It became difficult to read. A blight entered the atmosphere and dulled its luminosity.

阅读也得困难起来。一种有害因素进入了大气，使得幽暗。

One is to look for stars in the nearby universe whose absolute luminosity we know.

一种是在附近宇宙中寻找我们知道其绝对度恒星。

In addition, the sun's increasing luminosity will cause severe effects on Earth.

此外，太阳度持续增加将对地球造成严重影响。

In 3.5 billion years, the sun's luminosity will have increased by 40% of its present value.

在 35 亿年后，太阳亮度将比现在增加 40%。

Finally in 1 billion years the sun's luminosity will have increased 10% from its current state.

最后，在十亿年后，太阳度将比目前状态增加 10%。

When it turns into a red giant, the Sun will increase its luminosity by an incredible 2000 times.

当太阳成一颗红巨星时，它度会增加2000倍，十分惊人。

That huge increase in luminosity does more than just make the Sun bright, though.

然而，度巨增不仅仅使太阳亮。

Due to the sun's increasing luminosity, the average surface temperature will have increased to 47 degrees celsius.

由于太阳亮度增加，太阳表面平均温度将上升到 47 摄氏度。

Catherine could think of nothing of the kind, and Morris's luminosity seemed almost pitiless.

什么也想不起来， 莫里斯芒似乎几乎是无情。

It's an incredibly slow but inexorable process: the Sun's increased in luminosity by about 40% since it was born.

太阳度自诞生以来已经增加了大约40%。

Together with their distance, this provides a wealth of information about them including their luminosity, size, and temperature.

再加上它们距离，这就提供了大量关于它们信息，包括它们亮度、大小和温度。

In 1.5 billion years, the sun's luminosity will have caused its habitable zone to move outwards further into the solar system.

在 15 亿年后，太阳亮度将使其宜居带进一步向太阳系外移。

That soft luminosity filtering through the curtains was love itself.

透过窗帘透出柔和芒就是爱本身。

And suddenly I started as an idea of bewildering luminosity shot into my brain.

突然间，我脑中闪过一个令人眼花缭乱亮想法。

This awesome tool conveniently tells you information about a star’s temperature, luminosity, color, and more.

这个很棒工具可以方便地告诉您有关恒星温度、 度、颜色等信息。

The drive was dark at first, then acquired luminosity as I became accustomed to the stars.

车道起初是黑暗， 然后随着我习惯了星星而获得了度。

3% of the Sun's luminosity is the most light that Jupiter could hope to spit out.

太阳度 0.3% 是木星希望吐出最大度。

And quasars are the perfect backlight. Their luminosity can be thousands of times that of whole galaxies.

类星体是完美背源。它们亮度可以是整个星系数千倍。

That makes them good standard candles: objects whose intrinsic brightness, whose luminosity, is known.

它们内在亮度是已知。

A lot of a star's physical characteristics are related: its luminosity depends on its size and temperature.

它亮度取决于它大小和温度。
