1. Assume the Deep Field represents the actual distribution of galaxies in this 
portion of the sky. (Note: This is an extremely small slice of the cosmos. As 
more redshifts are observed, our conclusions here most certainly will need to be 
modified.) Look at the  histogram for the redshifts.

a. Can you see possible large scale structure such as clustering? If so, at what 
redshifts? (Look for redshifts where there are lots of galaxies.)
b. Are there voids in this field? If so, at what redshifts? (Look for redshifts 
where there are few or no galaxies.) 

2. There are a number of clearly identifiable galaxy types included in the Deep 
Field image. Your instructor identified at least 5 spirals, 1 barred spiral, and 
more than a dozen ellipticals. There are also 4 (and only 4, look for diffraction 
spikes) dim stars from our Galaxy in the image. Locate at least 10 galaxies and 2 
of the stars and sketch them on grid 1.

3. Label each galaxy sketched with the Hubble type of that galaxy.

4. This is an extremely small slice of the Universe. We could identify a cluster 
if we noted a number of galaxies close together in this 2-D image, each of those 
galaxies having similar cosmological redshifts. Look for a group of galaxies that 
you would classify as a cluster, and sketch 4 or more galaxies belonging to that 
"cluster" in grid 2. Write their redshifts in the box also.

5. The galaxies have noticeably different colors. Do you see any overall pattern 
between the color of the galaxy and its Hubble type? Based on what you know about 
the colors of stars, give a brief description of the types of stars that make up 
the different types of galaxies.

6. Speculate on what astronomers would see if we had even bigger, more powerful 
telescopes and detectors and looked even deeper into space. Explain your answer 
based upon the history of our observations of the structure of the Universe and 
what we have discovered as our instruments and technology have improved.
