这种夜空中的辉光，就是所谓的对日照(德文的意思即为"对面的辉光")，只有在非常非常暗的夜空中，才能看到这种很暗的辉光。

The gegenschein is sunlight back-scattered off small interplanetary dust particles.

对日照是日光经由尘埃粒子的反向散射所造成的。

Here a deep exposure of an extremely dark sky overParanal ObservatoryinChileshows the gegenschein so clearly that even a surrounding glow is visible.

位于智利的帕瑞纳天文台夜空非常黑暗，因此对日照非常明显，甚至周围的光辉也看得见。

不。事实上，在非常暗的夜空中，与太阳相隔 180 度的方向可以看到微弱的光辉，称为对日照(德文的意思即为"对面的辉光")。

The gegenschein is sunlight back-scattered off small interplanetarydustparticles.

对日照是日光经由尘埃粒子的反向散射所造成的。

The gegenschein is distinguished from zodiacal light by the high angle of reflection. During the day, a phenomenon similar to the gegenschein called the glory can be seen in reflecting air or clouds opposite the Sun from an airplane.

对日照与黄道光的不同是在於它的散射角度比较高白天时，若是你在飞机中看到西边的云层受到来自东边的阳光照射，使得云层产生光晕，那就是一种与对日照相类似的现象。
