If a star is being observed from Earth and it's light has shifted towards the blue side of the electromagnetic spectrum it would be...

• Moving towards the Earth
• Moving away from the Earth
• This is a trick question that cannot be answered
• It isn't a star, it is a very large blueberry.

Use the image to identify the motion of the object relative to Earth.  Compare the absorption spectra of the star (top row) to what the star would look like if it were not moving at all relative to Earth (bottom row).

• It is not moving

• It is moving away from Earth (Redshift)

• It is moving towards Earth (Blueshift)

• It is moving towards Earth (Redshift)
