超新星

Two million years ago, just as the Earth's primitive apemen were evolving into big-brained humans, a pair of supernovae explosions occurred near Earth.

200万年前，正当地球上原始猿人在向脑容量更大的人类进化的时候，地球附近的两颗超新星发生了爆炸。

The Cepheids are used to calibrate an even brighter milepost marker that can be used over greater distances, a Type Ia supernova.

造父变星也用于校准可测量极遥远距离的更亮的标准尺——Ia型超新星。

5Ms pulsar in SN1987A, however, we must consider the deformation energy, because the pulsars become oblate ellipsoids in the function of high speed rotation.

在§2.3中我们首先研究了脉冲星自转造成的扁率对其性质的影响，然后给出了超新星1987A脉冲星的一些可观测性质。

Measured at 36 light years across, this young supernova remnant has a rapidly expanding shell of hot gas at few million degrees.

这个年轻的超新星残骸横跨三十六光年，它有一个正在急速膨胀，温度高达数百万度的热气体外壳。

Happened within five hundred light years of us, we would be goners, according to

上，多数超新星离我们的距离超出平常的想象，其亮光在我们看来只不过是非常

It will self-destruct in an explosion called a supernova with the force of 20 billion billion billion megatons of TNT.

它将在一个称为超新星爆炸中自毁，有二百亿个二＋亿个二十亿兆吨黄色TNT炸药的力量。

I wanted to finish that paper on supernovas...

我想完成有关超新星的那篇文章

That unexpected finding was the result of studies of supernovas whose apparent brightness did not match the previous theory.

这个出乎意料的发现是因为发现超新星的亮度和以前的理论不相符。

But how many supernovas have they observed?

但究竟有多少，他们观察到的超新星有？

To find supernovas, astronomers compare images of the same area of the sky taken at different times.

为了发现超新星，天文学家们将不同时间拍下的同一天区的图像作比较。

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
