Of course, defined by the path of the Sun through planet Earth's sky, the eclipticplane rides low during July nights in the northern hemisphere's summer skies.
当然,可由此从行星地球的天空中辨认太阳的运行轨迹,黄道平面在北半球夏季七月的天空中的位置很低。

The Earth's axis of rotation is tilted in relation to the eclipticplane, an imaginary surface through Earth's orbit around the sun.
地球的自转轴与黄道面呈一定角度。黄道面是地球公转轨道所在的一个假想平面。

The idea was to take pictures of the night sky along what’s known as the eclipticplane, the band in the sky where most of the other planets orbit, and see if anything moved.
