If astronomers examine the spectral lines of a distant galaxy and saw that they displayed a blue shift, what would this mean about the motion of the galaxy?

• The galaxy is not moving.

• The galaxy is moving toward Earth.

• The galaxy is moving away from Earth.

• The galaxy is shifting back and forth at 650 Thz, the frequency of blue light.
