constellation of ORION

Orion

Orion, the Hunter, is by far the most famous seasonal constellation. No other is more distinct or bright as this northern winter constellation. The famous Orion's Belt makes the hunter easy to find in the night sky.
Orion looks very much like a person. First, you should spot Orion's Belt, which is made of three bright stars in a straight line. One of Orion's legs is represented by the bright star Rigel, one of the brightest stars in the night sky. His two shoulders are made of the stars Bellatrix andBetelgeuse. You can see Betelgeuse's reddish color without a telescope. Other bright stars make up the two arms, one which holds a shield, and another that carries a club.
Many different civilizations saw this constellation in the sky. The most famous stories come from Greek and Roman myths. Orion was a famed hunter, and in one story boasted that no creature could kill him. Hera then sent a scorpion to sting the hunter. Orion smashed the animal with his club, but not before he was poisoned. Both are now on opposite sides of the sky. They cannot be seen at the same time.
A different story tells of the love between Orion and the goddess,Artemis. One day, Orion was swimming out in the sea. Apollo, who very much disliked the man, bet his sister that she couldn't hit the object in the sea with her bow. Artemis didn't realize it was her lover, and shot Orion with an arrow. When she later found out what she had done, she honored the hunter by putting him in the sky.
There are several clusters and nebulae to view in this awesome constellation. The famous Orion Nebula is located in Orion's sword, which hangs from the belt. It is so bright, that even the naked eye can see the fuzzy patch. It looks spectacular even with a small telescope or binoculars. There are numerous other objects in Orion, so scan the constellation with a telescope or binoculars on a clear night! 

constellation of SCORPIUS

Scorpius

More than any other constellation, Scorpius resembles its given name. If you live in the northern hemisphere of the Earth, Scorpius crawls across the southern sky, close to the horizon. But if you live in the southern hemisphere, it passes high in the sky. The bright starAntares marks the heart of the arachnid, and its long curving tail trails to the south. The scorpion once had claws, but they were cut off by Julius Ceasar to form the constellation Libra.
Where stars are concerned, whatever you are looking for, you can probably find it in Scorpius. Antares is an unmistakable, brilliant red supergiant star at the heart of the scorpion. One of the largest, brightest globular clusters in the sky is in Scorpius.
The scorpion holds an infamous place in Greek mythology as the slayer of Orion. One story tells that Orion fled the scorpion by swimming the sea to the island of Delos to see his lover, Artemis.Apollo, seeking to punish Artemis, joined her and challenged her hunting skills, daring her to shoot the black dot that approached in the water. Artemis won the challenge, unknowingly killing her lover by doing so. 

constellation of CYGNUS

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. 

constellation of AQUILA

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. 

Constellation of SAGITTARIUS

Sagittarius

Sagittarius is a centaur, with the torso of a man atop the body of a horse. Unlike the wise and peaceful centaur Chiron (Centaurus), Sagittarius is aiming his giant bow at his neighbor, Scorpius. While this is a very large constellation, its stars are relatively faint and most people easily recognize just the central figure which resembles a teapot with a lid, handle, and spout.
More than a dozen objects reside in Sagittarius, including globular clusters. Recently, astronomers have discovered a small galaxy in Sagittarius that is crashing through the Milky Way.
Exactly who is Sagittarius? The Mediterranean people viewed him as Enkidu, the close friend of Gilgamesh, believed to be represented byOrion. Greek mythology associates Sagittarius with Crotus, the son of the goat-god Pan and Eupheme, the nurse of the Muses. He grew to be a skilled hunter, as well as a man with an artistic soul. The Muses, with whom he was raised, begged Zeus to honor him with a constellation equal to his great talents.
