What is Standard Candles in Astronomy about?

Standard candles are astronomical objects with known luminosity used to measure distances to stars and galaxies based on their radiant flux intensity. Cepheid variable stars, which have a predictable relationship between their brightness variation period and luminosity, serve as key standard candles, allowing distances to be calculated up to 13 million light-years with Earth-bound telescopes and further with space-bound telescopes. Other standard candles, such as supernovae, are utilized for measuring dista
