When a Star or Galaxy Is Moving Away from Us

When a star or galaxy is moving away from us, we observe the Doppler effect by seeing the lines in its spectrum

A) red-shifted (shifted toward the red end of the light spectrum)
B) blue-shifted (shifted toward the blue or violet end of the light spectrum)
C) yellow-shifted (shifted so all the colors become a little bit yellower)
D) become darker and darker (like a blackbody)
E) you can't fool me, the Doppler effect only applies to motions on Earth, not to the motions of the stars and galaxies
