In a Doppler red shift, the observed wavelengths of light from distant celestial objects appear closer to the red end of the spectrum than light from similar nearby celestial objects. The explanation for the red shift is that the universe is presently...

• Remaining constant in size.

• Alternating between contracting and expanding.

• Contracting, only.

Which conclusion can be made by comparing the standard spectrum to the spectrum produced from this distant star?

• The star's spectral lines have shifted toward the ultraviolet end of the spectrum and the star is moving toward Earth.

• The star's spectral lines have shifted toward the ultraviolet end of the spectrum and the star is moving away from Earth.

• The star's spectral lines have shifted toward the infared end of the spectrum and the star is moving toward Earth.

• The star's spectral lines have shifted toward the infrared end of the spectrum and the star is moving away from Earth.
