2018年07月02日:从银河盘面到心宿二-(From the Galactic Plane through Antares)
[2018年07月02日:从银河盘面到心宿二-(From the Galactic Plane through Antares)--原图下载](https://apod.nasa.gov/apod/image/1807/MwPastAntares_Andreo_2048.jpg"onMouseOver="if (document.images)document.imagename1.src='image/1807/MwPastAntares_Andreo_1080_annotated.jpg';"onMouseOut="if (document.images)document.imagename1.src='image/1807/MwPastAntares_Andreo_1080.jpg';){mtitle title="从银河盘面到心宿二"/}Image Credit &License: Rogelio BernalAndreo (Deep Sky Colors)说明: 请观赏这幅针对夜空最美丽区域之一所拍摄的精彩影像。在这张主题影像里,我们银河系的盘面斜贯过左下角,色彩缤纷的心宿增四星云及橙黄色的心宿二,则在中右方,而最右缘有夏普勒斯1星云 (Sh2-1)。出现在银河盘面前方的着名的星云,分别是老鹰星云(M16)、三叶星云(M21)及礁湖星云(M8)。影像里的其他星云,还包括烟斗星云和蓝马头星云。一般来说,泛红的区域,是内部有在辐射辉光的激态氢云气。泛蓝的区域,标示出会反射大量年轻亮星蓝光的星际尘埃,而暗棕色区则是较厚的尘埃。影像中可见的大型恒星球,有M4、M9、M19、M28及M80等球状星云。请参考 附随加注影像的各个标示。这幅宽达50度的极宽场影像,涵盖的区域包括左下角的人马座、右上角的巨蛇座、中间的蛇夫座和右缘的天蝎座 。影像光拍摄的时间就超过100小时,还要外加无微不至的事先规画和数位影像处理,才得以完成这幅影像。{lamp/}原文:{mtitle title="From the Galactic Plane through Antares"/}Image Credit &License: Rogelio BernalAndreo (Deep Sky Colors)Explanation: Behold one of the most photogenic regions of the night sky, captured impressively. Featured, the band of our Milky Way Galaxy runs diagonally along the far left, while the colorful Rho Ophiuchus region including the bright orange star Antares is visible just right of center, and the nebula Sharpless 1 (Sh2-1) appears on the far right.Visible in front of the Milk Way band are several famous nebulas including the Eagle Nebula (M16), the Trifid Nebula (M20), and the Lagoon Nebula (M8). Other notable nebulas include the Pipe and Blue Horsehead. In general, red emanates from nebulas glowing in the light of exited hydrogen gas, while blue marks interstellar dust preferentially reflecting the light of bright young stars. Thick dust appears otherwise dark brown. Large balls of stars visible include the globular clusters M4, M9, M19, M28, and M80, each marked on the annotated companion image. This extremely wide field -- about 50 degrees across -- spans the constellations of Sagittarius is on the lower left, Serpens on the upper left, Ophiuchus across the middle, and Scorpius on the right. It took over 100 hours of sky imaging, combined with meticulous planning and digital processing, to create this image.

2017年10月20日: 美丽的三叶星云-(A Beautiful Trifid)
[2017年10月20日: 美丽的三叶星云-(A Beautiful Trifid)--原图下载](https://apod.nasa.gov/apod/image/1710/m020_rooisand_cdk_3500x2500.jpg"onMouseOver="if (document.images)document.imagename1.src='https://apod.nasa.gov/apod/image/1710/m020_rooisand_cdk_1024_withMoon.jpg';"onMouseOut="if (document.images)document.imagename1.src='image/1710/m020_rooisand_cdk_1024.jpg';){mtitle title=" 美丽的三叶星云"/}Image Credit &Copyright: ChamaeleonTeam -Franz Hofmann, Wolfgang Paech说明: 美丽的三叶星云是研究宇宙天体色泽对比的好标的。三叶星云亦称为M20,位在星云群聚的人马座内,离我们约有5,000光年远。三叶星云是我们银河系盘面上的一个恒星形成区,同时拥有三种形态的天文星云,包括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蓝色反射星云、及緻密尘埃云所造成的黝黑剪影状暗星云。在遮光尘埃带的切割下,明亮的发射星云被分割成三片,让它得到三叶星云的令名。在星云中心的左下方,受到新恒星雕塑的云气柱及恒星喷流,曾是哈伯太空望远镜为此区域拍摄的着名特写影像之标的。三叶星云的跨幅约有40光年,在地球的天空中涵盖的区域和月亮相当,不过它过于昏暗,因此肉眼不得见。{lamp/}原文:{mtitle title="A Beautiful Trifid"/}Image Credit &Copyright: ChamaeleonTeam -Franz Hofmann, Wolfgang PaechExplanation: The beautifulTrifid Nebula is acosmic study 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 the Moonin planet Earth's sky.

2015年10月11日:三叶星云的中心区-(In the Center of the Trifid Nebula)
2015年10月11日:三叶星云的中心区-(In the Center of the Trifid Nebula)--原图下载{mtitle title="三叶星云的中心区"/}Image Credit: Subaru Telescope (NAOJ), Hubble Space Telescope, Martin Pugh; Processing: Robert Gendler说明: 位在北天人马座里的三叶星云,是个着名的恒星形成区,在它内部明亮云气和尘埃带纠结成团。在星云中央,三道巨大的尘埃暗带会聚在一起,让这个星云博得三叶星云之名。此外,影像右方有峰峦状的不透光尘埃云,以及散布在星云各处的丝状尘埃。而影像中央的那颗大质量恒星,提供了大部分三裂星云发出辉光的能源。大约是30万年稚龄的三裂星云,又名为M20,是已知最年轻的发射星云之一。三裂星云距离我们大约有9,000光年远,上图所呈现的区域大约是10光年宽。上面这幅组合影像,整合了地面8.2米昴宿望远镜影像的亮度资讯、2.4米哈伯太空望远镜所提供的细部结构、以及Martin Pugh所提供的色彩资料、最后再由Robert Gendler进行影像合成和处理。{lamp/}原文:{mtitle title="In the Center of the Trifid Nebula"/}Image Credit: Subaru Telescope (NAOJ), Hubble Space Telescope, Martin Pugh; Processing: Robert GendlerExplanation: Clouds of glowing gas mingle with dust lanes in the Trifid Nebula, a star forming region toward the constellation of the Archer (Sagittarius). In the center, the three prominentdust lanes that give the Trifid its name all come together.Mountains of opaque dust appear on the right, while other dark filaments of dust are visible threaded throughout the nebula. A single massive starvisible near the center causes much of the Trifid's glow. The Trifid, also known as M20, is only about 300,000 years old, making it among the youngest emission nebulae known. The nebula lies about 9,000 light years away and the partpictured here spans about 10 light years. The above image is a composite with luminance taken from an image by the 8.2-m ground-based Subaru Telescope, detail provided by the 2.4-m orbiting Hubble Space Telescope, color data provided by Martin Pugh and image assembly and processing provided by Robert Gendler.
