Hoping to learn more about these dim collections of stars, cosmologist Manoj Kaplinghat of the University of California, Irvine, and colleagues measured the mass of 18 of them--the most complete accounting yet.

加州大学尔湾分校的宇宙学家马诺·卡普林哈特及同事希望更多地了解一下这些由恒星构成的暗淡群体，他们测量了其中18个星系的质量，到目前为止这是一套最完善的计算资料。

公元1054年，中国天文史书上记录了一颗非常光亮的客星，我们现在知道这是一颗距离我们6500光年的恒星发生超新星爆炸产生的光芒，爆炸后的残骸现在成为了星云，这星云名为蟹状星云。

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。

For example, Cygnus X-1 of the companion star is probably a black hole.

据猜测，黑洞是死亡恒星的演化物，是在特殊的大质量超巨星坍缩时产生的。

About 7,500 years ago that star exploded in a supernova leaving the Veil Nebula, also known as the Cygnus Loop.

大约7，500年前，一颗恒星发生超新星爆炸，并形成了面纱星云，又被称为天鹅圈。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
