What is Understanding Standard Candles in Astronomy about?
Standard candles are astronomical objects with known intrinsic luminosities that allow astronomers to calculate distances. There are two primary types of standard candles: 1) Cepheid variable stars, whose period of variability is linked to luminosity, and 2) Type 1A supernovae, which always explode with the same luminosity. Measuring how bright standard candles appear from Earth allows calculation of their distance based on the inverse square law of light diminishing over distance.
