This work will lay the groundwork for the type of analysis astronomers eventually will need to perform in shortlisting any promising rocky Earth-like planets where the signatures of organic chemicals might indicate the presence of life.

这项工作将奠定分析类型的基础，天文学家最终将寄希望于具有岩石表面特征的类地行星上，如果这类行星上发现支持生命的化学成分，则可能表明有生命存在。

Here is a familiar figure – to stargazers – and to Texans like me.

对于天文学家以及像我这样的得克萨斯州人来说，我们可以看到一个熟悉的身影。

The stargazers also observed comets with sparkling tails, and meteors or shooting stars apparently falling from the sky.

天文学家还发现了彗星那闪光的尾巴，和流星的来源——天空。

Making the simultaneous observations required careful planning between teams at the two locations, and is the first time that astronomers have caught a flare by synchronising their observations in this way.

进行这种同步观测需要异地的两个小组之间的详细规划。这也是天文学家们首次通过这样的手段同步观测到闪耀。

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.
