Aries as the Golden Fleece

Not long after King Aeetes got the Golden Fleece, an expedition was formed to take it from him. A man named Jason, heir to the throne, needed to accomplish a dangerous task to boost his self-esteem. As a kid he read countless stories or daring deeds and courageous adventures. However, he was a rather wimpy kid who was picked on even in kindergarten. When he heard about the Golden Fleece, Jason vowed to face all dangers and bring it bravely back to Greece. So he gathered a group of explorers called the Argonauts to go with him (The Argonauts were named after the ship - Argo - that bore them to the fleece. The group included such A-listers as Heracles, Orpheus, Castor and Pollux.  The Argo was also an old constellation covering the southern sky now broken up into 6 modern constellations).

Medea, a woman possessed
After facing Harpies, pointy rocks, and mild seasickness Jason made it to the King Aeetes. Aeetes, of course, didn't want to give the fleece away. It still had that new fleece smell. But the King's daughter Medea, caught under a spell from Aphrodite, stood up for Jason. Medea helped him plow a field with fire-breathing bulls, defeat warriors that grew from dragon's teeth, and put a stalwart dragon to sleep to finally gain the fleece. In fact, Medea did all the work - mixing potions to entrance her enemies. Jason took the fleece and Medea back home with him where they did not live happily ever after. Once Aphrodite's spell wore off, Medea and Jason broke up... Alas, love is so fickle.

More about Orion

Orion is the constellation that conjures the deepest imagination and wonder with just one glance. Something about the placement of the stars ties the entire picture together. Not to mention his 3-star-studded belt. Almost every culture in the ancient world associated these stars with a hunter, giant, or all-around he-man.

He was called by the Irish, Caomai, the armed king.
The Hebrews pictured Orion as Jacob wrestling the angel or the general Joshua.

HINDU LEGEND:
Orion was called Praja-pati who took the form of a stag in pursuit of his own daughter (represented by the star Aldebaran in Taurus). The chase was slowed by the arrow stuck in Praja-pati’s midsection (Orion’s belt). This arrow was shot by the avenging hunter (the star Sirius).

Orion's Belt had its own myths:

  • In Greenland it was Three Seal Hunters Lost at Sea
  • Eskimos called it Three Steps Cut in a Snow Bank
  • To Australians these stars were Three Men Dancing
  • In Africa it was Three Pigs
  • And in the picture to the right, this is a picture of Orion as a blanket that I got in South America.  Notice it's upside down!

And there are sometimes where I look at the stars above and picture a particular rock n' roll icon with a snazzy belt and sparkly rhinestones. Instead of a club, he's holding a microphone. Yes, to me Orion is the Great Elvis in the Sky!  Look at that belt...

LUNAR ECLIPSE on DECEMBER 10

 “Biggest Little” Lunar Eclipse
Live From Reno, Nevada

On December 10, 2011 there was a total lunar eclipse – but nobody in Cincinnati could see it. It was only visible west of the Rocky Mountains so I decided to go to a city with a better angle on the eclipse: Reno, Nevada. As part of my work with the PBS show Star Gazers, the producers of the show (WPBT2 in Miami, Florida) wanted to try something unique. With the help of KNPB (Reno’s PBS station) we made a live webcast of the entire thing (at least until the Moon set).

I and fellow Star Gazer host, Marlene Hidalgo, gave a running commentary, answered questions from viewers and interviewed some special guests during the eclipse from 4:00-7:00am. The weather was perfect for viewing the eclipse from its start to totality when the Moon set behind the mountains west of Reno. I always love that first moment of the eclipse when the dark shadow of the Earth can first be seen on the Moon’s surface. But near before totality, it really turned orange fast. During totality the color wasn’t as dramatic. In fact I thought it to be a very gray eclipse. A lot of the redness increased as the Moon got lower in the sky. It was a great experience to chase this eclipse, and share it with so many people who couldn’t see it. You can find a sped up video of the eclipse at: http://video.wpbt2.org/video/2176957576/

Next up, I plan on traveling out west twice more in 2012 - to observe the Annular Solar Eclipse on May 20 and the Transit of Venus on June 5. Astronomer: Have Telescope, Will Travel.

Orion's Stars

I was always fascinated by the names of the stars. Who named them and what were they thinking about? The most famous star in Orion is, of course, Betelgeuse. People pronounce it in many ways, but I prefer "Beetle-juice." The name is Arabic in origin and means the "Armpit of the Great Central One." Betelgeuse is a red supergiant star nearing the end of its lifetime. When it goes, it will make a huge blast. And it probably will be stinky.

Orion's other armpit (actually his left shoulder) is marked by the deep-blue star Bellatrix. From Greek and Roman origins, Bellatrix means, "Female Warrior" or "Amazon Star." Legends say that women born under this star will be strong and have a gift for language.  Not quite like Bellatrix Lestrange...

Bellatrix "Le Star"
But why does Orion, the meanest, macho-est, man in the sky have a girlie star? He must be in touch with his feminine side...

The brightest star in Orion is actually his left foot, Rigel. Rigel is another Arab-named star meaning, you guessed it, left foot. One of the brightest blue giants, Rigel is a nice contrast to ruddy Betelgeuse.

The three stars in the belt also have Arabic names. From left to right they are Alnitak (the girdle), Alnilam (the string of pearls), and Mintaka (the belt).  "Belt...belt...belt."

Pegasus the Flying Horse Part II

Sometimes I like the names of stars and their origins just as much as the mythologies of entire constellations. So let's take a closer look at four stars in Pegasus the Flying Horse.

The main feature of Pegasus are four stars marking a Great Square in the almost overhead after sunset. This is Pegasus' body and the Arabic names of three of these stars relate to that. The fourth one... well just you wait.

The alpha star in Pegasus is called Markab which means "the saddle" but can be translated as "ship" or "vehicle" - anything to travel upon. Beta is named Scheat, "the horse's shoulder." And gamma is Algenib, "the side" or "the wing." Those seem pretty straightforward and actually correspond to Pegasus' imagined body parts. The Arabic peoples were very literal when it came to naming the stars. The fourth star in the Great Square is a little more complicated.

This star is known today as Alpheratz, "the horse's navel." Technically Alpheratz is located in another famous constellation: Andromeda the Maiden. Andromeda was the daughter of Queen Cassiopeia who was chained to a rock in the ocean as a sacrifice to the dreaded sea monster. So Alpheratz is not only Pegasus' belly but also Andromeda's head. When you see old star maps of the two constellations you can't help but feel sorry for Andromeda. Couldn't they find a little more room for her up there?

I can picture Andromeda discussing the matter with the gods.  Zeus might say, "Well, it's getting pretty crowded up there in the sky - what with all the new constellations."  After a thoughtful pause he continues, "The only empty space is up there by Pegasus' belly.  We'll just have to squeeze you up in there..."

Pegasus the Flying Horse

One of the great fall constellations is Pegasus the Flying horse. He's easy to find in the sky if you're prepared to imagine him flying upside-down. Look for a big square or diamond shape of dim stars almost straight overhead. As an added clue there are very few stars within the square. This is Pegasus' body. His head and mane are to the right from the square.

Pegasus has one of the grossest origin stories I've ever read. He was born during the epic battle between Perseus the Hero and the dreaded Sea Monster. Remember the Sea Monster had just risen from the briny deep to devour poor, helpless Princess Andromeda - when Perseus flew up. And luckily Perseus had just the weapon to fight the horrible beast. Earlier in the day Perseus decapitated Medusa - the snaky-haired gorgon whose look turned all living souls to stone. Perseus closed his eyes and took Medusa's bloody head out of a bag and showed it to the Sea Monster. At first glance the monster turned to stone, cracked of its own weight and fell to the bottom of the sea.

But where did Pegasus come from? I'm getting to it.

During the battle, Medusa's head was still a little juicy. I mean Perseus just killed her that morning after all. When Perseus held out Medusa's head to the Sea Monster some blood dripped out of her neck. When the blood hit the sea water below a magical thing happened. Through some sort of foamy, jello process the Gorgon's blood mixed with the water to form into... Pegasus the Flying Horse. This was a common theme in Greek mythology - when a monster or god bled, something always sprang from it. But it's hard to imagine a lovely winged horse coming from such a gruesome beginning. Those Greeks sure had imaginations!

Cetus the Sea Monster

Our hero Perseus (remember him), was flying through the air, borne on his winged sandals. He was feeling quite proud of himself since he just killed Medusa earlier in the day. Suddenly he hears a scream and looks down to see a young maiden chained to a rock about to be devoured by a sea monster. Perseus thinks, "Man, does it get any better than this?" Not only did he kill Medusa, but now he can save a maiden in distress.

Perseus yells down to Andromeda to close her eyes and he pulls out Medusa's bloody head. He shows the head to the sea monster who instantly turns to stone, cracks of his own monstrous weight, and falls to the bottom of the ocean never to be seen again. Perseus swoops down to unchain Andromeda, and they fly away to live happily ever after.

The constellation Cetus the sea monster can be found basking on the shores of Eridanus, the river constellation. Look for a group of stars that look like a recliner chair to the right of Perseus and below Pegasus. What about Pegasus? Tune in next week...
