大麦哲伦星云的NGC 2074

转自:http://hubblesite.org/newscenter/archive/releases/2008/31/image/a/


ABOUT THIS IMAGE:In commemoration of NASA's Hubble Space Telescope completing its 100,000th orbit in its 18th year of exploration and discovery, scientists at the Space Telescope Science Institute in Baltimore, Md., have aimed Hubble to take a snapshot of a dazzling region of celestial birth and renewal.

Hubble peered into a small portion of the nebula near the star cluster NGC 2074 (upper, left). The region is a firestorm of raw stellar creation, perhaps triggered by a nearby supernova explosion. It lies about 170,000 light-years away near the Tarantula nebula, one of the most active star-forming regions in our Local Group of galaxies.

The three-dimensional-looking image reveals dramatic ridges and valleys of dust, serpent-head "pillars of creation," and gaseous filaments glowing fiercely under torrential ultraviolet radiation. The region is on the edge of a dark molecular cloud that is an incubator for the birth of new stars.

The high-energy radiation blazing out from clusters of hot young stars already born in NGC 2074 is sculpting the wall of the nebula by slowly eroding it away. Another young cluster may be hidden beneath a circle of brilliant blue gas at center, bottom.

In this approximately 100-light-year-wide fantasy-like landscape, dark towers of dust rise above a glowing wall of gases on the surface of the molecular cloud. The seahorse-shaped pillar at lower, right is approximately 20 light-years long, roughly four times the distance between our Sun and the nearest star, Alpha Centauri.

The region is in the Large Magellanic Cloud (LMC), a satellite of our Milky Way galaxy. It is a fascinating laboratory for observing star-formation regions and their evolution. Dwarf galaxies like the LMC are considered to be the primitive building blocks of larger galaxies.

This representative color image was taken on August 10, 2008, with Hubble's Wide Field Planetary Camera 2. Red shows emission from sulfur atoms, green from glowing hydrogen, and blue from glowing oxygen.

ABOUT THIS IMAGE:Ground-based image of the region surrounding NGC 2074 in the Large Magellanic Cloud. These optical emission-line images were taken on the Curtis Schmidt telescope at Cerro Tololo Inter-American Observatory as part of the Magellanic Cloud Emission Line Survey. The composite image shows emission from oxygen (blue), hydrogen (green), and sulfur (red). The image is 38 arcminutes square.

嘿嘿·~拉玛老师出好图，先收藏了，顺便顶上

Excellent !!! 3Q3Q

好图，顶一个，

下面那图的翻译：
围绕着NGC 2074的背景图像是LMC星系（大麦哲伦星云的简称，下同）。美国托洛洛山美洲际天文台的Curtis 施密特天文望远镜在进行LMC发射线研究时获得了这些图像。这幅合成图显示了三种元素发射谱线的叠加：蓝色的O、绿色的H、红色的S。整个图像的大小是38角分见方（鬼啊，不用光年什么的单位，用望远镜的分辨率来表示！）

为了大家看得懂链接内容，特意翻译了一下。

本文在索引中链接了2次，把第一部分也翻译了吧

本图是纪念哈勃探索生涯18年来绕地球10万圈的图，巴尔的摩的太空望远镜协会的科学家Md.把哈勃瞄向大麦哲伦云中的一片恒星诞生区域。

哈勃聚焦的是大麦哲伦星系中的星云NGC 2074靠近星团区域一角，这里是恒星焰火的诞生区，这或许是附近一颗超新星爆发引发的（超新星激波压缩了星云并促使产生原始恒星——译注）。NGC 2074离我们大约17万光年，靠近著名的蜘蛛星云。蜘蛛星云是大麦哲伦星系中著名的亮星云，一个极为活跃的恒星形成区（我们已知的最大最亮的星云——译注）。

这个区域位于恒星孵化区分子云边缘，尘埃云形成各种生动的三维效果：由尘埃细丝拟形的“创造之柱”的蛇头在被紫外辐射激发的炽热星云前面（清晰显示出来）。
PS：像什么无所谓，我是不认为这像个蛇头的。“创造之柱”是M16星云中著名的恒星诞生区的尘埃图像，很快将被超新星爆发的激波毁灭。——译注

NGC 2074中已经形成的年轻热星的高能辐射持续而缓慢的蚀刻着尘埃墙。另一群热星可能位于中下部明亮的蓝色气团后面。

这个梦幻风景大约100光年宽度——尘埃黑塔在炽热的分子云前面升起。右下区域的黑影像个海马，这部分大约20光年长，4倍于我们太阳和最近的南门二间距离（最近的是比邻星Alpha Centauri C啊，作者连这个都不知道吗？——译注）

这个区域位于我们银河系的伴星系——大麦哲伦云（LMC），这个（星系）是观察恒星诞生、演化的迷人实验室（直译的）。像LMC这样的矮星系被认为是构架大型星系的积木。

本伪彩图是根据哈勃的WFPC2图像于2008.8.10制作的（其实哈勃图像都是用滤光片拍摄的，所以原始图像是黑白的，参看哈勃档案网站——译注），红色表示硫S的辐射，绿色是灼热的氢H发射线，蓝色是炽热的氧O发射光谱。

这个是以前翻译的，大汗……
我也不修改了，记得以前的错误吧。不过后面这个词看得多了，现在我想应该算相当规范的了。
