The light is dying, for one thing, as Earth’s orbit around the sun and tilt on its axis combine to carry us in this hemisphere further away from receiving the sun’s rays most directly.

光线也在是失去活力，首先，由于地球绕着太阳的轨道，由于地球倾斜的轴线与我们所处的北半球相结合，最直接从太阳所接收到的光线，就愈为遥远。

Spherical Aberration — causes light rays passing through a lens (or reflected from a mirror) at different distances from the optical center to come to focus at different points on the axis.

球差-使以不同孔径角穿过透镜(或从镜面上发射)的光线不能聚焦在轴上的同一点。
