【另眼系列之江涛与拉玛联手篇】壮观的NGC1275
[img]http://imgsrc.hubblesite.org/hu/db/2008/28/images/a/formats/print.jpg[/img][color=Blue][b]这张由哈勃望远镜拍摄的NGC1275星系照片完美的展现了其丝状结构。在Perseus星系群中心的红色细丝是由较冷的气体在磁场作用下组成并被华氏100万度的炙热气体所包围。细丝是中央巨型黑洞将其能量转移到周围气体这一反馈过程的明显标志。细丝源，冷气体通过射线泡从星系中央区域被运送上升到炙热的星级气体区域。在远处230百万个光年， NGC1275年是其中一最接近的巨型椭圆星系并且位于Perseus星系群中心。
此星系是在7月份you一台先进的三色滤色相机拍摄。[/b][/color]
[color=Magenta]This Hubble Space Telescope image of galaxy NGC 1275 reveals the fine, thread-like filamentary structures in the gas surrounding the galaxy. The red filaments are composed of cool gas being suspended by a magnetic field, and are surrounded by the 100-million-degree Fahrenheit hot gas in the center of the Perseus galaxy cluster.
The filaments are dramatic markers of the feedback process through which energy is transferred from the central massive black hole to the surrounding gas. The filaments originate when cool gas is transported from the center of the galaxy by radio bubbles that rise in the hot interstellar gas.
At a distance of 230 million light-years, NGC 1275 is one of the closest giant elliptical galaxies and lies at the center of the Perseus cluster of galaxies.
The galaxy was photographed in July and August 2006 with the Advanced Camera for Surveys in three color filters.

[color=Blue][b]活跃星系NGC1275年是一个知名的无线电源(Perseus A），也是一个强X-射线源，这是由于一个黑洞位于星系的中心。被称作Perseus星系群的巨兽也位于其中央。结合多波长图像，星系的动力学也更容易揭示。但是细节和结构从X-射线，光学和无线电波长复合起来后的确复合人们的审美观，但还是得喝其中心那些猛烈事件的描述相结合才会显的生动[/b][/color]
[color=Magenta]The active galaxy NGC 1275 is also a well-known radio source (Perseus A) and a strong emitter of X-rays due to the presence of a black hole in the center of the galaxy. The behemoth also lies at the center of the cluster of galaxies known as the Perseus Cluster. By combining multi-wavelength images into a single composite, the dynamics of the galaxy are more easily visible. Detail and structure from x-ray, optical and radio wavelengths combine for an aesthetically pleasing, but nonetheless violent depiction of events going on at the heart of the galaxy.[/color]

FPOM：[url]http://chandra.harvard.edu/photo/2008/perseus/[/url] 又见二位的合力大作！顶一个！ 多谢水兄力顶。。。。 客气什么，应该的！::070821_01.jpg:: ::070821_04.jpg:: 再顶一个！！！！！ 太好了！顶一个！希望二位以后继续合作，多提供一些酷图、美图。
支持楼上哥们!!~~~~~~~
**** 作者被禁止或删除 内容自动屏蔽 **** 呵呵~美图共赏兮~美图共顶兮~ :handshake 合作愉快,我来补充些资料.NGC 1275星系是英仙座星系团中的主要星系，英仙座是由上图中很多可见的星系组成。在可见光中，NGC1275星系显示出两个截然不同星系之间的一个壮观的碰撞。这个星系群也能放射出X射线。上面显示的不寻常的气体纤维是在一种由氢发出的，具有非常特殊颜色的光，这里是人工合成的粉色。可能纤维的形成包含了两个星系碰撞的详细资料，或者二选一，银河系中心黑洞和周围内在星团气体的交互作用. 两位的动作很快啊

The Hubble Space Telescope has found the answer to a long-standing puzzle by seeing the details of giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275.
“哈勃”空间望远镜观察到活动星系NGC1275周围强大磁场塑造的巨大而精巧的细丝细节回答了一个长久以来难题。
These filaments are the only visible-light manifestation of the intricate relationship between the black hole hosted at the centre of the galaxy and the surrounding cluster gas. They provide important clues about how giant black holes affect their surrounding environment.
这些纤维是位于星系中心的黑洞和周围气体团间复杂关系的唯一可见光表现形式。它们提供了关于巨型黑洞是如何影响其周围环境的重要线索。
NGC 1275 is one of the closest giant elliptical galaxies. It is an active galaxy lying at the centre of the Perseus Cluster of galaxies. The supermassive black hole at its core blows bubbles of radio-wave emitting material into the surrounding cluster gas. Its most spectacular feature is the lacy filigree of gaseous filaments reaching out beyond the galaxy into the multi-million degree X-ray emitting gas that fills the cluster.
NGC1275 是最近的巨椭圆星系之一。它是个位于英仙座星系群中心的活动星系。其核心的超大质量黑洞吹出射电泡，将物质射进周围的气体团中。其最壮观的特征是如同蕾丝般的气体丝，一直延伸到星系之外进入充斥在星系团中高达几百万度的X射线发射气体中。

This stunning image of the giant, active galaxy NGC 1275 was taken using the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys in July and August 2006. It provides amazing detail and resolution of fragile filamentary structures, which show up as a reddish lacy structure surrounding the central bright galaxy. These filaments are cool despite being surrounded by gas that is around 55 million °C. They are suspended in a magnetic field which maintains their structure and demonstrates how energy from the supermassive black hole hosted at the centre of the galaxy is transferred to the surrounding gas.
这一漂亮的图片是NASA/ESA“哈勃”空间望远镜的高级巡天相机于2006年7、8月拍摄的巨大的活动星系NGC1275。它提供了围绕在中心明亮星系周围略泛红色的蕾丝结构令人震惊的细节和解析度。这些“纤维”尽管被摄氏5千5百万度的气体包围着还是冷的。它们被悬置在一个磁场中，正是这一磁场保持了它们的结构，并证明来自于星系中心的超大质量黑洞的能量是如何被转移给周围气体的。
By observing the filamentary structure, astronomers were, for the first time, able to estimate the magnetic field’s strength. Using this information they demonstrated how the extragalactic magnetic fields have maintained the structure of the filaments against collapse caused by either gravitational forces or the violence of the surrounding cluster during their 100-million-year lifetime. The entire image is approximately 260 000 light-years across.
通过观察“纤维”结构，天文学家第一次可以估计该磁场的强度。运用这一信息他们论证了河外星系的磁场是如何在这些“纤维”一亿年的生命期里维持其结构不被引力或周围狂暴的星团扯碎。整个图片跨度大约是26万光年。 [img]http://sci.esa.int/science-e-media/img/17/heic0817c_wallpaper.jpg[/img]
