"How To Find Two Wonders Of Summer's Skies :
The Heart Of The Scorpion
And The Heart of Our Galaxy"

Horkheimer: Greetings, greetings fellow star gazers. Did you know that any moonless night in August you can use an ancient constellation to find two incredible summer night sky sights, both the magnificent red heart of the scorpion and the incredible milky white heart of our galaxy. Let me show you.

O.K., we've got our skies set up for this week and next just after it gets dark out facing south where you'll see two of summer's most famous star patterns, a constellation which looks like a fish hook or a capital letter 'J', Scorpius the Scorpion and directly behind it several bright stars which if connected by lines would look like a teapot. Now Scorpius is officially called a constellation. But the Teapot is not. It is called an asterism, which means that it is a small pattern of stars within a constellation.

And the constellation to which the Teapot belongs is a very large pattern of stars named thousands of years ago for a mythical creature called a centaur, a creature half man and half horse. Named Sagittarius, he was known to be a great master with the bow and arrow, a centaur archer. His bow is marked by two stars of the Teapot's lid and the star at the bottom of the spout. The arrow goes from the top star in the handle through the other star of the lid with the tip of the arrow marked by the star, which also marks the tip of the spout. And with a little imagination you can see that it is aimed at the red star which marks the heart of the scorpion, Antares, which is a giant star 700 times as wide as our Sun.

But on really dark moonless nights far from city lights you'll also see that the tip of Sagittarius' arrow is embedded in the widest and densest part of that great ribbon of light called the Milky Way which stretches all the way from the southern horizon up to the zenith and back down to the northeast horizon. In fact if you look closely at Sagittarius and Scorpius you'll see that most of the Teapot and the bottom half of Scorpius are embedded in the Milky Way. And if you take a pair of binoculars and look here or anywhere along the Milky Way you will see that it is made up of millions of pinpoints of light, each one of which is a distant star which along with our Sun all belong to a giant cosmic spiral family of 200 billion stars we call the Milky Way Galaxy.

Our galaxy is shaped kind of like putting two plates face to face together, thin around the outside with a big bulge in the center. And you'll notice that when you look at Sagittarius and Scorpius that the Milky Way bulges here and is much thicker and wider than the rest of the Milky Way. And that's because the bulging center of our galaxy lies in this direction over two dozen light years away. In fact the tip of Sagittarius' arrow is pointed directly at it. So find the heart of our Milky Way Galaxy and the heart of the scorpion with the help of an ancient archer. Keep looking up!

"How To Find Two Wonders Of Summer's Skies :
The Heart Of The Scorpion
And The Heart of Our Galaxy"

Horkheimer: On any moonless night in August you can use an ancient archer's arrow to find two cosmic wonders. Look south for the fish hook shaped constellation Scorpius and directly behind it the teapot portion of Sagittarius. Sagittarius was a mythical creature, half man and half horse. A master archer whose bow and arrow are marked by the front half of the teapot. His arrow is aimed at both Antares, the giant red heart star of Scorpius which is 700 times wider than our Sun and also at the center of our Milky Way Galaxy which is the family of 200 billion stars to which our Earth and Sun belong. The Milky Way is widest between Sagittarius and Scorpius because the great bulging central hub of our galaxy lies beyond. So use Sagittarius to find the scorpion's heart and the heart of our galaxy.

Episode #10-32 /1705th Show
To Be Aired : Monday 8/9/2010 through Sunday 8/15/2010

"The Two False Comets Of Scorpius And How To Find Them"


Horkheimer: Greetings, greetings fellow star gazers. Everyone loves it when news of an approaching comet hits the press. And although I'd love to announce that there's a big comet coming, such is not the case. I can however, show you how to find two objects which are comet imposters and have fooled many people into thinking they were real. I call them the two false comets of Scorpius.

O.K., we've got our skies set up for any night this week and next in early evening when there'll be no moonlight to hide these two phonies from view, because you have to have dark skies to see them. Simply look south just after dark and you will see a fish hook shaped group of stars which is called Scorpius the Scorpion, which is one of the few star patterns which actually looks like its name. In fact it even has a bright red star Antares, right where its heart should be. Then if you follow the scorpion's body down around its tail and up to its stinger you'll be able to see two tiny fuzzy clouds, which look exactly like the heads of comets when they're far away and on their approach to Earth. In fact most comets as they make their journey toward our Earth and Sun always look like tiny q-tips nestled among the stars. But q-tips which move from night to night and get bigger and bigger as they get closer and closer and eventually develop incredibly beautiful gas and dust tails. But not these two tiny fuzzy clouds because unlike comets these two will never develop tails and they will never move in relation to the stars and they'll never get any bigger or brighter. They'll always be in the same place and look the same.

Although they have been seen for thousands of years they weren't officially named until the 18th century when an astronomer named Charles Messier who made it part of his life's work to make a list of fuzzy cloud-like objects in the heavens so that he and other astronomers would not get confused when they went comet hunting. They're objects number 6 and 7 on his "fuzzy cosmic clouds, not-to-be-confused with comets, list". And today we use the first letter of Messier's last name when we refer to them. So they are now called M-6 and M-7. Now although they really do look like decapitated comet heads to the naked eye, through binoculars they reveal themselves to be much different because they are far more grand than comets.

Indeed each tiny cloud is a great cluster of stars, other suns far, far away. The one closest to the stinger M-7 is a cluster of about 80 stars and is 800 light years away which means that the light we see now is the light that left these stars 800 years ago around 1200 a.d., 300 years before Columbus set sail. The higher cluster, M-6 also has about 80 stars in it but you'll notice that it is quite a bit dimmer. Because it is exactly twice as far as M-7, 1600 light years away, which means that the light we see now is actually the light that left these stars 1600 years ago around 400 a.d. about the time of the fall of the Roman Empire. Wow! So get thee out to see the two false comets of Scorpius this week and next while there's no bright moonlight to hide them. Keep looking up!

Horkheimer: This week and next you can see the two false comets of Scorpius. Look south in early evening for the fish hook shaped constellation Scorpius the Scorpion. Antares marks its heart and two stars mark his stinger. And just above the stinger on a dark moonless night you can see two tiny fuzzy clouds called M-6 and M-7, which look like decapitated comet heads. M-7 is actually a cluster of 80 stars 800 light years away which means the light we see right now is the light that left it in 1200 a.d. M-6 also has 80 stars but is 1600 light years away which means that the light we see now left it in 400 a.d. Wow! Use binoculars for a super close up view of these two false comets of Scorpius!

Episode # 10-33 / 1706th Show

To Be Aired : Monday 8/16/2010 through Sunday 8/22/2010

"The Mystery Of The Wandering Stars"


Horkheimer: Greetings, greetings fellow star gazers. Imagine that you are an ancient Egyptian / Babylonian / Greek or Roman and that you enjoy stargazing. The difference between stargazing back then however and stargazing now would be quite dramatic because there would be no urban lighting and no industrial pollution. So the heavens would be filled with many more stars than we can see today unless we go to the tops of the highest mountains or as far away from urban lighting as possible.

Now as an ancient human you would notice that most of the stars remain in fixed positions relative to one another and that they only change their positions in entire groups depending on the hour of the night or the season of the year. For instance whenever you looked at the stars we now call the Big Dipper they would appear to be in the same positions relative to each other as would the stars we call Cassiopeia, Orion the hunter or Scorpius the scorpion, etc. You would know where they are located at various times of the night and year. And you could even use them as a nightly and seasonal clock, which we can still do.

But there would be some stars that puzzle you. In particular five of them because not only do they slowly change their positions among the fixed patterns of stars they also change their brightness, being sometimes very dim and sometimes very bright. On top of which, one would occasionally stop, go backwards for a while, then reverse direction and go forward again. Talk about weird! Now the ancient Greeks called all the objects in the night sky 'asteres', which means 'stars'. In fact that's where we get our star shaped pattern on computers, the asterisk.

But the seven peculiar objects were given a special name from the rest. They were called 'asteres planetes'. The Greek word 'planetes' means 'wandering' so the 'asteres planetes' were the 'wandering stars', which today we simply call the planets. And in much of western civilization we still use the planet names derived from the Romans who derived their planet names from the Greeks and Babylonians. We know them as Mercury, Venus, Mars, Jupiter and Saturn plus the Moon and our Sun. Together they are known as 'The Seven Classical Planets'. And our ancestors thought they were deities, gods who could influence human behavior. And although they came up with some very clever solutions as to why they changed position none of them were correct.

Today we know these objects wander because they are so much, much closer to us than the stars and that they along with our Earth are in constant rapid orbit around the sun. And strangely every one of us still pays daily tribute to these seven ancient classical planets because the seven days of the week are named after them in almost all languages. In English Sunday is named for the Sun, Monday for the Moon, Tuesday for Mars, Wednesday for Mercury, Thursday for Jupiter, Friday for Venus and Saturday for Saturn. Think of that next Moonday when you have to get up to go to work. Keep looking up!

"The Mystery Of The Wandering Stars"


Horkheimer: Have you ever heard of stars that wander? Pretend that you're an ancient Greek or Roman and you're used to seeing the star patterns we call the Big Dipper, Orion, Scorpius, etc. and you're aware that almost all the stars remain fixed in relative position to each other although they move as groups throughout the night and year. Then imagine how bewildered you'd be at a handful of stars, which change position and wander from night to night. If you're Greek you call all the stars 'asteres' which means 'stars', however you call the ones that move 'asteres planetes', the 'wandering stars', which is where we get our word planet. So if you see a star that looks out of place you're probably seeing a planet. Keep looking up!

"Find The False Dawn Of Omar Khayyam"

Horkheimer: Greetings, greetings fellow star gazers. Almost a thousand years ago the Persian poet Omar Khayyam in his book of poetry "The Rubaiyat" wrote his most famous line "a jug of wine, a loaf of bread and thou beside me singing in the wilderness." But elsewhere in "The Rubaiyat" Omar made a poetic allusion to a mysterious "false dawn" as opposed to the real dawn, which can only be seen at a certain time of year. And this year the first two weeks of this September are your best chances to see it for 2010 because there will be no bright moonlight to overpower this delicate astronomical phenomenon. Let me tell you all about it and what you have to do to find it.

O.K. If we could go way out into space and look down on our solar system with super human vision we would notice a faint, almost imperceptible vast cloud extending outward from the Sun in the plane of the orbits of Mercury, Venus, Earth and slightly beyond, an enormous cloud of cosmic dust. And while one would expect it would be impossible to see this super faint cloud from Earth, nevertheless in September when the plane of our Earth's orbit is almost vertical to the horizon, we can under the right conditions. And those conditions require that there is no moonlight out and that you must be far away from city lights because even the faintest moonlight or urban lighting will wipe out the extremely delicate, ethereal glow of the false dawn. As a general rule if you can see the Milky Way from where you're observing you'll have a good chance to see this it.

To find it look toward the east about 2 hours before sunrise, before the real dawn. It will look like a wedge or cone-shaped dim patch of light about the same brightness as the Milky Way. And it will extend from the horizon about one third to half way up to the zenitha ghostly, faintly glowing, rounded pyramid of light. Now the scientific name of this phenomenon is the zodiacal light and it's caused by sunlight scattering from all those trillions and trillions of dust particles which make up the great cosmic cloud.

And although Omar didn't mention it, this 'false dawn' also has an evening counterpart the 'false dusk', the evening zodiacal light, which looks pretty much the same except that it is visible 2 hours after sunset in the west in March when the plane of our Earth's orbit is also almost vertical to the horizon.

Additionally, if you ever see a similar oval shaped glow directly overhead at midnight you would be seeing the zodiacal light's sister phenomenon called the gegenschein or counterglow. And I wonder whether any poet ever wrote about that.

At any rate, remember that September is the month to see the 'false dawn' of Omar Khayyam, the morning zodiacal light, which I admit is very elusive. But once you've found it I think you'll know why it appeared in poetry centuries before it appeared in scientific writings. So get thee outside before dawn during the first two weeks of this month, be sure you're far from city lights and see if you are as inspired as an ancient poet. Keep looking up!

Horkheimer: Almost a thousand years ago the Persian Poet Omar Khayyam wrote about a 'false dawn', which can only be seen in September and which you can see the first two weeks of this September if you're far from city lights because there will be no Moon out to hide its faint glow. Look east about 2 hours before sunrise for a very dim cone shaped patch of light about the brightness of the Milky Way extending from the horizon almost half way up to the zenith. Although Omar couldn't know it his 'false dawn' is actually a humongous cloud of cosmic dust extending from the Sun past Mercury and Venus and slightly beyond Earth. Astronomers call it the zodiacal light. And the first two weeks of September are your best chance to see it this year. See what inspired an ancient poet and maybe inspire yourself. Keep looking up!

To Be Aired : Monday 8/30/2010 through Sunday 9/5/2010

"Celebrate Labor Day The Cosmic Way
With A Giant Triangle Of Stars Overhead"

Horkheimer: Greetings, greetings fellow star gazers. Do you know that every Labor Day weekend three very bright stars, which make a giant triangle shine overhead? Let me show you how to find them this and every Labor Day weekend. Simply go outside between 9 and 10 p.m. your local time any Labor Day weekend and look straight up almost overhead and you will see three extremely bright stars which if we connect with lines make a huge stellar triangle which is traditionally called the Summer Triangle because every year these three stars can be seen rising over the eastern horizon in early evening at the beginning of summer.

But since the stars change their position with each season by the time September rolls around this triangle has changed its position so that in early evening it is almost directly overhead and makes an almost perfect must-see Labor Day tradition. Now each star belongs to a separate constellation. So not only do we also have three wonderful stars we have three equally wonderful constellations. The brightest star is Vega and it belongs to the small constellation Lyra the Harp. The second brightest is Altair in a much larger constellation called Aquila the Eagle. And the dimmest of the three is Deneb which marks the tail of a huge constellation called Cygnus the Swan.

Now if we compare each of these three stars with the star we call our Sun you'll be in for a big surprise. Our Sun is the closest star only 8 1/3 light minutes away which means it takes its light 8 1/3 minutes to reach us, so we see it not as it actually exists now but as it existed 8 1/3 minutes ago. Altair is the closest triangle star and is 17 light years away, which means that it takes its light 17 years to reach us. So we see it not as it exists this Labor Day weekend but as it existed 17 years ago. Wow! Vega is slightly farther, 25 light years away which means that it takes its light 25 years to reach us so we see it as it existed 25 years ago. Wow again! Deneb however is so incredibly far away, 1500 light years, that it takes its light 1500 years to reach us so we see it as it existed 1500 years ago! Super wow!

And talk about size and brightness! Altair is 1 1/2 times the diameter of our almost 1 million mile wide Sun and 9 times brighter. Vega however is 2 1/2 times the diameter of our Sun and is 58 times brighter. But you ain't seen nothing yet because Deneb is a super 116 times as wide as our Sun and 60,000 times brighter! In fact if it were as close as Vega and Altair it would be the brightest star in the night sky. Wowee, wow, wow! So there you have it. Three bright stars forming a giant triangle almost overhead in early evening every Labor Day weekend. So why not make this brilliant threesome a Labor Day Tradition? Happy Labor Day and Keep looking up!

Altair in Aquila the Eagle is only 16 light years away but 1 1/2 times the diameter of and 9 times brighter than our Sun. Vega, the brightest in Lyra the Harp, is 25 light years away and 2 1/2 times as wide as our Sun and 58 times brighter. But Deneb the dimmest in Cygnus the Swan, is dim only because it is 1500 light years away. In fact it is 116 times bigger than our Sun and 60,000 times brighter. Wow! This great summer triangle is overhead every Labor Day weekend. So why not make it a tradition? "Keep looking up!
