But thanks to spectroscopy, we can do just that.

但是多亏了光谱学，我们可以做到点。

It also meant that spectroscopy became a force, say it with me now: for science.

也意味着光谱学成为了种力，现在跟我起说：为了科学。

I was using semiconductor particles for chemistry purposes, for spectroscopic purposes, studying chemical reactions on the surfaces of semiconductor particles.

我把半导体粒子用于化学目，用于光谱学目，研究半导体粒子表面化学反应。

They found spectroscopic signs that the galaxy harbored two star-packed clumps with record-breaking low levels of elements heavier than helium.

他们发现光谱学迹象表明，该星系中蕴藏着两个挤满恒星云团，其中重于氦元素之低打破了记录。

This is known as spectroscopy and is a major feature of JWST's science instruments.

被称为光谱学，是 JWST 科学仪器特色。

Yes, and this is a good example of how important spectroscopy is in astronomy.

是，是光谱学在天文学中重要性个很好例子。

And astronomers can use spectroscopy to determine what distant stars are made of.

天文学家可以使用光谱学来确定遥远恒星由什么组成。

So the Lyman series was developed by one scientist who was using spectroscopy.

所以莱曼系是由位使用光谱学科学家提出。

And I use a spectrograph because I'm a spectroscopist.

我使用光谱仪因为我是光谱学家。

The answer lies in spectroscopy, a branch of physics that revolutionized  astronomy more than a century ago.

答案在于光谱学，是物理学个分支，在个多世纪前彻底改变了天文学。

The newly built telescope would be something of a Swiss army  knife, but primarily would focus on spectroscopy.

新建望远镜将具备多功能性， 犹如把瑞士军刀，但其主要任务将集中在光谱学研究上。

The amazing thing about spectroscopy is that we can use it to look at stuff that's right around us or across the galaxy.

光谱学神奇之处在于我们可以用它来观察我们周围或银河系中东西。

Well, within the next 15 years, we could start seeing real spectroscopic information from promising nearby planets that will reveal just how life-friendly they might be.

好吧，在未来15年内，我们可以开始看到真正光谱学信息从附近有希望行星开始，去揭示个星球有多适合居住。

Also known as the radial velocity or wobble method, Doppler spectroscopy can detect an exoplanet by its gravitational effects on its host star.

多普勒光谱学， 亦称径向速度法或摆动法，通过探测系外行星对其宿主恒星引力影响来发现它。

It is also used in light meters for photography, films, theater lighting, X-ray imaging for medical diagnosis, spectroscopy, electron microscopes, atomic clocks, automatic doors, elevators, and barcode scanners.

它还用于摄影、电影、剧院照明、医学诊断 x 射线成像、光谱学、电子显微镜、原子钟、自动门、电梯和条形码扫描仪。

He set to work developing improved techniques in spectrography, the separation of light coming from celestial objects into its constituent wavelengths, and the measurement and analysis of those wavelengths.

他着手开发改进光谱学技术，将来自天体光分离成其组成波长，并进行些波长测与分析。

Using a technique called spectroscopy, they were able to see that the light shining from the galaxy's edges seemed to come from very hot sources rich in helium but essentially devoid of heavier elements.

利用名为“光谱学”技术，他们发现从星系边缘发出光，似乎来自非常热光源，而个光源富氦元素但基本上不重元素。

In like manner he did work in optics that transformed our understanding of light, and laid the foundation for the science of spectroscopy, and again chose not to share the results for three decades.

同样， 他在光学方面工作改变了我们对光理解，并为光谱学科学奠定了基础，但他又次选择在三十年里不分享些结果。
