But thanks to spectroscopy, we can do just that.

但是多亏了学，我们可以做到一点。

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

也意味着学成为了一种力量，现在跟我一起说：为了科学。

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

我把半导体粒子学目的，学目的，研究半导体粒子表面的学反应。

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

他们发现的学迹象表明，该星系中蕴藏着两个挤满恒星的云团，其中重氦的元素的含量之低打破了记录。

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

被称为学，是 JWST 科学仪器的一大特色。

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

是的，是学在天文学中的重要性的一个很好的例子。

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

天文学家可以使学来确定遥远的恒星由什么组成。

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

所以莱曼系是由一位使学的科学家提出的。

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

我使仪因为我是学家。

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

答案在学，是物理学的一个分支，在一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.

新建的望远镜将具备多功能性， 犹如一把瑞士军刀，但其主要任务将集中在学研究上。

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

学的神奇之处在我们可以它来观察我们周围或银河系中的东西。

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，在未来的15年内，我们可以开始看到真正的学信息从附近有希望的行星开始，去揭示一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的引力影响来发现它。

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.

它还摄影、电影、剧院照明、医学诊断的 x 射线成像、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.

他着手开发改进的学技术，将来自天体的分离成其组成波长，并进行些波长的测量与分析。

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.

利名为“学”的技术，他们发现从星系边缘发出的，似乎来自非常热的源，而个源富含氦元素但基本上不含重元素。

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， 他在学方面的工作改变了我们对的理解，并为学科学奠定了基础，但他又一次选择在三十年里不分享些结果。
