We were given a photograph of a number of galaxies. In order to locate a particular galaxy a series of numbers were laid out vertically and a series of letters were laid out horizontally. We were also given a magnifying glass with a built in scale to measure the length of the galaxy in millimeters. This experiment required us to calculate the length of 24 stated galaxies whose positions were given in an alphanumeric number e.g . H6, I8. After locating the particular galaxy we would place the magnifying glass on it and measure the length. We followed the same steps for each galaxy....
