fun to look at,” David said. “Anytime you can get people out to look at the real sky to me is a great plus, enjoy it while you can this Friday night and while you’re looking moonward, think of Neil Armstrong, OK?”

Weekly SkyWatcher’s Forecast: August 27-September 2, 2012

Greetings, fellow SkyWatchers! If you only get your telescope or binoculars out once in a Blue Moon, then get them out this week when a Blue Moon actually happens! However, if you can’t wait, then let’s explore some great lunar features, bright star clusters and great double stars. When you’re ready to learn some history, mystery and more, then just step on inside…

Monday, August 27 – Tonight the waxing Moon’s most notable features will be the vast area of craters dominating the south-central portion near and along the terminator. Now emerging is Ptolemaeus – just north-northeast of Albategnius. This large round crater is a mountain walled plain filled with lava flow. With the exception of interior crater Ptolemaeus A, binoculars will see it as very smooth. Telescopes, however, can reveal faint mottling in the surface of the crater’s interior, along with a single elongated craterlet to the northeast. Despite its apparent uniformity, close inspection has revealed as many as 195 interior craterlets within Ptolemaeus! Look for a variety of interior ridges and shallow depressions.

With the Moon low to the southwest, we have a chance to go northeast to Cepheus for a new study – NGC 7160 (Right Ascension: 21 : 53.7 (hours : minutes) Declination: +62 : 36). At magnitude 6.1, this small open cluster is easily identified in scopes and may be seen as a faint starfield in binoculars. You’ll find it about a finger-width north of Nu Cephei.

Tuesday, August 28 – In 1789 on this day, Sir William Herschel discovered Saturn’s moon Enceladus.

On the lunar surface tonight, we’ll start by following the southward descent of large crater rings Ptolemaeus, Alphonsus, and Arzachel to a smaller, bright one southwest named Thebit. We’re going to have a look at Hell…

Just west of Thebit and its prominent A crater to the northwest, you see the Straight Wall – Rupes Recta – appearing as a thin, white line. Continue south until you see large, eroded crater Deslandres. On its western shore, is a bright ring that marks the boundary of Hell. While this might seem like an unusual name for a crater, it was named for an astronomer – and clergyman!

Once you’ve been to Hell, let’s go to the heavens for NGC 7235 (Right Ascension: 22 : 12.6 – Declination: +57 : 17). Locate the star crowded area of Epsilon Cephei which will also include this 7.7 magnitude open cluster in the same low power field. Give it a try. Look for a small, rectangular assortment of 10th magnitude and fainter stars, including a beautiful ruby red, west-northwest of Epsilon.

Wednesday, August 29 – Due south of mighty Copernicus on the eastern edge of Mare Cognitum, you will see a ruined pair of flattened craters. They are Bonpland and Parry – with Frau Mauro just above them. The smallest and brightest of these ancient twins is the eastern Parry. Have a look at its south wall where a huge section is entirely lost. It was near this location that Ranger 7 ended its successful flight in 1964. Just south of Parry is another example of a well-worn Class V crater. See if you can distinguish the ruins of Guericke. Not much is left save for a slight U-shape to its battered walls. These are some of the oldest visible features on the Moon!

If you’d like to head for something very young, have a look at 6.8 magnitude open cluster NGC 6811 (Right Ascension: 19 : 37.3 – Declination: +46 : 23) in Cygnus. This mid-sized, unusually dense open cluster is found less than finger-width north-northwest of Delta – the westernmost star of the Northern Cross. Like most open clusters, the age of NGC 6811 is measured in millions, rather than billions, of years. Visible in binoculars on most nights, telescopes should show a half dozen or so broadly-spaced resolvable stars overlaying a fainter field. Be sure to return again on a moonless night, and have another look a disparate double Delta!

Thursday, August 30 – Today celebrates the Yohkoh Mission, launched in 1991. It was a joint effort of both Japan and the United States to monitor solar flares and the corona. While its initial mission was quite successful, on December 14, 2001 the signal was lost during a total eclipse. Unable to reposition the satellite back towards the Sun, the batteries discharged and Yohkoh became inoperable.

While the graceful Gassendi will try to steal the lunar show tonight, let’s have a go at Foucault instead. To find it, head north to Sinus Iridum and locate Bianchini in the Juras Mountains. Just northeast, and near the shore of south-eastern Mare Frigoris, look for a bright little ring.

Physicist Jean Foucault played an instrumental role in the creation of today’s parabolic mirrors. His “Foucault knife edge test” made it possible for opticians to test mirror curves for optical excellence during the final phases of shaping before metallization. Thanks to Foucault’s insight, we can turn our telescopes on such difficult double stars as Beta Delphini and resolve its 0.6 arc-second distant 5.0 magnitude companion. A challenge for smaller scopes is MU Cygni. This 4.5 and 6.0 magnitude pair should be resolvable in any scope that passed Foucault’s test!

Tonight let’s view a double star, Eta Lyra. Just on the edge of unaided visibility, you will find it around three finger-widths due east of Vega. This wide, disparate pair of 4.5 and 8.0 magnitude stars should be resolvable in just about any scope, but is beyond the reach of binoculars.

Friday, August 31 – Tonight we will begin entering the stream of the Andromedid meteor shower, which peaks off and on for the next couple of months. For those of you in the northern hemisphere, look for the lazy “W” of Cassiopeia to the northeast. This is the radiant – or relative point of origin – for this meteor stream. At times, this shower has been known to be spectacular, but let’s stick with an accepted fall rate of around 20 per hour. These are the offspring of Beila’s Comet, one that split apart leaving radically different streams – much like 73/P Schwassman-Wachmann did last year. These meteors have a reputation for red fireballs with spectacular trains, so watch for them in the weeks ahead.

It’s Blue Moon! That doesn’t mean the Moon is going to be colored any differently – it just means it’s the second full Moon within a month.

Think having all this Moon around is the pits? Then let’s venture to Zeta Sagittarii and have a look at Ascella – “The Armpit of the Centaur.” While you’ll find Zeta easily as the southern star in the handle of the teapot formation, what you won’t find is an easy double. With almost identical magnitudes, Ascella is one of the most difficult of all binaries. Discovered by W. C. Winlock in 1867, the components of this pair orbit each other very quickly – in just a little more than 21 years. While they are about 140 light-years away, this gravitationally bound pair waltz no further apart than our own Sun and Uranus!

Too difficult? Then have a look at Nu Sagittarii – Ain al Rami, or the “Eye of the Archer.” It’s one of the earliest known double stars and was recorded by Ptolemy. While Nu 1 and Nu 2 are actually not physically related to one another, they are an easy split in binoculars. Eastern Nu 2 is a K type spectral giant that is around 270 light-years from our solar system. But take a very close look at the western Nu 1 – while it appears almost as bright, this one is 1850 light-years away! As a bonus, power up in the telescope, because this is one very tight triple star system!

Saturday, September 1 – On this day 1859, solar physicist Richard Carrington (who originally assigned sunspot rotation numbers) observed the first solar flare ever recorded. Naturally enough, an intense aurora followed the next day. 120 years later in 1979, Pioneer 11 made history as it flew by Saturn.

While the Moon essentially appears to be full throughout the night, take the time to compare the western and eastern limbs. To the west, you will see the smooth arc no longer displays high contrast features. To the east you should see a broken edge now in sunset. Watch in the days ahead as many of your favorite craters begin to reveal themselves in a “different light.”

Tonight let’s visit Alya. One of the fainter stars to receive a proper name, Theta Serpens Caput is located around a hand span due east of Beta Ophiuchi. Thankfully, resolving this wide, matched magnitude pair is easier than finding it. If you have high power, self-stabilizing binoculars, this one could be real fun!

Sunday, September 2 – It won’t be long until the Moon lights the skies, so let’s have a look at disparate double Kappa Pegasi. It’s the westernmost star of northern Pegasus and is around a hand span due south of Sadr – the central star of the Northern Cross. At magnitude 4.3, look for a faint companion leading the orange-yellow primary across the sky. This one could be tough for small scopes – so make a challenge of it!

Now let’s have a look at Beta and Gamma Lyrae – the lower two stars in the “Harp.” Beta is actually a quick change variable dropping to less than half the brightness of Gamma every 12 days, but for a few days the two stars appear to be of near equal brightness. Beta is a very unusual eclipsing spectroscopic binary. Its unseen companion may be a “collapsar.”
Before you call it a night, head a finger-width north of Omicron Andromedae for 15 Lacertae. Just on the edge of unaided visibility, this carbon star is also a disparate double. The 5.2 magnitude variable primary will appear more red at its faintest, but its 11.0 magnitude companion is the faintest of all!

But don’t put the telescope away just yet. If you can locate the Moon, you can locate Uranus! Just take a look about 3 degrees away to lunar south to catch the slightly greenish orb of the outer planet.

Until next week, ask for the Moon… But keep on reaching for the stars!

In memory of Neil Armstrong, First Man to set foot on the Moon, here’s a summary of Apollo 11 highlights and a collection of some tributes and photos to celebrate his life and the indelible inspiration he gave to current generations and all those yet to come to take up the noble torch for science and exploration. He became an everlasting icon for the ages when he took, “one giant leap for mankind”, and accomplished one of the greatest feats in human history.

Armstrong passed away at age 82 on Saturday, August 25, 2012 due to complications from heart bypass surgery.

Neil Armstrong was the commander of the three man crew of Apollo 11, which included Buzz Aldrin and Michael Collins.

The trio blasted off on their bold, quarter of a million mile moon mission from Cape Canaveral, Florida on July 16, 1969 to fulfill the lunar landing quest set by President John F. Kennedy early in the decade.


Armstrong and Aldrin safely touched down at the Sea of Tranquility on the lunar surface on July 20, 1969 as hundreds of millions across the globe watched in awe and united in purpose.

“Houston, Tranquility Base here. The Eagle has landed !,” Armstrong called out and emotional applause erupted at Mission Control – “You got a bunch of guys about to turn blue.”

Armstrong carried all of humanity with him when he stepped off the footpad of NASA’s Apollo 11 Lunar Module and became the first representative of the human species to walk on the surface of another celestial body.

His first immortal words,

“That’s one small step for [a] man, one giant leap for mankind.”

During their 2 ½ hours moonwalk Armstrong and Aldrin unveiled a plaque on the side of the lunar module. Armstrong read the words;

“Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

The duo collected about 50 pounds (22 kg) of priceless moon rocks and set out the first science experiments placed by people on another world.

Altogether Armstrong and Aldrin spent about 21 hours on the moon’s surface. Then they said goodbye to the greatest adventure and fired up the LM ascent engine to rejoin Michael Collins circling above in the Apollo 11 Command Module.

Tributes to Armstrong have been pouring in – He is often described as a reluctant hero who gave credit to others.

“Armstrong, the lunar Adam,” wrote Virginia Adams

In a statement, NASA Administrator Charles Bolden said in part,

“As long as there are history books, Neil Armstrong will be included in them, remembered for taking humankind’s first small step on a world beyond our own.

“Besides being one of America’s greatest explorers, Neil carried himself with a grace and humility that was an example to us all. When President Kennedy challenged the nation to send a human to the moon, Neil Armstrong accepted without reservation.

“As we enter this next era of space exploration, we do so standing on the shoulders of Neil Armstrong. We mourn the passing of a friend, fellow astronaut and true American hero.”

Armstrong’s family released a statement that said in part;

“We are heartbroken to share the news that Neil Armstrong has passed away following complications resulting from cardiovascular procedures.

“Neil was our loving husband, father, grandfather, brother and friend.

“Neil Armstrong was also a reluctant American hero who always believed he was just doing his job. He served his Nation proudly, as a navy fighter pilot, test pilot, and astronaut. He also found success back home in his native Ohio in business and academia, and became a community leader in Cincinnati.

“For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.”

“He was the best, and I will miss him terribly,” said Michael Collins, Apollo 11 command module pilot.

Buzz Aldrin, Apollo 11 lunar module pilot, released a statement that said in part,

“I am very saddened to learn of the passing of Neil Armstrong today. Neil and I trained together as technical partners but were also good friends who will always be connected through our participation in the Apollo 11 mission. Whenever I look at the moon it reminds me of the moment over four decades ago when I realized that even though we were farther away from earth than two humans had ever been, we were not alone. Virtually the entire world took that memorable journey with us.”

In the statement released by the family of Neil Armstrong following his death, they said, “For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the Moon smiling down at you, think of Neil Armstrong and give him a wink.”

In the spirit of that request, we asked our readers to send in any pictures they took of the Moon last night while they thought of Neil and gave him a wink

Lunar and Planetary Conjunction on August 21, 2012

Last night — if you were in a good location — the Moon, Spica, Mars, Saturn all came together in a lunar/planetary/stellar conjunction. My attempts to see it and capture it failed because of trees (the conjunction took place low on the horizon), but thank goodness for our astrophotographer friends! John Chumack caught the event from his observatory in Ohio (his specs: Canon Rebel Xsi 85mm Lens at F5.6, ISO 400, 1 second exposure) and Ian Musgrave captured the view in Australia, below.

Seeking the Moon’s Rare Atmosphere

Using the dim light of distant stars reflecting off of the surface of the Moon, scientists using a spectrometer aboard NASA’s Lunar Reconnaissance Orbiter have found traces of the Moon’s tenuous atmosphere. But don’t expect to take off your protective spacesuit. The Moon’s atmosphere is made of helium.

“The question now becomes, does the helium originate from inside the Moon, for example, due to radioactive decay in rocks, or from an exterior source, such as the solar wind.” says Dr. Alan Stern, LAMP principal investigator and associate vice president of the Space Science and Engineering Division at Southwest Research Institute, Boulder, Colo.

Scientists designed the Lyman Alpha Mapping Project (LAMP) spectrometer aboard LRO to map the lunar surface but the confirmation that helium surrounds Earth’s largest natural satellite was a bonus, Stern told Universe Today.

“LAMP was designed to simply do what we had not done in 40 years; to look closely at the surface of the Moon,” Stern said. “This really is a breakthrough, a capability discovery.”

LAMP’s findings support work done by the Lunar Atmosphere Composition Experiment, or LACE, that was left behind by Apollo 17 astronauts in 1972. LAMP is designed to examine far ultraviolet emissions in the tenuous atmosphere above the Moon’s surface.

Some elements found on the Moon, such as carbon or sodium, can be studied from Earth. Helium is not one of these, Stern says. Helium only shows very weakly in the far ultraviolet part of the spectrum. The signature is too weak to be seen from the 250,000 miles separating the Moon from Earth. Earth’s ozone layer also absorbs ultraviolet radiation making detection from ground-based detectors impossible.

And with LAMP moving over the lunar surface, we can see more than we’d see with a simple lander, Stern said.

During its mission, LACE detected argon but so far only helium has been confirmed from LAMP’s spectrograph. Although, the noble gas argon is much fainter than helium to the spectrograph, LAMP will seek this and other gases as well.

Weekly SkyWatcher’s Forecast: August 20-26, 2012

Greetings, fellow SkyWatchers! It’s going to be a great week to catch up on your lunar studies, but be sure to mark your calendar for Tuesday’s splendid conjunction! There will be bright stars and clusters to study, so enjoy these temperate nights while they last! Whenever you’re ready to learn more about the history, mystery and majesty of what’s out there, meet me in the back yard…

Monday, August 20 – Tonight the Moon sets by skydark, but if you’re looking for a lunar challenge, return to crater Petavius about one-third the way up from the southern cusp just after sunset. This ancient crater is a wonderland of detail when lying on the terminator. Look for its rugged walls interrupted by crater Wrottesley to the northwest and elongated Palitzsch southeast. If conditions are stable, power up to look for a massive, multi-peaked central mountain region, along with a deep scar – Rima Petavius – cutting diagonally across the wavelike floor.

When the Moon has set, look for the southern Crown – Corona Australis. Its hidden jewel is 7.3 magnitude, 28,000 light-year distant globular cluster NGC 6723 (Right Ascension: 18 : 59.6 – Declination: -36 : 38). Discovered on June 3, 1826 by James Dunlop of New South Wales, Australia, NGC 6723 can be best found by heading less than 7 degrees due south of Zeta Sagittarii. This mid-sized cluster gives a surprising view, but if you’re more north, best catch it at its highest.

Now, relax! Tonight is the peak of the Kappa Cygnid meteor shower. Although the Moon will interfere early in the evening, wait until it has set and watch the area near Deneb. Discovered in the late 1800?s, the Kappa Cygnids are often overlooked because the grander, more prolific Perseids tend to get more attention. Although the stream has been verified, peak dates and fall rates vary from year to year. The average fall rate is usually no more than 5 per hour, but it is not uncommon to see 12 or more per hour with many fireballs. The stream’s duration is around 15 days. Clear skies!

Tuesday, August 21 – Deep Blue Celestial Scenery Alert! Don’t goof around tonight. Find yourself an open western horizon and be outside at sky dark for the awe inspiring combination of the Moon, Spica, Mars and Saturn. The powerful blue/white star will be located just northeast of the lunar edge while Mars resides to the east/southeast and Saturn reigns above them all. This will be a very photographic opportunity, so be sure to take advantage of this splendid conjunction. Tell your family and friends!

Although we have traveled this road before, let’s go further south than last night’s lunar study and have another look at Furnerius. Shallower and less impressive than Petavius, Furnerius will fade to obscurity as the Moon waxes. This flooded old crater has no central peak, but a much younger crater has punched a hole in its lava-filled floor. Look for the long “crack” extending from Furnerius’ north shore to crater rim. Perhaps it was caused by the impact? Sharp-eyed observers with good conditions and high power will also spot a multitude of small craters within and along Furnerius’ walls. For binocular viewers, try spotting crater Stevinus to the north and Fraunhofer to the south.

Now let’s go have a look at a star buried in one of the spiral arms of our own galaxy – W Sagittarii…

Located less than a fingerwidth north of Gamma, the tip of the “teapot spout,” W is a Cepheid variable that’s worth keeping an eye on. While its brightness only varies by less than a magnitude, it does so in less than 8 days! Normally holding close to a magnitude 4, nearby field stars will help you correctly assess when minimum and maximum occur. While it’s difficult for a beginner to see such changes, watch it over a period of time. At maximum, it will be only slightly fainter than Gamma to the south. At minimum, it will be only slightly brighter than the stars to its northeast and southwest.

While you watch W go through its changes – think on this: not only is W a Cepheid variable (a standard for distance measurements), but it is also one that periodically changes its shape. Not enough? Then think twice… Because W is also a Cepheid binary. Still not enough? Then you might like to know that recent research points toward W having a third companion as well!

Wednesday, August 22 – On the lunar surface tonight, head to the eastern shore of Mare Nectaris to catch an easily noticed broken black line. This is the western flank of the Pyrenees Mountains which stretch close to 350 kilometers north to south. The black line you see is a good example of a lunar scarp, a feature more like a cliff than a true mountain range. This scarp ends to the north in crater Guttenberg. Just south of Guttenberg, you will find high contrast Santbech.

Although it will be tough to locate with the unaided eye thanks to the Moon, let’s take a closer look at one of the most unsung stars in this region of sky – Eta Sagittarii. This M-class giant star will show a wonderful color contrast to binoculars or scopes, being slightly more orange than the surrounding field. Located 149 light-years away, this irregular variable star is a source of infrared radiation and is a little larger than our own Sun – yet 585 times brighter. At around 3 billion years old, Eta has either expended its helium core or just begun to use it to fuse carbon and oxygen – creating an unstable star capable of changing its luminosity by about 4%. But have a closer look… For Eta is also a binary system with an 8th magnitude companion!

Thursday, August 23 – Do you remember a few days ago in history when Lunar Orbiter 1 was launched? Well, on this day in history it made headlines as it sent back the very first photo of Earth seen from space!

On the lunar surface tonight, we’ll return to identify Metius, Fabricus and Janssen to the south. Southwest of this trio you will see a sharply defined small crater known as Vlacq. Power up to resolve its small central mountain peak. Angling off to the west and extending westward is multiple crater Hommel. Look especially for Hommel A and Hommel C which fit nicely and precisely within the borders of the older crater. Note how many individual craters make up its borders. Just north of Hommel is Pitiscus and to its south is Nearch.

Now let’s have a look at the brightest star in the “Archer” – Epsilon Sagittarii. Known as Kaus Australis, or the “Southern Bow,” Epsilon holds a respectable magnitude 1.8 and is located around 120 light-years from Earth. This sparkling blue/white star is 250 times brighter than our own Sun. While a major challenge would be to spot Epsilon’s 14th magnitude companion star located about 32? away, even the smallest of telescopes and most binoculars can try for the 7th magnitude visual companion widely spaced to the north-northwest.

Friday, August 24 – Today in 1966 from an Earth-orbiting platform, the Luna 11 mission was launched on a three day trip. After successfully achieving orbit, the mission went on to study many things, including lunar composition and nearby meteoroid streams.

Tonight’s prominent lunar features are also Astronomical League challenges. Look southwest of previous study Theophilus for the huge form of Maurolycus. Its cratered floor may be either partially lit or fully disclosed depending on your observing time. Note especially Maurolycus’ multiple central mountains. North of Maurolycus you will see the well-eroded remains of Gemma Frisius. Its broken walls will show well under current illumination. Finally look carefully for crater Goodacre which has destroyed Gemma Frisius’ northern wall.

The Moon is now becoming the “highlight” of the night sky. Try using “higher power” to diminish some of its glare. While southwestern Sagittarius is also high, why not observe some of its other globular clusters?

Center the scope on Epsilon and sweep less than 3 degrees north-northeast to find small 7.7 magnitude globular M69 (Right Ascension: 18 : 31.4 – Declination: -32 : 21). M69 gives an appearance similar to that of other compact clusters – such as M28 and M80. Small and moderately bright, it appears coarsely textured through smaller instruments and requires larger scopes to bring out its brightest 14th magnitude members. This cluster sits near a blue 7th magnitude star which complicates seeing M69 through binoculars and finderscopes.

Now head a little more than a degree southeast, then north of a pair of 6th magnitude stars to locate NGC 6652 (Right Ascension: 18 : 35.8 – Declination: -32 : 59) – a very small 9th magnitude globular. Go less than 2 degrees northeast to find brighter (8.1 magnitude), larger M70 (Right Ascension: 18 : 43.2 – Declination: -32 : 18). Notice how more of M70?s light is concentrated in its core than M69. Continuing a little more than 3 degrees in the direction of Zeta we encounter M54 (Right Ascension: 18 : 55.1 – Declination: -30 : 29). Through a modest scope, this 7.7 magnitude globular is small, very blue, and intensely concentrated at the core. Larger amateur instruments will only bring out a few 15th magnitude members out of this globular’s faintly glowing form.

Charles Messier discovered M69 and M70 on August 31, 1780 from Paris while trying to confirm a discovery made by Lacaille using a half-inch spyglass in South Africa. These two globulars lie within 2,000 light-years of each other and less than 30,000 light-years from Earth. Due to unusual richness in metal content – for astronomers, “metals” are any elements other than hydrogen and helium – M69 may be a relatively young cluster. At some 90,000 light-years, M54 is the most distant Messier globular cluster – and may not be a globular at all – but the core of a dwarf galaxy beyond the bounds of the Milky Way! In fact M54 is intrinsically larger (300 light-years in diameter) and brighter (magnitude 10.1) than any other globular within the Milky Way itself.

Saturday, August 25 – Tonight the waxing Moon’s most notable features will be the vast area of craters dominating the south-central portion near and along the terminator. Now emerging is Ptolemaeus – just north-northeast of Albategnius. This large round crater is a mountain walled plain filled with lava flow. With the exception of interior crater Ptolemaeus A, binoculars will see it as very smooth. Telescopes however can reveal faint mottling in the surface of the crater’s interior, along with a single elongated craterlet to the northeast. Despite its apparent uniformity, close inspection has revealed as many as 195 interior craterlets within Ptolemaeus! Look for a variety of interior ridges and shallow depressions.

With the moonlight causing studies to be mildly hampered, our main feature for tonight will definitely improve once the Moon sets – so while we’re waiting, let’s drop by open cluster M29 (Right Ascension: 20 : 23.9 – Declination: +38 : 32) less than 2 degrees south-southeast of Gamma Cygni. At lower power, or through small scopes, its handful of brightest members makes this 6.6 magnitude open cluster look more like an asterism than a real group. Lacking any sense of a core, higher power and larger scopes will bring out another dozen or so stars. Those with binoculars will enjoy seeing a few of M29?s brightest stars against a vague nebulosity.

Now let’s see what the “I” can “C”… Less than 2 degrees southwest of M29 (just south of 5th magnitude P Cygni) lies another open cluster of similar brightness and size to M29 – IC 4996 (Right Ascension: 20 – : 16.5 – Declination: +37 : 38). How do these two compare? The less conspicuous IC 4996 lies in a richer Milky Way field and consists of fewer and more compact bright stars. Smaller scopes see this one as a patch of nebulosity.

Now for M55 (Right Ascension: 19 : 40.0 – Declination: -30 : 58). Found in the far reaches of eastern Sagittarius, and west-southwest of Zeta, M55 is one of the coarsest globulars known. At magnitude 7.0, M55 can be seen as a large pale ghost of luminosity in binoculars or finderscopes. This is one very open globular cluster! A multitude of fine, easily resolved stars spread oblately over the mid-power field. Long exposure photos show this to be a true globular glowing with the combined light of almost 100,000 suns.

Tonight is also the peak of the Northern Iota Aquarid meteor shower. While the Moon will totally interfere most of the evening, you still might catch a bright streak!

Sunday, August 26 – The most outstanding feature tonight on the Moon will be a southern crater near the terminator – Maurolycus. Depending on your viewing time, the terminator may be running through it. These shadows will multiply its contrast many times over and display its vivid formations. As true lunar challenge, Maurolycus will definitely catch your eye with its black interior and western crest stretched over the terminator’s darkness. Too many southern craters to be sure? Don’t worry. Maurolycus dominates them all tonight. Look for its double southern wall and multiple crater strikes along its edges. Maurolycus is found about two Crisium lengths southwest of Theophilus and in tonight’s light will appear especially fine. But look just north of Maurolycus to pick out the battered remains of Class III crater Gemma Frisius, another lunar challenge. Spanning 56 miles and descending 17,100 feet below the Moon’s surface, you’ll find its walls broken, yet enough of its northern boundary remains to clearly reveal the impact that created Goodacre. Look for the shadows which blend Goodacre and Gemma Frisius together.

On this date in 1981, Voyager 2 made a fly-by of Saturn. Eight years later in 1989, Voyager 2 flew by Neptune on this date. Why don’t we make a “date” tonight to have a look at this distant blue world? You’ll find it on the ecliptic plane. While large binoculars can pick up Neptune’s very tiny blue orb, you’ll need a telescope tonight to spot it through the lunar glare.

Until next week? Wishing you clear skies!
