When a star or galaxy is moving away from us, we observe the Doppler effect by seeing the lines in its spectrum Group of answer choices blue-shifted (shifted toward the blue or violet end of the light spectrum) you can’t fool me, the Doppler effect only applies to motions on Earth, not to the motions of the stars and galaxies become darker and darker (like a blackbody) yellow-shifted (shifted so all the colors become a little bit yellower) red-shifted (shifted toward the red end of the light spectrum)
