当绕着恒星运行的行星在恒星前方经过时，会在恒星表面留下微弱的阴影。开普勒正是寻找这样的阴影。
It’s looking for the faint dimming of a star that occurs when an orbiting planet passes in front of it.
开普勒在一眨眼的瞬间，探测到行星绕过恒星，发出一丝细小的阴影。
Kepler finds planets by detecting almost imperceptible 'winks' - the tiny amount of dimming that occurs each time a planet moves across the face of a star.
