恒星

This mass loss creates a more or less spherical cloud around the star and eventually uncovers the star's blazing hot core.

质量损失在恒星周围造就了或多或少呈现球形的云团，并最终将恒星闪耀的炽热核心掀开。

At the dimmest part of a Cepheid's cycle, the ionized gas in the outer layers of the star is opaque, and so is heated by the star's radiation, and due to the increased temperature, begins to expand.

在造父变星的一个光变周期内，恒星外层的电离气体是相对不透明的，因此会吸收恒星的辐射而升温，并开始向外膨胀。

Explanation: To seventeenth century astronomers, Omicron Ceti or Mira was known as a wonderful star, a star whose brightness could change dramatically in the course of about 11 months.

说明：对17世纪的天文学家来说，鲸鱼座ο星是一颗奇妙的恒星，这颗恒星的亮度在大约11个月里会发生明显的变化。

To make such swift progress, the planet circles extremely close-in to its star — about 2 percent of the distance from the Earth to the sun, in fact, or 2 million miles (3.4 million kilometers).

该行星必须在特别近的距离上环绕其恒星，才能运行得如此之快。事实上，这颗行星跟其恒星的距离只有地球到太阳距离的百分之二，换句话说，只有两百万英里（340万公里）。

Coping with the vast difference in brightness between planet and star requires a coronagraph in the telescope to physically block out the star or "virtual coronagraph" software to remove starlight from the image.

处理行星与恒星亮度的巨大差别要求在望远镜里装上日冕观测仪以把恒星遮住，或是用"虚拟日冕仪"软件把星光从影像上除掉。

The left over cosmic debris is steadily being consumed by a black hole with a billion times the mass of the Sun which lies at the center of Centaurus A.

这个行星状星云被认为是一颗类似太阳的恒星正处于生命的最后阶段。最近，许多行星状星云被发现也具有这样的光晕，可能是在恒星演变早期由内部抛出的物质形成。

We also try to give a new definition about the AGB stars. We may refer TPAGB stars as homology AGB stars and the second ignition of hydrogen is an appropriate criterion of the HAGB, since after the second ignition of hydrogen, AGB stars have similar properties and structures: a degenerate CO core covered by double thin burning shells.

我们还尝试着给出一个有关AGB星的新的定义，即可以将热脉动AGB星称做相似AGB星，把恒星是否经历氢的第二次点燃看作恒星是否处于相似AGB的判据，因为在氢的第二次点燃之后，AGB星具有相似的性质和结构：一个简并的碳氧核上面覆盖着两层很薄的燃烧壳层。

The satellite, called WISE, is the most sensitive detector of infrared radiation ever sent into orbit and will seek out objects in the dark spaces between stars and planets, dust clouds, asteroids and suns that have cooled down.

这颗叫" WISE "的卫星是目前发射到空中的最敏锐的红外线侦察机，它能够在恒星，行星，星云，小行星，冷却的恒星之间的黑暗空间里寻找物体。

Regardless of size, all stars are thought to emerge in the same basic way: Gravity contracts a giant, diaphanous cloud of gas and dust and eventually ignites a star's nuclear furnace.

不管大小，所有的恒星都被认为是以同样的方式诞生的：引力使得由气体和尘埃构成的半透明状巨大云团发生收缩，最终点燃了恒星的核熔炉。

Is a more than 2000 billion stars, clusters and nebulae composed of thousands of discoid star system, it is about more than 100000 light years in diameter, center thickness is about more than 6000 light years, because ...

是一个由2000多亿颗恒星、数千个星团和星云组成的盘状恒星系统，它的直径约为100000多光年，中心的厚度约为6000多光年，因其。。。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
