What do we know about the conditions in young galaxies that led globular clusters to form? Globular clusters do tend to be composed of old stars, but not entirely. Some of them (e.g., Omega Centauri) have a mix of stars of different ages, implying that there are episodes of star ...
Surrounding the galaxy for thousand and thousand of light years is space.At great distances,however,billions of other galaxies are scattered.These galaxies are of many shapes and sizes.The Milky Way Galaxy is shaped like a spiral(螺旋型)disk.Other galaxies have been found to be shaped like ...
