Color-Magnitude Diagram (CMD) of globular cluster M55. Each dot represents a star, its color indicating temperature (red=cool, blue=hot), and position showing brightness and color index (B-V). The diagram reveals distinct stellar populations: main sequence, red giant branch, and blue giants, illustrating stellar evolution and cluster age.
