阅读也变得困难起来。一种有害的因素进入了大气，使光明变得幽暗。

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

一种是在附近的宇宙中寻找我们知道其绝对光度的恒。

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

此外，太阳光度的持续增加将对地球造成严重的影响。

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

在 35 亿年后，太阳的亮度将比现在增加 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，太阳的光度将比目的状态增加 10%。

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

当太阳变成一颗时，它的光度会增加2000倍，十分惊人。

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

然而，光度的增不仅仅使太阳明亮。

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

由于太阳亮度的增加，太阳表面的平均温度将上升到 47 摄氏度。

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

凯瑟琳什么也想不起来， 莫里斯的光芒似乎几乎是无情的。

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

太阳的光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.

再加上它们的距离，这就提供了大量关于它们的信息，包括它们的亮度、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，太阳的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.

透过窗帘透出的柔和光芒就是爱本身。

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