The telescope will detect the planetary transits by measuring fluctuations in the star's light.

The craft, which is armed with a telescope that can track more than 100,000 stars simultaneously, looks for slight diminutions of light caused by planetary transits.

装备了一架可以同时观测超过10万颗恒星的望远镜，开普勒搜寻着由行星的凌日现象所产生的微弱光线。
