The diagrams shown represent spectral lines of hydrogen gas observed in a laboratory and the spectral lines of hydrogen gas observed in the light from a distant star.

Compared to the spectral lines observed in the laboratory, the spectral lines observed in the light from the distant star have shifted toward the

• red end of the spectrum, indicating the star’s movement toward Earth

• red end of the spectrum, indicating the star’s movement away from Earth

• blue end of the spectrum, indicating the star’s movement toward Earth

• blue end of the spectrum, indicating the star’s movement away from Earth
