Life of a Star Cluster. Imagine you could watch a star cluster from the time of its birth to an age of 13 billion years. Describe in one or two paragraphs what you would see happening during that time?

The life span of a star is quite as many more than 10 billion years. During these many years it would pass through different stages of its life, from nebula to (perhaps, the current stage) supernova to neutron star or Black Hole.

The stages of the life of star over a span of 13 billion year can be summarized as

the transition stages are

Nebula → Blue star → Blue-white super-giant star → Supernova → Neutron star →Black Hole.
