The diagram below represents the light spectra given off by the same element as observed under two different conditions. Spectrum A was observed when that element was heated in a laboratory. Spectrum B shows the same element as seen in the light from a distant star.

The light spectrum observed from this distant star shows a

• red shift, which indicates that the star is moving away from Earth

• red shift, which indicates that the star is moving toward the Earth

• blue shift, which indicates that the star is moving away from Earth

• blue shift, which indicates that the star is moving toward Earth
