漂亮漂亮!我也经常被天空感动,想拍下来,不过。。。难道小桥一直随身带着相机?
看到月食那一张了。。。果然和我们天文课教的一样。。。月全食时月亮是红色的。。。
though the moon is in total eclipse, some light is refracted toward the moon by the earth's atmosphere. as the light passes through the atmosphere, however, the blue end of the spectrum is scattered away more than the red is, so the light that makes it to the moon is more reddish. after reflection from the moon's surface, this light must again pass through the earth's atmosphere and thus the light seen by an observer on the ground is mostly red. this selective scattering also explains why the sun looks red at sunsets and sunrises and why the sky is blue.作者: 小桥流水 时间: 2007-10-21 08:56
我的相机是不离身的,天天都带着,呵呵(万一哪天OB来NZ给我碰到..........汗)其实是因为我今年有学设计,所以经常要留意身边,要随时取材.
