Name: Rashid Al-SulaitiClass: AST102C40 Astronomy II w/LabThe Shape and Motion of the Milky Way GalaxyPart 1: Globular Clusters1.There are two groups of populations of stars. The first population is randomly distributed and thesecond is centered around a particular point. Based on the picture, we can easily observe that,there are a lot of dots gather at the right ascention 17.5 and Declination -30 degree. Whereasother dots are randomly distributed other regions. However, most of globular clusters arecentered around a particular point.2.As said in the above answer, distribution of globular clusters in the sky appear to be both randomand clustered around one point in the sky. Based on searching online, I know that “the mostmassive of these stars completed their stellar evolution, they expelled gas enriched with heavierelements back into the cluster”. After that “this gas will collide with other gas” and “form morechemically enriched generation of stars”. As we see from the picture, these stars wasconcentrated toward the cluster center. While other less chemically enriched stars are randomlydistributed. However, in general we can see that distribution of globular clusters in the sky appear
