　　The new planet is 30 times farther away than any planet discovered by scientists before. It is in the Milky Way (银河) but it's not in our solar (太阳的) .The new planet moves around a star much like our sun , however. Scientists discovered the planet by using a new planet-searching method, called “ transit technique. ” They were able to catch sight of the planet when it moved in front of its star, causing the star's light to dim(变暗) . Scientists compare the method to discovering the shadow of a bee flying in front of a searchlight 200 miles away. “We believe the door has been opened wide to go and discover planets like Earth.”says Sasselov.
