2019年04月03日:马头星云周围的云气丝-(Wisps Surrounding the Horsehead Nebula)
2019年04月03日:马头星云周围的云气丝-(Wisps Surrounding the Horsehead Nebula)--原图下载{mtitle title="马头星云周围的云气丝"/}Image Credit & Copyright: Mario Zauner说明: 着名的猎户马头星云并不孤单。这张长时间曝光影像显示,中下方这片我们很熟悉的暗色斑块,是一个庞大吸光尘埃和辉光云气複合体的一部份。为了取得这片马头星野的细微结构,一位奥地利的业余天文学家,使用位在后院的望远镜进行了7.5小时的曝光路取像,然后再把氢、氧与硫的辐射分别红、绿和蓝来上色,终而建构出这张精美的影像。所製作出的精采影像,清楚呈现亘古以来被恒星风和古超新星造成和雕塑出的云气丝和尘埃带。其中,火焰星云出现在马头星云的左侧,其左上方则有参宿二,这颗位在猎户腰带中心的亮星。马头星云位在北天的猎户座里,离我们约有1,500光年远。{lamp/}原文:{mtitle title="Wisps Surrounding the Horsehead Nebula"/}Image Credit & Copyright: Mario ZaunerExplanation: The famous Horsehead Nebula in Orion is not alone. A deep exposure shows that thedark familiar shaped indentation,visible just below center, is part of avast complex of absorbingdust andglowing gas. To bring out details of the Horsehead's pasture, an amateur astronomer used a backyard telescope in Austriato accumulate and artistically combine 7.5 hours of images in the light of Hydrogen (red), Oxygen (green), and Sulfur (blue).The resultingspectacular picture details an intricate tapestry of gaseous wisps and dust-laden filaments that were created andsculpted over eons by stellar winds andancient supernovas. The Flame Nebula is visible just to the left of the Horsehead, while the bright star on the upper left is Alnilam, the central star in Orion's Belt.The Horsehead Nebula lies 1,500 light years distant towards the constellation of Orion.

2017年12月01日:北美洲星云与鹈鹕星云-(North America and the Pelican)
2017年12月01日:北美洲星云与鹈鹕星云-(North America and the Pelican)--原图下载{mtitle title="北美洲星云与鹈鹕星云"/}Image Credit &Copyright:Paolo Moroni说明: 美丽地球的拥护者,可能不难认出这些宇宙云的轮廓。在影像左方,边缘镶着黝黑不透光尘埃带的明亮辐射,看似有大陆块的外观,因此这团编录号为NGC 7000的发射星云,拥有北美洲星云的暱称。近在北美洲星云右方的东岸外头,可见到IC 5070,其外观则为它博得鹈鹕星云的称号。这二个距离约1,500光年的明亮星云,同是一个庞大、几乎和猎户座大星云一样邻近的恒星形成区複合体之一部分。在这个距离,这张6度跨幅的广角影像,宽度大约有150光年。这张精心规划的宇宙影像,组合了数幅窄波段影像数据,以突显明亮的电离前沿和原子氢发出的泛红特徵辐射。在幽暗地区巡礼天鹅座时,用双筒望远镜即可在亮星天津四的东北方看到这些星云。{lamp/}原文:{mtitle title="North America and the Pelican"/}Image Credit &Copyright:Paolo MoroniExplanation: Fans of our fair planetmight recognize the outlines of thesecosmic clouds.On the left, bright emission outlined by dark, obscuring dust lanesseems to trace a continental shape,lending the popular nameNorthAmerica Nebula to the emission region cataloged as NGC 7000.To the right, just off the North America Nebula's east coast,is IC 5070, whose profile suggests the PelicanNebula. The two bright nebulae are about 1,500 light-years away,part of the same largeand complex star forming region, almost as nearby as thebetter-known Orion Nebula.At that distance, the 6 degree wide field of view would span150 light-years.This carefulcosmic portrait uses narrow band images to highlight the brightionization fronts and the characteristicred glow from atomic hydrogen gas.Thesenebulae can be seen with binoculars from a dark location. Look northeast of bright starDeneb in the constellation of Cygnus the Swan.

2017年06月04日:猎户座的腰带、火焰和马头-(Orion: Belt, Flame, and Horsehead)
2017年06月04日:猎户座的腰带、火焰和马头-(Orion: Belt, Flame, and Horsehead)--原图下载{mtitle title="猎户座的腰带、火焰和马头"/}Image Credit & Copyright: Rogelio BernalAndreo (Deep Sky Colors)说明: 有什么包围着着名的猎户座腰带星呢?这幅大猎户座 分子 云 複合体的长曝光影像,显示猎户座内从暗星云到星团在内的所有天体,都包覆在大片的气体云气丝里。斜贯影像左侧那三颗最明亮的恒星,是构成着名猎户座腰带的三颗亮星。在参宿一(腰带三星中最下方的亮星)的下方,可见到包覆到在暗棕色尘埃里、散发着激态氢泛红辉光的火焰星云。参宿一的右侧,则可见到緻密尘埃所聚成、或许是天空的星云之中辨认度最高的暗斑状马头星云。这个距离约1,500光年远、编录号为巴纳德33的的暗分子云,之所以能现蹤是因为受到邻近大质量恒星参宿增一的星光之衬托。在接下来的数百万年之中,马头星云的外貌会逐渐改变,最终会被高能星光所摧毁。{lamp/}原文:{mtitle title="Orion: Belt, Flame, and Horsehead"/}Image Credit & Copyright: Rogelio BernalAndreo (Deep Sky Colors)Explanation: What surrounds the famous belt stars of Orion?A deep exposure shows everything from dark nebula to star clusters,all embedded in an extendedpatch ofgaseous wisps in the greaterOrionMolecularCloudComplex. The brightest three stars, appearing diagonally on the left of the featured image are indeed thefamous three stars that make up thebelt of Orion. Just below Alnitak, the lowest of thethree belt stars, is theFlame Nebula, glowing withexcited hydrogen gas and immersed in filaments of dark brown dust. Just to the right of Alnitak lies theHorsehead Nebula, a dark indentation ofdense dust that has perhaps the most recognized nebular shapes on the sky.The dark molecular cloud, roughly 1,500 light years distant, is cataloged as Barnard 33 and is seen primarily because it is backlit by the nearby massive star Sigma Orionis.The Horsehead Nebula will slowly shift its apparent shape over the next few million years and will eventually be destroyed by the high-energy starlight.

2009年09月29日:猎户座星云、尘埃、星星-(Orion in Gas, Dust, and Stars)
2009年09月29日:猎户座星云、尘埃、星星-(Orion in Gas, Dust, and Stars)--原图下载{mtitle title="猎户座星云、尘埃、星星"/}Credit & Copyright: Rogelio Bernal Andreo(Deep Sky Colors)说明: 在猎户座的腰带上远远超过三颗星。从深空的影像中显示,在猎户座分子 云 複合体之中,延展的云气丝藏了无数的黑暗星云到星团的补丁。从最左侧数起的最亮的三颗星也就是着名的猎户座腰带三颗星,参宿一为猎户座腰带中最低的那颗星,在参宿一下方是火焰星云,它是由发出辉光的明亮云气和黝黑的尘埃带所组成。画面中央偏下,也就是位在参宿一右方的马头星云,由緻密的黑暗尘埃组成,应当是天空中最被认可的形状。右上方肉眼可见的猎户座星云 M42,为一高能的炙热气体大锅,新疏散星团诞生于此。而紧邻于左方的是一团很突出的蓝色反射星云,这团云气有时也被称为慢跑人星云(Running Man)。上述影像是连续多天的曝光所结合,该星云星团距离我们约1500光年,影像涵盖75光年。{lamp/}原文:{mtitle title="Orion in Gas, Dust, and Stars"/}Credit & Copyright: Rogelio Bernal Andreo(Deep Sky Colors)Explanation: The constellation of Orion holds much more than three stars in a row. A deep exposure shows everything from dark nebula to star clusters,all imbedded in an extendedpatch ofgaseous wisps in the greaterOrionMolecularCloudComplex. The brightest three stars on the far left are indeed thefamous three stars that make up thebelt of Orion. Just below Alnitak, the lowest of thethree belt stars, is theFlame Nebula, glowing withexcited hydrogen gas and immersed in filaments of dark brown dust. Below the frame center and just to the right ofAlnitak lies theHorsehead Nebula, a dark indentation ofdense dust that has perhaps the most recognized nebular shapes on the sky.On the upper right liesM42, theOrion Nebula,an energetic caldron of tumultuous gas,visible to the unaided eye,that is giving birth to anew open cluster of stars. Immediately to the left ofM42is a prominent bluish reflection nebula sometimes called theRunning Man that houses many bright blue stars. Theabove image, a digitally stitched composite taken over several nights, covers an area with objects that are roughly 1,500light years away and spans about 75 light years.
