Question

you are an astronomer observing the shift in absorption lines between a laboratory sample and star observation. when you compare the two, you notice the lines of the star are shifted towards the side of the spectrum. this means the star is moving you

Explanation:

When observing the shift in absorption lines, if the lines are shifted towards the blue side of the spectrum (shorter wavelengths), it indicates a blueshift. A blueshift occurs when an object (in this case, the star) is moving towards the observer. This is based on the Doppler effect in astronomy.

Answer:

The lines of the star are shifted towards the blue side of the spectrum. This means the star is moving towards you.
