Figure 1 Figure 1. Use this graph to map the distribution of globular clusters in the galaxy. It is important to note that the Sun is at the center of the graph. Note on the scale of thi the same point in the center of the graph.
Question 1: Place an “X” on the graph at the center of the distribution of globular clusters you plotted. You might do this in pencil so you can examine your result and make adjustments. Question 2: | Now using the graph and the position that you marked for “X”, then determine the right ascension (h : min) and distance in kilo-light-years and put your answers in'the boxes below. Remember again that there is 60 minutes in an hour, not 100! Galactic Center Position [Ty 25 Kly Right Ascension (include units) Distance (incluée units) Question 3: Now that you have a graph of the distribution of globular clusters, use Harlow Shapley’s assumption that the center of the Milky Way galaxy is located at the center of the distribution of globular clusters. Do you think that the Sun is in the center of the Milky Way galaxy? Explain how you know using a complete sentence. Figure 2 A Figure 2. An artist’s impression of the Milky Way galaxy as seen from the outside. 68
Question 4: On the faded image version of Figure 2 below, place an X at the location of the center of the Milky Way galaxy and place dots showing the likely positions for six or seven globular clusters. S I 7 po el Question 5: Write the word “BULGE” on the faded picture above to indicate the location of the galactic bulge. Question 6: In addition to the Milky Way, do you see any other galaxies in the image shown in Figure 27 If so, place a “G” on a couple of them in the faded picture. Question 7: If the super-massive black hole that is located in the center of the Milky Way galaxy (you marked it with an X above) swallowed a large amount of gas, and consequently emitted a burst of light, how long would it take us to observe it from Earth? (Consider the definition of kilo-light-years and use the numerical result from this lab.) 24.994.7 years 69
