Consider the following stellar spectra from the sun and from a supercluster of galaxies. ABSORPTION LINES FROM THE SUN ABSORPTION LINES FROM A SUPERCLUSTER OF GALAXIES BAS11 v = 0.07c, d= 1 billion light years a) Describe the movement of the stars in the supercluster relative to the sun. (b) Suppose the absorption lines on the bottom spectrum had varying thickness. What would this indicate about the stars in the supercluster?
