Practice Constellation

The hunter Orion is one of the most easily spotted constellations, especially in winter, and is visible from every inhabited part of the globe. His belt of three bright stars in a line is quite distinctive (and lies nearly on the celestial equator). A sword hanging from his belt at first sight looks like three stars, but the middle one is ill-defined (with binoculars you can tell that it is not a star, but a fuzzy region--as we are now told, a giant cloud of luminous gas, 20,000 times the diameter of our solar system, called the Great Orion Nebula). Orion's right shoulder is Betelgeuse (pronounced roughly "beetle-juice"), a red giant that is one of the largest stars in the sky (capable of being discerned as an actual disk rather than a point of light with large telescopes; if Betelgeuse were placed at the position of our Sun, the Earth and Mars would fall well inside its surface).

Orion the hunter appropriately faces the red eye (star Aldebaran) of the adjacent bull (constellation Taurus); Albrecht Dürer represented him thus. His dog (constellation Canis Major) walks at his lower right, containing the brightest star in the sky (Sirius). Orion's lower left foot (Rigel) is a bright bluish-white star at a vertex of the so-called "Winter Hexagon." The Bull Taurus contains the bright cluster of six or seven naked-eye stars called the Pleiades.
In Egyptian mythology, Orion was the abode of Osiris, the mythical pharoah who invented the arts of agriculture before being slain by his animal-headed brother, Set. Osiris conquered death and, once resurrected, came to reside in Orion (his wife, Isis, dwelling near Sirius). Jewish tradition eventually identified Orion with Nimrod, the "mighty hunter before the Lord" spoken of in early Genesis. To the ancient Syrians, Arabians, and even Ptolemy, Orion was the Giant; to the Chinese Orion was (with Taurus) the White Tiger; to the Vikings Orwandil. (R. H. Allen, pp. 303ff.) Or, from Ireland, a modern tale of how St. Patrick sent him to hunt in the heavens begins thus...

O'Ryan was a man of might
Whin Ireland was a nation,
But poachin' was his heart's delight
And constant occupation....
Charles G. Halpine

More on Orion

Study Question:
Read Walt Whitman's poem, When I Heard the Learn'd Astronomer, and go outside tonight to look up in perfect silence at Orion. Try to find the Pleiades, and the Winter Hexagon.

Astronomy Picture of the Day

Each day a different image or photograph of our fascinating universe
is featured, along with a brief explanation written by a professional astronomer.

Orion: Head to Toe  - clicar para ver mapa
Credit & Copyright: Rogelio Bernal Andreo
Explanation: Cradled in cosmic dust and glowing hydrogen, stellar nurseries in Orion the Hunter lie at the edge of a giant molecular cloud some 1,500 light-years away. Spanning nearly 25 degrees, this breath-taking vista stretches across the well-known constellation from head to toe (left to right).

The Great Orion Nebula, the closest large star forming region, is right of center. To its left are the Horsehead Nebula, M78, and Orion's belt stars. Sliding your cursor over the picture will also find red giant Betelgeuse at the hunter's shoulder, bright blue Rigel at his foot, and the glowing Lambda Orionis (Meissa) nebula at the far left, near Orion's head. Of course, the Orion Nebula and bright stars are easy to see with the unaided eye, but dust clouds and emission from the extensive interstellar gas in this nebula-rich complex, are too faint and much harder to record. In this mosaic of broadband telescopic images, additional image data acquired with a narrow hydrogen alpha filter was used to bring out the pervasive tendrils of energized atomic hydrogen gas and the arc of the giant Barnard's Loop.

Orion: Cabeça aos Pés - clicar mapa ver parágrafo
Credit & Copyright: Andreo Rogelio Bernal

Explicação: Embalada em poeira cósmica e hidrogênio incandescente, berçários estelares de Orion a mentira Hunter na borda de uma nuvem molecular gigante cerca de 1.500 anos-luz de distância. Abrangendo cerca de 25 graus, esta de tirar o fôlego se estende vista em toda a constelação conhecida da cabeça aos pés (da esquerda para direita).

A Grande Nebulosa de Órion, a região mais próxima grande estrela em formação, é de centro-direita. À sua esquerda está a Nebulosa Cabeça de Cavalo, M78, e as estrelas do cinturão Órion . 

Deslizando o cursor sobre a imagem também vai encontrar gigante vermelha Betelgeuse no ombro do caçador, Rigel azul brilhante no seu pé, e os brilhantes Lambda Orionis nebulosa (Meissa) no canto esquerdo, perto da cabeça de Orion.

 Naturalmente, a Nebulosa de Orion e estrelas brilhantes, são fáceis de ver a olho nu, mas as nuvens de poeira e de emissões do gás interestelar extensa neste rico complexo de  nebulosas , são muito fracas e muito mais difícil de gravar. 

Nesse mosaico de imagens telescópicas de banda larga, dados de imagem adicionais adquiridos com um alfa de hidrogénio estreito um filtro foi utilizado para trazer os tentáculos invasivos de gás de hidrogênio atômico e energizado o arco de Loop de Barnard gigante.

TESOUROS DA NEBULOSA M78

A nebulosa M78 fica localizada na direção da constelação de Órion, a apenas 1600 anos-luz de distância, e é conhecida de astrônomos amadores, que podem vê-la através de telescópios menos potentes.

Essa imagem em particular foi a vencedora do concurso “tesouros escondidos 2010”, uma competição fotográfica organizada pelo European Southern Observatory. Para conferir mais fotos da competição acesse esse site. [Nasa]

ESTRELAS DE ANDRÔMEDA

Andrômeda, essa bela galáxia também conhecida como M31, é uma galáxia espiral próxima a Via Láctea, com apenas 2,5 milhões de anos-luz de distância de nós.

Para produzir essa imagem foram usados dados de dois observatórios espaciais diferentes, que usaram ondas além do espectro visível para nós. 

Na foto, você pode ver as estrelas atuais e as que, provavelmente, ainda irão surgir em Andrômeda.

Estrelas futuras? Nós explicamos. 

A poeira vermelha que você vê, fotografada pelo observatório Herschel, juntamente com o gás interestelar que cerca Andrômeda consiste no material necessário para a formação de novas estrelas.

Já os dados coletados pelo observatório XMM-Newton mostram os sistemas de estrelas binários de Andrômeda, que contém estrelas de nêutron e buracos negros, representando o estágio final na “evolução estelar”.

Andrômeda tem, aproximadamente, o dobro do comprimento da Via Láctea, com 200 mil anos-luz de uma ponta a outra. [Nasa]
