A ESPADA DE ÓRION - M42 E M43

[Orion, IRAS]
O familiar inverno constelação de Orion céu ganha um disfarce espectacular no infravermelho, como pode ser visto nesta imagem falsa-cor construído a partir de dados coletados pelo IRAS, o Satélite Astronômico Infravermelho.  

. Esse quadro, que abrange cerca de 30 x 24 graus é um composto de dados em banda IRAS onda centrado em 12 micra, 60 microns, e 100 mícrons. Novas técnicas de processamento têm sido utilizados para melhorar os detalhes fraco e remover os artefatos instrumentais (bandas) visto em imagens anteriores IRAS.  

. As características mais quente, por exemplo, ~ as estrelas são mais brilhantes de 12 mícrons.  Esta emissão é codificado azul.  
  A poeira interestelar é mais fria e brilha mais de 60 mícrons (código verde) e 100 microns (vermelho codificados).
 
. A região brilhante amarelo no canto inferior direito da imagem é a espada de Orion, contendo a Grande Nebulosa de Orion (M42 e M43).  Acima dela para a esquerda é a nebulosidade em torno da estrela Zeta Orionis correia que contém o frequentemente fotografada Nebulosa Cabeça de Cavalo (visível apenas como uma pequena reentrância no lado direito). 

Superior e para a esquerda é M78, a nebulosa de reflexão.  
. A nebulosa Roseta é o objeto mais brilhante perto da margem esquerda da imagem.
 
A maioria das estrelas brilhantes de Orion visualmente não são proeminentes no infravermelho. No entanto, Betelgeuse pode ser facilmente visto no centro superior da imagem como um ponto azul e branco (a cauda fraco é um artefato instrumental).  

. O grande anel para a direita de Betelgeuse é o remanescente de uma supernova, centrado em torno da estrela Lambda Orionis.  Outro mais fraco, e maior, pode ser visto no quadrante inferior esquerdo da imagem.

    IC 1396 A CORES

    IC 1396 a cores

    2011-03-31

    Crédito: Russell Croman.

    Russell Croman obteve esta espectacular imagem do complexo IC 1396 a partir do seu observatório no Texas, Estados Unidos da América (http://www.rc-astro.com/ ). 
     
    Nela são visíveis o aglomerado de estrelas e a respectiva nebulosidade envolvente, sendo de particular destaque a nebulosa "Tromba de Elefante", visível na parte central, em baixo.
     
    Esta nebulosa é um glóbulo escuro de gás e poeira que se encontra em processo de erosão devido à radiação emitida pelas estrelas envolventes. Muitos outros glóbulos são visíveis na imagem, aparecendo como manchas escuras contra o fundo brilhante.
     
    Para a obtenção desta imagem foram usados filtros para captar a luz proveniente de enxofre, hidrogénio e oxigénio.

    Imagem composta pela sobreposição da emissão rádio (a vermelho) e da emissão óptica (a azul) da fonte Fornax A. Esta fonte consiste em dois lóbulos emissores de ondas rádio, cada um com mais de 40 mil milhões de anos-luz de extensão. 
     
    No centro da emissão reside a galáxia elíptica NGC 1316. Esta é uma galáxia peculiar. 
     
    De facto, pensa-se que ela seja o resultado da colisão de duas ou mais galáxias ocorrida há mais de 3 mil milhões de anos atrás. No seu interior julga-se existir um buraco negro super-maciço.

    ENXAME DA "ÁRVORE DE NATAL" - NGC 2264

    As iluminações de Natal deste ano já foram inauguradas, e o mesmo parece acontecer nesta região do espaço. Nesta imagem de larga escala do enxame conhecido, precisamente, como "Enxame da Árvore de Natal", ou NGC 2264, é ainda possível ver duas famosas nebulosas. Na parte central da imagem, em baixo, vê-se a inconfundível nebulosa do "Cone", e na parte de cima, do lado esquerdo, vê-se a nebulosa "Pele de Raposa".
     
    NGC 2264 é um enxame aberto de estrelas embebidas numa nebulosidade difusa, situado a cerca de 2500 anos-luz de distância, com uma idade estimada de 5 milhões de anos.
     
    Este enxame é tão jovem que cerca de metade das suas estrelas ainda têm discos circum-estelares. 
     
    Esta imagem foi obtida através de filtros sensíveis a emissão de hidrogénio, oxigénio e enxofre.

    Explanation: A lesser known sight in the nebula-rich constellation Orion, NGC 2174 can be found with binoculars near the head of the celestial hunter. About 6,400 light-years distant, the glowing cosmic cloud surrounds loose clusters of young stars. Covering an area larger than the full Moon on the sky, this stunning narrow band image adopts a typical color mapping of the atomic emission from NGC 2174. The false-color mapping shows otherwise red hydrogen emission in green hues and emphasizes sulfur emission in red and oxygen in blue. Placing your cursor on the image will reveal an alternative image of the nebula made through broad band filters. The broad band image combines filters in a closer analogy to human vision, dominated by the red glow of hydrogen.

    Explicação:  

    Uma visão menos conhecida da constelação de Órion nebulosa ricas, NGC 2174 pode ser encontrado com binóculos perto da cabeça do caçador celeste.  

    Cerca de 6.400 anos-luz de distância, os clusters do brilhante envolve nuvem cósmica soltas de estrelas jovens. Cobrindo uma área maior que a Lua cheia no céu, esta imagem deslumbrante banda estreita adota um mapeamento de cores típicas da emissão atômica de NGC 2174.  

    O mapeamento de cores falsas mostra emissão de hidrogênio em contrário vermelho em tons de verde e enfatiza emissão de enxofre e oxigênio em vermelho em azul.  

    Colocar o cursor sobre a imagem revela uma imagem alternativa da nebulosa feita através de filtros de banda larga. A imagem de banda larga combina filtros em uma analogia mais próxima à visão humana, dominada pelo brilho vermelho do hidrogênio.

    NGC 7023: The Iris Nebula
    Credit & Copyright: Daniel López, IAC
     
    Explanation: Like delicate cosmic petals, these clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of the constellation Cepheus. Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023, this is not the only nebula in the sky to evoke the imagery of flowers. Still, this beautiful digital image shows off the Iris Nebula's range of colors and symmetries in impressive detail.

    Within the Iris, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the dusty clouds glow with a faint reddish photoluminesence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula may contain complex carbon molecules known as PAHs. As shown here, the bright blue portion of the Iris Nebula is about six light-years across.

    T.TAURI and Hind's Variable Nebula

    T Tauri and Hind's Variable Nebula

    Image Credit & Copyright: Adam Block, Mt. Lemmon SkyCenter, U. Arizona
    Explanation: The yellowish star near center in this remarkable telescopic skyview is T Tauri, prototype of the class of T Tauri variable stars. Nearby it is a dusty yellow cosmic cloud historically known as Hind's Variable Nebula (NGC 1555). Over 400 light-years away, at the edge of a molecular cloud, both star and nebula are seen to vary significantly in brightness but not necessarily at the same time, adding to the mystery of the intriguing region. T Tauri stars are now generally recognized as young (less than a few million years old), sun-like stars still in the early stages of formation. To further complicate the picture, infrared observations indicate that T Tauri itself is part of a multiple system and suggest that the associated Hind's Nebula may also contain a very young stellar object. The naturally colored image spans about 4 light-years at the estimated distance of T Tauri.
