How do astronomers determine the temperature of a star and what methods do they use to make these calculations?

Alright, buckle up honey. Astronomers can determine the temperature of a star by analyzing its spectrum, specifically looking at the intensity of light emitted at different wavelengths. They use something fancy called Wien's law or blackbody radiation to make these calculations. It's like playing detective, but instead of solving crimes, they're decoding the secrets of the universe. Cool, huh?
