Stellar Clusters are very useful laboratories for empirically studying stellar evolution. ... All cluster stars are at the same distance . All cluster stars have the same physical age . ... CM diagram Young Cluster In this case we see the Main Sequence fully represented. The blue dots represent massive stars with short main sequence lifetimes. ... Thus, identifying the most massive star which is still on the main sequence is an effective means of determining the age of a stellar cluster. ...

... This gives us another handle on how distant the stars are. ... Stars differ not only in distance, but also in apparent brightness. ... Ranking stars by brightness . ... The brightness of the star decreases as the square of the distance. ... At what distance would a 100-watt light bulb have the same brightness as the brighter stars? ... So if the distance of the 100-watt light bulb was 5 kilometers, the distance of the brighter stars would be 10,000,000,000,000 kilometers, or about a light-year. ...
