Question 16 (5 points) How is Galaxy B moving when compared to the standard? Galaxy B is red-shifted b Galaxy B is moving at the same speed as us Galaxy B is moving towards us d Galaxy B is moving away from us

# Explanation:<br />## Step 1<br />The problem is asking about the movement of Galaxy B in relation to the standard. The standard in this context is the observer's position.<br /><br />## Step 2<br />The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object (like a galaxy) is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.<br /><br />## Step 3<br />The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object (like a galaxy) is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.<br /><br />## Step 4<br />The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object (like a galaxy) is shifted towards the red end of the spectrum.
