PIX4588824: Eagle and Fleche Constellations - Aquila and Sagitta constellations - The brightest star of this constellation is Altair. It is one of the brightest stars in the night sky. It is the center of an almost perfect alignment of three stars and is located about 16 years - light from the Sun. Above the small constellation of the Fleche. Aquila (the Eagle) well represents a mythological bird that was the companion of Jupiter. It lies in the northern Milky Way and contans rich fields of stars particularly in the western half and into adjoining Scutum. The brightest star in the constellation is Altair (Arabic for flying eagle), which is at one corner of the Summer Triangle (Altair, Deneb and Vega). Sagitta (the Arrow) is the third smallest constellation in the sky, and although it contains no bright stars, was well known to the ancient Greeks. Its arrow seems directed through Vulpecula and Pegasus towards Andromeda, skirting Cygnus. These constellations are a little north of the celestial equator and can be seen from all inhabited parts of the planet. Best seen in the early evening in Augus / Bridgeman Images

PIX4589136: Whale Constellation - Constellation of Cetus - Also visible, the constellation Belier at the top of the picture. Cetus (the Whale or Sea Monster) is an ancient constellation in the northern sky depicting a whale - like creature basking on the shores of the fabled stream Eridanus, which flows from the celestial equator far into the southern sky. Cetus is extensive but not very distinctive, containing few bright stars. However, some of the stars are exceptionally interesting, particlarly Mira the wonderful, the prototype variable star, whose variability was first noted 400 years ago. The constellation of Aries is visible at the top of the image / Bridgeman Images

PIX4589254: Constellations of the Compsole and the Great Dog - Constellations of Pyxis and Canis Major - Constellation of the Compsole, near the horizon, and constellation of the Great Dog with the brilliant star Sirius. Pyxis, the Mariner's Compasse was originally Pyxis Nauticus and refers to the magnetic compasset. It is a small, insignificant arrangement of faint stars surrounded by much more eyecatching patterns of stars. Pyxis was once part of the very large constellation Argo Navis, the ship Argo, which carried Jason and the Argonauts. Argo Navis is now obsolete, but it was listed in Ptolemy's star catalogue, the Almagest. When the constellation boundaries were defined by the International Astronomical Union in the 1930s it was the only one of Ptolemy's 48 constellations that was not accepted. Instead, it was divided into the four constellations introduced by the French cleric and astronomer Nicolas de Lacaille in the 1750s: Carina, the keel, Puppis the stern, Vela the sails, and Pyxis. La Caille originally called this part of Argo Navis Malus, the Mast, which is rather more appropriate since the ancient Greeks did not use the magnetic compasse, and such compasse are not usually used on a ship's mast. However, alpha Pixidis, is sometimed known by its Arabic name Al Sumut, meaning “” the way””. This word is the origin of azimuth, a directional coordinate on the horizon / Bridgeman Images

PIX4589335: Constellations du Bouvier - Constellation of Bootes - Constellations du Bouvier et de la Couronne Boreale on its left. Booetes (the Herdsman) is an ancient constellation of a figure driving a bear (Ursa major) around the sky, perhaps holding the tethers of the hunting dogs (Canes Venatici) in the adjoining constellation. The brightest star here is Arcturus, the brightest in the northern sky; its name means 'bearkeeper' in ancient Greek. Other star names illuminate the striding figure - - Izar (the second brightest star) means the belt or girdle, and Alkaurops (the easternmost star) is the Greek for staff or crook. The constellation covers 907 square degrees of sky and is the 19th largest. Best seen in the early evening in June / Bridgeman Images
