πŸ”₯ Development Of Stellar Classification

Annie Jump Cannon developed a system for classifying stars called the Harvard Classification Scheme. It involves categorizing stars into seven main groups based on their temperatures, colors, and brightness. πŸ”₯❄️ The groups are named O, B, A, F, G, K, and M, which help astronomers easily communicate about stars. O-type stars are super hot and blue, while M-type stars are cooler and red. Annie's work made it easier for scientists to understand the life cycle of stars and how they change over millions of years. Her system is still used by astronomers today, and it has helped us identify thousands of stars in our galaxy!
