Their Lore and Meaning

Aquila, the Eagle
the French Aigle, the German Adler, and the Italian Aquila, next to and westward from the Dolphin, is shown flying toward the east and across p56the Milky Way; its southern stars constituting the now discarded Antinoüs. Early representations added an arrow held in the Eagle's talons; and Hevelius included a bow and arrow in his description; but on the Heis map the Youth is held by Aquila, for the Germans still continue this association in their combined title der Adler mit dem Antinoüs.
Our constellation is supposed to be represented by the bird figured on a Euphratean uranographic stone of about 1200 B.C., and known on the tablets as Idχu Zamama, the Eagle, the Living Eye.
It always was known as Aquila by the Latins, and by their poets as Jovis Ales and Jovis Nutrix, the Bird, and the Nurse, of Jove; Jovis Armigerand Armiger Ales, the Armor-bearing Bird of Jove in this god's conflict with the giants; while Ganymedes Raptrix and Servans Antinoüm are from the old stories that the Eagle carried Ganymede to the heavens and stood in attendance on Jove. Ovid made it Merops, King of Cos, turned into the Eagle of the sky; but others thought it some Aethiopian king like Cepheus, and with the same heavenly reward.
As the eagles often were confounded with the vultures in Greek and Roman ornithology, at least in nomenclature, Aquila also was Vultur volans, the stars β and γ, on either side of α, marking the outstretched wings; this title appearing even as late as Flamsteed's day, and its translation, the Flying Grype, becoming the Old English name, especially with the astrologers, who ascribed to it mighty virtue.
Ἀετός, the Eagle, in a much varied orthography, was used for our constellation by all the Greeks; while poetically it was Διός Ὄρνις, the Bird of Zeus; and Pindar had Ὀινῶν Βασιλεῦς, the King of Birds, which, ornithologically, has come to our day. Later on it was Βάσανος, Βασανισμός andΒασανιστήριον, all kindred titles signifying Torture, referred by Hyde to the story of the eagle which preyed on the liver of Prometheus. Similarly we find Aquila Promethei and Tortor Promethei; but Ideler said that this idea came from a confounding by Scaliger of the Arabic ʽIkāb, Torture, and ʽOḳāb, Eagle.
Dupuis fancifully thought that its name was given when it was near the summer solstice, and that the bird of highest flight was chosen to express the greatest elevation of the sun; and he asserted that the famous three Stymphalian Birds of mythology were represented by Aquila, Cygnus, and Vultur cadens, our Lyra, still located together in the sky; the argument being that these are all paranatellons of Sagittarius, which is the fifth in the line of zodiacal constellations beginning with Leo, the Nemean lion, the object of Hercules' first labor, while the slaying of the birds was the fifth. Appropriately enough, like so much other stellar material, these creatures p57came from Arabia, migrating thence either to the Insula Martis, or to Lake Stymphalis, where Hercules encountered them.
Thompson thinks that the fable, in Greek ornithology, of the eagle attacking the swan, but defeated by it, is symbolical of "Aquila, which rises in the East, immediately after Cygnus, but, setting in the West, goes down a little while before that more northern constellation."
A similar thought was in the ancient mind as to the eagle in opposition to the dolphin and the serpent; their stellar counterparts, Aquila, Delphinus, and Serpens, also being thus relatively situated.
In connection with the story of Ganymede, the eagle appeared on coins of Chalcis, Dardanos, and Ilia; and generally on those of Mallos in Cilicia and of Camarina; while it is shown perched on the Dolphin on coins of Sinope and other towns, chiefly along the Black Sea and Hellespont. One, bearing the prominent stars, was struck in Rome, 94 B.C., by Manius Aquilius Nepos,1 the design being evidently inspired by his name; and a coin of Agrigentum bears Aquila, with Cancer on the reverse, — the one setting as the other rises.
To the Arabians the classical figure became Al ʽOḳāb, probably their Black Eagle, Chilmead citing this as Alhhakhab; while their Al Naṣr al Ṭāïr, the Flying Eagle, was confined to α, β, and γ; although this was contrary to their custom of using only one star for a sky figure. Grotius called the whole Altair and Alcair; Bayer said Alcar and Atair. Al Achsasi, however, mentioned it as Al Ghurāb, the Crow, or Raven, probably a late Arabian name, and the only instance that I have seen of its application to the stars of our Aquila.
Persian titles were Alub, Gherges, and Shahin tara zed, the Star-striking Falcon of Al Naṣr al Dīn, but now divided for β and γ. In the Ilkhanian Tables, as perhaps elsewhere, it was Γύψ πετόμενος, the Flying Vulture; the Turks call it Taushaugjil, their Hunting Eagle; — all these for the three bright stars.
The Hebrews knew it as Neshr, an Eagle, Falcon, or Vulture; and the Chaldee Paraphrase asserted that it was figured on the banners of Dan; but as these tribal symbols properly were for the zodiac, Scorpio usually was ascribed to Dan. This confusion may have originated from the fact, asserted by Sir William Drummond, that in Abraham's day Scorpio was figured as an Eagle. Caesius said that Aquila represented the Eagle of military Rome, or the Eagle of Saint John; but Julius Schiller had already made it Saint Catherine the Martyr; and Erhard Weigel, a p58professor at Jena in the 17th century, started a new set of constellations, based on the heraldry then so much in vogue, among which was the Brandenburg Eagle, made up from Aquila, Antinoüs, and the Dolphin. Hevelius said that the stellar Eagle was a fitting representation of that bird on the Polish and Teutonic coats of arms.
The Chinese have here the Draught Oxen, mentioned in the book of odes entitled She King, compiled 500 years before Christ by K'ung fu tsu, Kung the Philosopher (Confucius), — the passage being rendered by the Reverend Doctor James Legge:
and the three bright stars are their Cowherd, for whom the Magpies' Bridge gives access to the Spinning Damsel, our Lyra, across the River of the Sky, the Milky Way. This story appears in various forms; stars in the Swan sometimes being substituted for those in the Eagle, Lyra becoming the Weaving Sisters.
The Korean version, with more detail, turns the Cowherd into a Prince, and the Spinster into his Bride, both banished to different parts of the sky by the irate father-in‑law, but with the privilege of an annual meeting if they can cross the River. This they accomplish through the friendly aid of the good-natured magpies, who congregate from all parts of the kingdom during the 7th moon, and on its 7th night form the fluttering bridge across which the couple meet, lovers still, although married. When the day is over they return for another year to their respective places of exile, and the bridge breaks up; the birds scattering to their various homes with bare heads, the feathers having been worn off by the trampling feet of the Prince and his retinue. But as all this happens during the birds' molting-time, the bare heads are not to be wondered at; nor, as it is the rainy season, the attendant showers which, if occurring in the morning, the story-tellers attribute to the tears of the couple in the joy of meeting; or if in the evening, to those of sorrow at parting. Should a magpie anywhere be found loitering around home at this time, it is pursued by the children with well-merited ill-treatment for its selfish indifference to its duty. Nor must I forget to mention that the trouble in the royal household originated from the Prince's unfortunate investment of the paternal sapekes in a very promising scheme to tap the Milky Way and divert the fluid to nourish distant stars.
Another version is given by the Reverend Doctor William Elliot Griffis in his Japanese Fairy World, where the Spinning Damsel is the industrious princess Shokujo, separated by the Heavenly River from her herd-boy lover, p59Kinjin. But here the narrator makes Capricorn and the star Wega represent the lovers.
The native Australians knew the whole of Aquila as Totyarguil, one of their mythical personages, who, while bathing, was killed by a kelpie; their stellar Eagle being Sirius.
It was in the stars of our constellation, to the northwest of Altair, that Professor Edward E. Barnard discovered a comet from its trail on a photograph taken at the Lick Observatory on the 12th of October, 1892 — the first ever found by the camera.
Argelander catalogued 82 naked-eye stars in Aquila, including those of Antinoüs; Heis gives 123.

NGC 6751 PLANETARY NEBULA
New Star Cluster Discovered in the Infrared
The new cluster is seen in the center of the red nebula, or star-forming cloud, as the grouping of small blue, yellow, and green stars. The wisps of red are organic molecules within the dust which have been illuminated by nearby star formation. Green indicates the presence of hot hydrogen gas. Blue predominantly reveals older stars. The bright white arc located to the lower left side of the central star cluster shows the area where a massive star is forming.
For years, dense obscuring clouds of dust have blocked the central cluster from optical view. The high density of the stars triggered the GLIMPSE team's automatic cluster-finding computer program to the presence of this cluster. There are still some dust clouds even in the heart of this cluster, as seen in the inset, indicating, that stars are probably still being formed today. With time, these clouds will disappear as more stars form.

Explanation: What do the Owl, the Cat's Eye, the Ghost of Jupiter, and Saturn have in common? They're all planetary nebulae of course, glowing gaseous shrouds shed by dying sun-like stars as they run out of nuclear fuel. Beautiful to look at, the symmetric, planet-like shapes of these cosmic clouds, typically 1,000 times the size of our solar system, evoke their popular names. Flipping through digital pictures made by participants in the Kitt Peak National Observatory Visitor Center'sAdvanced Observing Program, astronomer Adam Block created this delightful animation. Ten different planetary nebula images are presented, each registered on the central star. In order, their catalog designations are NGC 1535, NGC 3242 (Ghost of Jupiter), NGC 6543 (Cat's Eye), NGC 7009 (Saturn Nebula), NGC 2438,NGC 6772, Abell 39, NGC 7139, NGC 6781, and M97 (Owl Nebula). This glorious final phase in the life of a star lasts only about 10,000 years.
