Another type of standard candle is a type of star called a Cepheid variable.───另一种标准烛光是一种叫做造父变星的恒星。

By the late 1980s, a suitable standard candle had been indentified: type Ia supernovae.───到上世纪八十年代末，一个合适的标准烛光出现了，它就是Ia型超新星。

So for decades, astronomers have used it as a "standard candle" in the field of high-energy astrophysics.───因此几十年来，天文学家一直将其视为高能天体物理领域的“标准烛光”使用。

Astrophysicists have long thought of the Crab Nebula as a steady "standard candle" in X-ray wavelengths.───天体物理学家们长久以来一直将蟹状星云的X射线波段视作稳定的“标准烛光”。

Although Cepheids are rare, they provide a very reliable "standard candle" for estimating intergalactic distances.───虽然造父变星数量稀少，它们是估计银河系间距离的一种非常可靠的“标准烛光”。

The original article, When A Standard Candle Flickers, was published on January 12th in the Astrophysical Journal Letters.───原文《当标准烛光闪烁时》，已于1月12日在《天体物理学报》发表。

This is similar to a standard candle appearing fainter at greater distances (left-hand illustration).───图左边就示意：遥远的超新星看起来（比预期的）更暗。

The main results are summarized in the following way: 1. The largest distance D between components is an important parameter which can be employed to classify the "standard candle".

In principle, one can trace that history back in cosmic time by observing a so-called standard candle, a class of astronomical object whose intrinsic luminosity is uniform.
