星云状的

Anyone with a good pair of binoculars, however, can see this Whirlpool toward the constellation of Canes Venatici. M51 is a spiral galaxy of type Sc and is the dominant member of a whole group of galaxies.

但如果有人的眼睛足够好就可以向Canes Venatici星群眺望看见它。M51是一种Sc形态的螺旋状星云并且是整个星系中的领导成员之一。

Explanation: This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments.

蟹状星云是恒星爆炸后留下的痕迹，是公元1054年所见的超新星爆发的结果，它充满了神密的纤维状细丝结构。

Location of the planetary nebulae in the outskirts of the giant galaxy Messier 87 and in the intergalactic space around the centre of the Virgo Cluster of galaxies.

图中标出了位于巨椭圆星系M87外晕远处的和位于室女座星系团中心的星系间空间中的行星状星云。

The team used FLAMES, the super-efficient spectrograph at ESO's Very Large Telescope at the Paranal Observatory in Chile, to make ultra-precise measurements of a host of planetary nebulae in the outskirts of Messier 87 and in the intergalactic space within the Virgo Cluster of galaxies, to which Messier 87 belongs.

研究团队使用FLAMES——VLT阵列中的超高效摄谱仪，极为精确的测量了M87外缘和室女座星系团星系间空间中的行星状星云。

In this image, the separated tail creates the illusion of a reflection nebula. It appears as a faint bluish haze right of center against a background of stars in the loosely grouped Alpha Persei Moving Cluster.

在该照片里，彗尾产生了一个反射星云的效果：即在背景星空衬托下，该彗尾在照片中间偏右疏散星团的地方出显出淡淡的蓝色云雾状。

NGC 5189 is a planetary nebula with an oriental twist. Similar in appearance to a Chinese dragon, these red and green cosmic fireworks are the last swansong of a dying star.

NGC 5189是个行星状星云，它是一颗恒星垂死前的最后表演，它具有少见的东方神物——中国龙的外形。

Alister Ling published a list of 60 "planetary nebulae visible from the city" in the now-defunct Deep Sky magazine (Summer 1986 issue).

在1986年夏天出版的《深空天体杂志》上阿里斯特·林公布了一张60个的&城市中可见的行星状星云&表。

The detection of extragalactic PNe also allows them to be used as standard candles for extragalactic distance scales, probes of distribution of dark matter, as well as tools to study the dynamic history of galaxy clusters.

另外，银河系外的行星状星云既可以用作测量系外距离的标准烛光，又可以成为侦测暗物质分布的探针，及研究星系团动力学历史的工具。

Planetary nebulae are the spectacular final phase in the life of Sun-like stars, when the star ejects its outer layers into the surrounding space.

行星状星云是像太阳这样的恒星最后的辉煌，当恒星进入生命晚期时，它会把外层大气抛到周围的太空中。

Dr Clowe and his colleagues used a technique called gravitational lensing to detect the mass distribution of the bullet cluster.

克洛博士和他的同事使用一种叫做引力透镜的技术来探测子弹状星云团内物质的分布情况。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
