这是因为磁场降低了施加在内部气体上的压力，使得太阳黑子比太阳表面的其他部分温度更低。
That's because magnetic fields reduce the pressure exerted on the gases inside of them, making the spots cooler than the rest of the Sun's surface.
当我们的太阳后来温度变得更高时，早期细菌持续清除大气中的二氧化碳和甲烷，使地球的气候不至于变得太热而无法维持生命的存在。

至于动力，它们会利用太阳能或是温度变化从环境中“捡”一点能量。
For power, they "scavenge" energy from the environment, using solar energy or temperature changes.
在一个太阳能发电的环境中记录温度数据看起来再简单不过了，但还是有一些困难需要克服。
It seems simple enough to log temperature data in a solar generation context, but there are a couple hurdles to surmount.
太阳系里所测量到的温度最低的地方是在月球上。
The lowest temperature ever measured in the solar system was on the Moon.
请将温度传感器放在太阳能单元的背后。
举例来说，在我们的太阳系里，对于生命来说，金星的温度太高，而火星的温度则太低。
In our won solar system, for example, Venus is far too hot and Mars is far too cold to support life.
举例来说，在我们的太阳系里，对于生命来说，金星的温度太高，而火星的温度则太低。
In our own solar system, for example, Venus is far too hot and Mars is far too cold to support life.
从两架航天器以不同视角对太阳进行的一项新观测，在很大程度上破解了为什么太阳的大气层——或者说是日冕层——的温度比太阳表面还要高上百万度这个让人困扰不已的谜团。
A new look at the sun using views from two different spacecraft has put a big dent in the nagging mystery of why the sun's atmosphere, or corona, is millions of degrees hotter than its surface.
与白昼和黑夜的时间长度密切相关的是一年中的四季变化，最明显的是夏季和冬季的差别。其原因是太阳的光照和温度在同时发生作用。
Intimately connected with the length of day and night are our seasons, especially summer and winter; for together with the sun's light heat is also called forth.
冰川消融将土地暴露出来，深色的土地就会吸收更多的太阳光，从而导致温度上升得更快。
The more dark areas that are exposed by melting, the more sunlight is absorbed than reflected, causing temperatures to rise faster.
由于太阳光照射角度太小，“勇气号”只好休眠，用它能接收到的微弱太阳能来充电，将自身温度维持在华氏40度。
