How do scientists learn about stars?

Scientists learn about stars through various methods, primarily using telescopes that capture light across different wavelengths, including visible, infrared, and radio. By analyzing the light from stars, they can determine their composition, temperature, age, and distance. Additionally, astrophysical models and simulations help predict stellar behavior and evolution, while space missions provide direct measurements and observations. Combining these techniques allows scientists to build a comprehensive understanding of stellar phenomena.
