英语翻译
The center of our Milky Way Galaxy is located in the constellation of Sagittarius.In visible light the lion's share of stars are hidden behind thick clouds of dust.This obscuring dust becomes increasingly transparent at infrared wavelengths.This 2MASS image,covering a field roughly 10 x 8 degrees (about the area of your fist held out at arm's length) reveals multitudes of otherwise hidden stars,penetrating all the way to the central star cluster of the Galaxy.
This central core,seen in the upper left portion of the enlarged image,is about 25,000 light years away and is thought to harbor a supermassive black hole.The reddening of the stars here and along the Galactic Plane is due to scattering by the dust; it is the same process by which the sun appears to redden as it sets.The densest fields of dust still show up in this mosaic.Also evident are several nebulae to the lower right,including the Cat's Paw Nebula.The 2MASS analysis software has identified and measured the properties of almost 10 million stars in this spectacular field alone.
This panoramic view encompasses the entire sky as seen by Two Micron All-Sky Survey.The measured brightnesses of half a billion stars (points) have been combined into colors representing three distinct wavelengths of infrared light:blue at 1.2 microns,green at 1.6 microns microns,and red at 2.2 microns.
This image is centered on the core of our own Milky Way galaxy,toward the constellation of Sagittarius.The reddish stars seemingly hovering in the middle of the Milky Way's disc -- many of them never observed before -- trace the densest dust clouds in our galaxy.The two faint smudges seen in the lower right quadrant are our neighboring galaxies,the Small and Large Magellanic Clouds.
A GLIMPSE of the Milky Way
In visible light,the bulk of our Milky Way galaxy's stars are eclipsed behind thick clouds of galactic dust and gas.But to the infrared eyes of NASA's Spitzer Space Telescope,distant stars and dust clouds shine with unparalleled clarity and color.
In this panoramic image (center row) from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) project,a plethora of stellar activity in the Milky Way's galactic plane,reaching to the far side of our galaxy,is exposed.This image spans 9 degrees of sky (approximately the width of a fist held out at arm's length).
The red clouds indicate the presence of large organic molecules (mixed with the dust),which have been illuminated by nearby star formation.The patches of black are dense obscuring dust clouds impenetrable by even Spitzer's super-sensitive infrared eyes.Bright arcs of white throughout the image are massive stellar incubators.
With over 160 megapixels,the full detail in this panorama cannot be appreciated without zooming in to various areas of interest (top and bottom rows).Bubbles,or holes,in the red clouds are formed by the powerful outflows from massive groups of forming stars.Wisps of green indicate the presence of hot hydrogen gas.Star clusters can also be seen as the groupings of blue,yellow,and green specks inside some of the red nebulae,or star-forming clouds.In contrast to the plentiful examples of stellar youth in this montage,Spitzer also sees an object called a planetary nebula (top row,middle).Such nebulae are the final gasp of dying stars like our sun,whose outer layers are blown into space,leaving a burnt -out core of a star,called a white dwarf,behind.
Although this panoramic image captures a large range of the galaxy,it represents only 7.5 percent of the primary GLIMPSE survey,which will image most of the star formation regions in our galaxy.

一瞥银河系
在可见光波段,大部分的我们的银河系的恒星黯然失色背后厚厚云层的银河系尘埃和气体.但对红外线的眼中,美国宇航局的斯皮策太空望远镜,遥远的恒星和尘埃云,闪耀着无与伦比的清晰度和色彩.
在这个全景图（中心排）由银河系遗产红外中旬平面测量,非凡（一瞥）项目,过多的恒星活动在银河系的星系平面,以达到远离我们银河系,是暴露无遗.这种形象跨度为9度的天空（约宽度握拳举行于手臂的长度） .
红色云彩表明,存在着很大的有机分子（混合与灰尘） ,其中已照亮附近的恒星形成.补丁的黑色致密模糊尘雾坚不可摧的,甚至斯皮策的超灵敏红外眼睛是雪亮的.光明弧线的白色整个形象都是巨大的恒星孵化器.拥有超过160百万像素,全面,详细,在这个全景不能受到赞赏,没有放大到各个方面的利益（顶部和底部行） .气泡,或破洞,在红色云彩形成了强大的资金外流的庞大群体的形成恒星.能从绿色表明存在热氢气.星簇也可被看作是该集团的蓝色,黄色和绿色的斑点内的一些红色星云,或恒星形成云.相比之下,以丰富的实例恒星青年在这蒙太奇,天文学家还看到了一个物体称为行星星云（第一排,中） .这种星云是最后奄奄一息死亡的恒星类似太阳,其外层是吹上天,留下一具已烧焦的出核心的星型,即所谓的白矮星,落后了.
虽然这个全景图像捕捉大范围的星系,但它仅7.5 ％的小学一瞥调查中,将图像,大部分的恒星形成区域,在我们的银河.
