aquila
Aquila, the celestial eagle, is one of the three constellations which have bright stars forming the Summer Triangle. A nearly perfectly straight line of three stars symbolizes part of the wings. The center and brightest of these three stars is Altair. The tips of the wings extend further to the southeast and northwest. The head of the eagle stretches off to the southwest.To the ancient Greeks, Aquila was the servant of Zeus who held the god's thunderbolts and performed errands for him. He may also be the great eagle who devours Prometheus' liver as punishment for giving fire to humans. The line of three stars which includes Altair is revered by Indians as the footprints of the god Vishnu. Some Asian traditions see the bright star Vega as the Weaving-Princess star who marries a shephard, the star Altair.
cygnus
Cygnus, the Swan, is also known as the Northern Cross because of its shape. The tail of the swan is marked by the bright star Deneb, Arabic for "tail". Three fainter stars cross the line between Deneb and the head of the swan, Albireo. Cygnus flies southward along the summer Milky Way, and into the Summer Triangle.Deneb is a bright, blue supergiant star, very young as stars go. Albireo, the bill of the swan, is actually two stars which show a spectacular amber and blue contrast. Cygnus is also sprinkled with a variety of nebulae, including the North American Nebula and the Veil Nebula.
The identity of Cygnus is uncertain. He could be Zeus in the guise in which he seduced Leda, the mother of Helen of Troy. In one myth, Cygnus is a friend of Phaethon, the son of Apollo, the sun god. Phaethon fell into the river Eridanus, trying to drive the sun-gods chariot. Cygnus dove repeatedly into the water to search for Phaethon. Out of pity, Zeus turned the boy into a swan.

hercules
Hercules, the great Greek warrior, can be seen kneeling in the sky for northern latitudes throughout the Spring months. Hercules first becomes visible in the east in April, and works his way high across the night sky through October. From the southern hemisphere, he appears low in the north. Four relatively bright stars form what is commonly known as the Keystone. Hercules' arms and legs extend from this central square.By far the most exciting object to see in Hercules is the magnificent globular cluster M13, which is visible in dark night skies even without binoculars or a telescope. This cluster of 300,000 stars appears as a faint fuzzy spot to the naked eye. It is located between the stars which form the western side of the Keystone.
lyra
Lyra, the Lyre, is a type of small harp held in the player's lap. The brightest star in Lyra, Vega, is placed in the handle of the harp. A small parallelogram of four faint stars just to the southeast of Vega outline the harp itself. Lyra is one of three constellations whose brightest stars form the Summer Triangle.
Vega is a very bright star (the fifth brightest in the whole sky) and is very close. Lyra is also home to one of the brightest, loveliest planetary nebulae, the Ring Nebula. It can be viewed with binoculars, although it's distinctive smoke-ring shape cannot.
According to Greek mythology, the lyre was invented by Hermes as a child when he strung a tortoise shell. He traded the lyre to Apollo, who then gave it to his son, Orpheus, a great poet and musician. Some Asian traditions see the bright star Vega as the Weaving-Princess star who marries a shepherd, the star Altair.
The Lyrid meteor shower happens in April each year. The meteors in the Lyrid meteor shower seem to shoot outward from Lyra.

ophiuchus
The constellation Ophiuchus is the Serpent Bearer. This large constellation can be seen in the night sky from June through October. Although most of the stars are dim, Ophiuchus' teapot shape makes it easy to find.
The constellation is a combination of three different figures. Ophiuchus is holding Serpens Caput in his left hand, and Serpens Cauda in his right. He is located south of Hercules and north of Scorpius.
In Greek myth, Ophiuchus represents the god of medicine, Asclepius. Asclepius was the son of Apollo and was taught by Chiron, the Centaur. He learned how to bring people back from the dead, which worried Hades. The god of the underworld asked his brother Zeus to kill the medicine god. Zeus did strike him dead, but then put the figure of Asclepius in the sky to honor him.
There aren't many bright stars in this constellation, but there is a rather unique one. RS Ophiuchi is a type of star called a recurrent nova. These strange objects stay dim for long periods of time, and then suddenly brighten. The brightest star is called Ras Alhague, and is the head of the serpent bearer.
Ophiuchus is full of celestial objects. There are numerous clusters and one nebula in the constellation.
