Spectral Classification
Spectral classification is a system used by astronomers to categorize stars based on their light and temperature. It analyzes the spectrum of light a star emits, revealing its color, composition, and temperature. Stars are classified into categories labeled O, B, A, F, G, K, and M, where O is the hottest and bluest, while M is the coolest and reddest. This classification helps scientists understand a star's life cycle, brightness, and chemical makeup, offering insights into the universe's structure and evolution.

Spectral classification is a system used by astronomers to categorize stars based on their color and the spectrum of light they emit. By analyzing the light from a star, scientists can determine its temperature, composition, and age. Stars are grouped into classes denoted by letters (like O, B, A, F, G, K, M), with "O" being the hottest and "M" the coolest. This classification helps astronomers understand the life cycle of stars, how they evolve, and their roles in the universe. Each class reflects specific characteristics that provide insight into a star's nature.
