It is earth's eye; looking into which the beholder measures the depth of his own nature.
它是大地的眸子，观察它的人可以探测到自己天性的深度。
Because photometers can detect tiny decreases in the brightness of a star, the craft will be able to discover planets as small as Earth.
因为探测船上的光度计可以侦测到恒星亮度的微小变化，便可发现和地球一样小的行星。

Even if you start with something (like a bump on a rotating neutron star) that gives off a perfect sine wave signal, it won't stay that way by the time it gets into the data stream.
即使你开始时探测到一个完美的正弦波信号，等到记录它的时候可就是另外一个样子了。
Unmanned probes are not going to reach the stars within this century.

NF3 has no detectable odor, so forced air/exhaust ventilation and ambient air monitoring are recommended where NF3 is stored or used.
NF3没有可以探测到的气味，所以推荐在储存和或使用NF3的地方采用强迫通风/排气通风。
This expansion should improve our ability to study natural lightning as well as triggered lightning and should increase the odds of detecting more gamma-ray bursts from the thunderclouds.
扩充后应可提升我们研究自然及人造闪电的能力，并增加从雷雨云探测到γ线的机会。
If you've ever thought about digging a hole to China, a new Japanese ship might be your best bet.
