Question

Quizplus · Accepted Answer

Globular star clusters are characterized by their old age and hundreds of thousands of stars densely packed in a relatively small region, typically only about 30 light-years wide. They have no remaining main sequence stars, but millions of white dwarfs. They do not contain brown dwarfs or a mix of young and old stars. Some globular clusters have bright blue main sequence stars, but not thousands of them. Globular star clusters are known to be very old, containing hundreds of thousands of stars, and only about 30 light years wide. They also typically consist of lower-mass, red and yellow stars, rather than the bright blue main sequence stars found in younger clusters.
