If the sun were just a tiny point of light and Earth had no atmosphere, then day and night would each be exactly 12 hours long on a spring equinox day.
这也使地球在夜间的照片显得颇为壮观，(通过比较照片中不同地点光的亮度就可以)清楚地看到哪里生活的人多。
It also makes for spectacular photographs of the Earth at night, showing clearly where people prefer to live.
最遥远的爆炸光飞向地球时，被宇宙的膨胀拉长而呈红色——一种被称作红移的现象。
As light from the most distant explosions travels toward Earth, it is stretched by the universe's expansion so that it appears red, a phenomenon known as redshift.
这些奇观只能在太空被观测到，因为地球大气层中的水分将这些波长的光统统吸收了。
These wonders can be seen only from space because water in the Earth's atmosphere absorbs.
原始超新星爆炸时的光到达地球需要5000年之久。
Light from the original supernova explosion likely reached Earth over 5, 000 years ago.
当天文学家用这种方法从地球上观测到一颗恒星在另一颗恒星前“走过”时，距地球较近的这颗恒星的重力就如同一个镜头，将较远的那颗恒星的光弯曲并放大。
In this method, when one star passes in front of another, as seen from Earth, the nearer star's gravity ACTS like a lens, bending and magnifying the more distant star's light.
此时，远在地球南边的欧洲中部和中国的北部，人们都有机会看到这种“光秀”。
At these times, people as far south as Central Europe and northern China can see the light show.

Scientists used the mothership of NASA's recycled Deep Impact comet probe to look at light reflected off Earth, the moon and Mars.
地球大气层中的甲烷是由活体生物产生的，而木星或其他气态行星上的甲烷是由光与大气层中其他化学物质相互作用而产生的。
On Earth, atmospheric methane is generated by living organisms, but on Jupiter and other gas giants, methane is produced by light interacting with other chemicals in the atmosphere.
太阳所发出的紫外光是不统一的，所以由于太阳的自转地球所吸收的紫外光的数量也就不同。
The sun's emissions of UV light are not uniform, so as it rotates UV-bright regions move in and out of view of Earth.
