Question
1. Find the two largest, most prominent galaxies in the image. List their redshift. Explain why these galaxies appear large compared to the other galaxies in the image with bigger redshifts.
 
2.Find and examine the six falcies at redshift =0.52. Assume that they are all at the same distance. These galaxies differ in their apparent size in the image. What is the most important factor to account for their different appaarent size?
 
3.Voids are wide regions with fewer or no galaxies compared to adjacent regions. list below 5 voids in this direction of space.
 
4. Describe what this tells us about how galxies are distributed in the universe.
