A scientist will observe redshift in the spectrum of a distant space object when the object is moving away from the scientist. This is due to the Doppler effect, where light from an object moving away is stretched to longer wavelengths, shifting it towards the red end of the spectrum.

when the object is moving toward the scientist
when the object is stationary
