The researchers employed the " transit method" often used to find exoplanets.

研究人员采用了经常用来寻找系外行星的" 凌日法" 。

Researchers said the Webb was able to confirm the existence of the exoplanet using the transiting observation method.

研究人员表示，韦伯能够使用凌日观测方法确认这颗系外行星的存在。

Scientists identify planets on a daily basis using a combination of the transit method, the radial-velocity method, direct Imaging or gravitational microlensing.

科学家们几乎每天都在发现它们。主要是通过几种不同的观测方法，包括凌星法、视向速度法、直接观测法或微引力透镜法。

Advanced civilizations there may have already detected us using the transit method, they say, and may now be sending us a message.

他们表示高等文明也许已经用这种方法获知到我们的存在，现在也许正给我们发信息呢。

There are several methods, but the one that will be used very much by James Webb is the transit method.

有多种方法，但 James Webb 最常用的一种方法是中转法。

It's hard. It's hard to find long-period planets with the transit method because you have to be staring at one place for a very long time.

是很困难的。用凌日法很难找到长周期行星，因为你必须盯着一个地方很长时间。

In 1980s, no one knew how to detect a change that small and most astronomers concluded that this so-called “transit method” was “not practical as a primary detection technique”.

在20世纪80年代，没有人知道如何探测到微小的变化，大多数天文学家得出结论，这种所谓的“凌日法”是“不实用的主要探测技术”。
