PIX4588763: 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

PIX4617892: Nebulae of the horse's head and M42 in Orion - Orion deepfield - Dark Nebula of the horse's head (IC434 - B33). Further down, the large Orion nebula (M42) vast star-forming region. Mosaic of images obtained during more than 20 hours of application, using an H - Alpha filter. This large complex of nebulosity is located about 1,500 light years away in Orion. The Orion complex is a gigantic stellar nursery where stars are forming out of the dust and gas in the region. Young energetic stars excite the gas in the region ionizing it and causing it to glow in the hydrogen - alpha and oxygen III emission lines. The brightest star in the photo at upper right at magnitude 1.8 is Alnilam, the middle star of the three distinctive stars in the belt of Orion. At the left is the Flame, NGC 2024, and below it is dark nebula B33, the Horsehead Nebula. Below is a patch of blue reflection nebulosity NGC 1973 - 4 - 5 and bottom is the beautiful Orion Nebula, M 42. Long - exposure image with an Hydrogen alpha filter / Bridgeman Images

The main stars of this constellation are two supergeants, Betelgeuse (red) on the top left and Rigel (blue) on the bottom right. In the center of the constellation are the three stars forming Orion's Belt (or Baldrier) and the dark nebula of the horse's head (IC434 - B33). Further down, the large Orion nebula (M42) vast star-forming region. Wrapping these nebulae, Barnard's loop, a circle-arch nebula that would come from the explosion of a supernova more than two million years ago. The Orion constellation and its nebulae. The two Orion's bright stars are both supergiant stars: Betelgeuse (a red one) and Rigel (blue one). The center of this constellation is the Orion Belt with the Horsehead nebula (IC 434 - B33). Lower, the great Orion nebula, M42, a large star forming region. Also visible on this image, the Barnard's loop, a very faint nebula. This is composite mosaic image assembled from many hours of data including hydrogen alpha filtered exposure / Bridgeman Images

The nebulae NGC 1973 - 5 - 7 are reflection nebula. Most of the blue nebulosity is starlight scattered by dust, while some of the stars are sufficiently hot to excite the wisps of hydrogen that linger here and create a distinctive red glow. To the south of the nebula (at the top of the picture) the Orion nebula, M43 and M42 / Bridgeman Images

PIX4618057: Nebulae NGC 1973 - 1975 - 1977 in Orion - The reflection nebulae NGC 1973 - 75 - 77 in Orion - Reflection nebulae located just north of the Great Orion Nebula. This group of nebulous stars is just half a degree north of the much brighter Orion Nebula and has largely been ignored because of it. The group of stars here appear as a single star to the unaided eye, the northernmost 'star' in the sword of Orion. Most of the blue nebulosity is starlight scattered by dust, while some of the stars are sufficiently hot to excite the wisps of hydrogen that linger here and create a distinctive red glow / Bridgeman Images
