Hubble Deep Field Worksheet

1. Assume the Deep Field represents the actual distribution of galaxies in this portion of the sky. Look at the histogram for the redshifts.
   1. Can you see possible large scale structure such as clustering? If so, at what redshifts? (Look for redshifts where there are lots of galaxies.)

       

       

       

   2. Are there voids in this field? If so, at what redshifts? (Look for redshifts where there are few or no galaxies.)

2. 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.

    

    

    

    

3. 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.
