The Double Star Cluster has the most colorful mix of stars. Stars change color as they age in this sequence: blue, white, yellow, orange, red. They are "born" in clusters, like huge litters of puppies. Also like dogs, those born bigger age faster and have shorter lifespans. Giant stars only live for millions of years, but dwarf stars live for billions. Since our Sun is a medium-sized yellow star, we could say it is like a cocker spaniel, age 5 billion, with 8 billion years more life to live.
