is galaxy 1 moving toward or away from you? e...

# Brief Explanations: If the spectral lines of Galaxy 1 are blueshifted (shifted towards the blue - end of the spectrum as shown in the comparison with our galaxy's spectrum), it means the wavelengths are shorter. According to the Doppler effect in physics, when an object is moving towards an observer, the wavelengths of the light it emits are compressed, resulting in a blueshift. Since the spectrum of Galaxy 1 shows a blueshift compared to our galaxy's spectrum, Galaxy 1 is moving towards us. # Answer: Galaxy 1 is moving towards us because its spectrum shows a blueshift, which according to the Doppler effect indicates motion towards the observer.
