There have been many models of China's new plane C919 since it flew into the sky for the first time on May 5 this year.
自从今年5月5日中国新飞机 C919 首次飞上天空以来,已经有了很多它的模型。
The idea was to take pictures of the night sky along what’s known as the ecliptic plane, the band in the sky where most of the other planets orbit, and see if anything moved.
这个想法是沿着所谓的黄道面拍摄夜空,这个地带是空中的这个范围中大部分其他的行星轨道,观察是否有东西移动。
Of course, defined by the path of the Sun through planet Earth's sky, the ecliptic plane 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。
