2022年08月12日:老鹰星云-(Portrait of the Eagle Nebula)
2022年08月12日:老鹰星云-(Portrait of the Eagle Nebula)--原图下载{mtitle title="老鹰星云"/}Image Credit &Copyright: Charles Bonafilia说明: 仍然包裹在尘埃胎衣云和明亮云气里的M16,又名为老鹰星云,是个年龄约2百万年的年轻星团。这幅採用哈伯色表的此区美丽细緻影像,呈现了因哈伯太空望远镜的恒星形成複合体特写影像,而声名大噪的一些精采宇宙级雕塑。位在影像的中心长达数光年的尘埃云柱,名为象鼻或创生之柱,并在重力挤压下不断形成恒星。此外,来自星团成员星的高能量辐射,侵蚀了云柱顶端的物质,让内藏的新生恒星曝露出来。而从影像中左方的明亮云气脊伸出的一根恒星诞生尘埃柱,则拥有老鹰星云仙女之令名。M16和老鹰星云离我们约有7,000光年远,位在分叉巨蛇座星云群聚的尾部,是用双筒望远镜或小型望远镜轻易可见的天体。上面这幅老鹰星云的望远镜影像,涵盖宽约70光年的区域。{lamp/}原文:{mtitle title="Portrait of the Eagle Nebula"/}Image Credit &Copyright: Charles BonafiliaExplanation: A star cluster around 2 million years young surrounded bynatal clouds of dust and glowing gas,Messier 16 (M16) is alsoknown as The Eagle Nebula.This beautifully detailed imageof the region adopts the colorful Hubble palette and includescosmic sculpturesmade famous in Hubble Space Telescope close-ups of thestarforming complex.Described as elephant trunks orPillars of Creation,dense, dusty columns rising near the center are light-years in length butare gravitationally contracting to form stars.Energetic radiation from the cluster stars erodes material nearthe tips, eventually exposing the embedded new stars.Extending from the ridge of bright emission left of centeris another dusty starforming column known as theFairy of Eagle Nebula.M16 lies about 7,000 light-years away,an easy target for binoculars or small telescopes in anebula rich part of the skytoward the split constellationSerpens Cauda(the tail of the snake).As framed, this telescopic portrait of the Eagle Nebula is about 70light-years across.

2022年08月05日:美丽的三叶星云-(A Beautiful Trifid)
2022年08月05日:美丽的三叶星云-(A Beautiful Trifid)--原图下载{mtitle title="美丽的三叶星云"/}Image Credit &Copyright:Vikas Chander说明: 美丽的三叶星云是研究宇宙天体对比的好标的。亦称为M20的三叶星云,位在星云拥挤的人马座内,离我们约有5,000光年远。三叶星云是位在我们银河系盘面上的恒星形成区之一,同时拥有三种基本形态的天文星云:被氢原子辉光渲染成红色的发射星云、尘埃反射星光所形成的泛蓝反射星云、以及名为暗星云的緻密尘埃云之剪影。此外,在不透光的尘埃带之切割下,明亮的发射星云被分割成不等的三片,为它博得三叶星云的俗名。在发射星云中心的中右上方,有新生恒星发出的喷流和所雕塑出的云气柱,这些因哈伯太空望远镜为此区拍摄的特写影像而声名大噪的天体。宽约40光年、于地球天空的张角与满月相当的三叶星云,是肉眼不得见的昏暗天体。此外,在这片望远镜视野的下右缘,可见到疏散星团M21。{lamp/}原文:{mtitle title="A Beautiful Trifid"/}Image Credit &Copyright:Vikas ChanderExplanation: The beautiful Trifid Nebula is a cosmicstudy in contrasts.Also known as M20, it lies about5,000 light-yearsaway toward the nebula richconstellation Sagittarius.A star forming region in the plane of our galaxy,the Trifid does illustrate three different types ofastronomical nebulae;red emission nebulae dominated bylight from hydrogen atoms,blue reflection nebulae producedby dust reflecting starlight, anddark nebulae wheredense dust clouds appear in silhouette.But the red emission region, roughly separated into threeparts by obscuring dust lanes, is what lends the Trifid itspopular name.Pillars and jets sculpted by newborn stars, above and right ofthe emission nebula's center, appear in famous Hubble Space Telescopeclose-upimages of the region.The Trifid Nebula is about 40 light-years across.Too faint to be seen by the unaided eye, it almost covers thearea of a full moon in planet Earth's sky.Open star cluster M21 just peeks into this telescopic field of view along the bottom right edge of the frame.

2021年09月09日:M16特写-(M16 Close Up)
2021年09月09日:M16特写-(M16 Close Up)--原图下载{mtitle title="M16特写"/}Image Credit &Copyright: Martin Pugh说明: 亦名为老鹰星云的M16,是个稚龄约2百万年,周围还环拱着尘埃和明亮气体胎衣云的星团。这幅美丽细緻、使用哈伯色表上色的此区影像,呈现了因哈伯太空望远镜先前为这个恒星形成区複合体拍摄的特写,而声名大噪的一些宇宙雕塑。在影像的中心附近,有长数光年,正在经历重力塌缩形成恒星,名为象鼻或创生之柱的緻密尘埃柱。而源自此星团成员星的高能辐射,侵蚀了它们柱顶的物质,让内藏的新恒星曝露出来。从影像中左方伸出的明亮脊状结构,是名为老鹰星云仙女的另一根尘埃恒星形成柱。位在星云密布的巨蛇座尾部方向、约7,000光年远处的M16,是使用双筒或小望远镜即可轻易找到的天体。{lamp/}原文:{mtitle title="M16 Close Up"/}Image Credit &Copyright: Martin PughExplanation: A star cluster around 2 million years young surrounded bynatal clouds of dust and glowing gas,M16 is alsoknown as The Eagle Nebula.This beautifully detailed imageof the region adopts the colorful Hubble palette and includescosmic sculpturesmade famous inHubble Space Telescope close-ups of the starforming complex.Described as elephant trunks orPillars of Creation,dense, dusty columns rising near the center are light-years in length butare gravitationally contracting to form stars.Energetic radiation from the cluster stars erodes material nearthe tips, eventually exposing the embedded new stars.Extending from the ridge of bright emission left of centeris another dusty starforming column known as theFairy of Eagle Nebula.M16 lies about 7,000 light-years away,an easy target for binoculars or small telescopes in anebula rich part of the skytoward the split constellationSerpens Cauda(the tail of the snake).

2021年08月12日:美丽的三叶星云-(A Beautiful Trifid)
2021年08月12日:美丽的三叶星云-(A Beautiful Trifid)--原图下载{mtitle title="美丽的三叶星云"/}Image Credit &Copyright: Mike Selby说明: 美丽的三叶星云是很独特的天体。又名为M20的三叶星云,位在星云密布的人马座方向,约5,000光年远之处。三叶星云是银河盘面的恒星形成区之一,同时拥有三种不同形态的天文星云,包括被氢原子辉光染红的发射星云、尘埃反射星光形成的泛蓝反射星云、以及本质为緻密尘埃的剪影状暗星云。 而在不透光尘埃带的切割下,这团明亮的发射星云裂成三片,为它得博得三叶星云的令名。在这团发射星云的中心左下方,可见到新恒星雕塑出的云柱及发出的喷流,它们因出现在哈伯太空望远镜为此区拍摄的多幅特写影像里而声名大噪。在地球的天空中,宽约40光年、张角与满月相近的三叶星云,比人类肉眼所能见的要稍暗一点。{lamp/}原文:{mtitle title="A Beautiful Trifid"/}Image Credit &Copyright: Mike SelbyExplanation: The beautiful Trifid Nebulais a cosmicstudy in contrasts.Also known as M20, it lies about5,000light-years away toward the nebula richconstellation Sagittarius.A star forming region in the plane of our galaxy,the Trifid does illustrate three different types ofastronomical nebulae;red emission nebulae dominated bylight from hydrogen atoms,blue reflection nebulae producedby dust reflecting starlight, anddark nebulae wheredense dust clouds appear in silhouette.But the red emission region roughly separated into threeparts by obscuring dust lanes is what lends the Trifid itspopular name.Pillars and jets sculpted by newborn stars, below and left ofthe emission nebula's center, appear in famous Hubble Space Telescopeclose-upimages of the region.The Trifid Nebula is about 40 light-years across.Just too faint to be seen by the unaided eye, it almost covers thearea of a full moon in planet Earth's sky.

2020年02月13日:史匹哲望远镜的三叶星云-(Spitzer's Trifid)
2020年02月13日:史匹哲望远镜的三叶星云-(Spitzer's Trifid)--原图下载{mtitle title="史匹哲望远镜的三叶星云"/}Image Credit: J. Rho(SSC/Caltech), JPL-Caltech, NASA说明: 亦名为M20的美丽三叶星云,是一个小望远镜即见的天体。 位在星云密布的人马座之内,跨幅约30光年、距离约5,500光年远的三叶星云,是观星者巡天的热门标的之一。就如其名称所示,在可见光影像里,这团星云被黝黑的尘埃带分割成三片。不过,这幅高穿透力的红外光影像,清楚呈现了三叶星云丝缕状的明亮尘埃云和新诞生恒星。这张精采的假色影像,是由史匹哲太空望远镜所拍摄。对这个非常有趣的恒星诞生区,天文学家用红外光影像数据,去数其中通常包裹在胎衣尘埃和气体云里的新诞生和胚胎期恒星。在2003年发射的史匹哲望远镜,一直从尾随地球的绕日轨道上,透过红外光探索宇宙。不过它的科学观测操作,在今年的1月30日正式结束。{lamp/}原文:{mtitle title="Spitzer's Trifid"/}Image Credit: J. Rho(SSC/Caltech), JPL-Caltech, NASAExplanation: The Trifid Nebula,also known as Messier 20, is easy to find with a small telescope.About 30 light-years across and 5,500 light-years distantit's a popular stop for cosmic tourists in thenebula rich constellationSagittarius.As its name suggests,visible lightpictures show the nebula divided intothree parts by dark, obscuring dust lanes.But thispenetrating infrared imagereveals the Trifid's filaments of glowing dust clouds and newborn stars.The spectacular false-color view is courtesy of theSpitzerSpace Telescope.Astronomers have used theinfrared image datato count newborn andembryonicstars which otherwise can lie hidden in thenatal dust and gas clouds of this intriguingstellar nursery.Launched in 2003, Spitzer explored the infrared Universe froman Earth-trailing solar orbit until its science operations werebrought to a close earlier this year,on January 30.
