Note, you don’t have to look at all of them as there are 1,358 pictures contained on 28 webpages of results (choose some of the pages you pick randomly so your professor doesn’t all see the same galaxies over and over)! Find 3 images that are particularly interesting to you and include the following:
The 3 I picked are IC 335, NGC 7714, ARP 148 you can google them for picture and info. Photo must be cited as instructed
1) The actual picture taken by Hubble properly cited
2) A physical description of the picture (What is the picture of? What is happening in the picture? What redshift is the picture at? How far away is the particular galaxy presently?) To calculate distance see the table at the end of these instructions from Chiasson’s textbook on Astronomy (Table 24.2). It won’t be exact, but just estimate the present distance given the redshift of the three galaxies you choose.

3) Your personal reaction to the galaxy. Keep in mind that each galaxy that you see contains on average 100,000,000,000 stars. Also show each of your three galaxies to another and record their personal reactions.
