Chapter 19 Notes Stars Stars are bright balls of gas that are trillions
... i. While many stars become white dwarves as they get older, very massive stars can become strange objects like pulsars, supernovas, black holes and neutron stars. ii. Supernovas 1. Massive stars use their hydrogen much faster than stars like the sun do. 2. At the end of their lives they may explode ...

Thus, assuming the clusters are distributed uniformly around the galaxy, he measured the 3D distribution of clusters (using Cepheid variables) and then assumed that the center of that distribution was where the center of the galax ...
