Answer: No, Ur and Uruk are not the same. They were both located in Lower Mesopotamia, but they were separate city-states. Uruk was the larger city-state and was founded around 4500 BC, while Ur, which is located near the Persian Gulf, was constructed around 3800 BC.
A globular cluster is a collection of stars in the form of a sphere that orbits a galactic core. Global clusters are generally tightly bound by gravity, making the stellar density higher toward the center, and giving them their spherical shapes. Globular clusters are usually found in the halo of a galaxy.
The fact that the gravitational pull of a globular cluster is rather weak means that a single supernova explosion can blow the interstellar gas out of a globular cluster. This would mean that the gas left is not dense enough to form new stars. After the first generation, globular clusters cease to form new stars because they lack material due to their deficiency in heavy elements.
