What is another word for standard candle?

Pronunciation: [stˈandəd kˈandə͡l] (IPA)

The term "standard candle" is commonly used in astronomy to refer to a luminous object with a known intrinsic brightness, which allows scientists to calculate distances to far-off galaxies or ultimately the size of the observable universe. However, there are alternative expressions for this concept, such as "cosmic yardstick" or "calibrated beacon". In cosmology, the "Hubble constant" is also used as a standard candle, as it relates the speed at which galaxies move away from us with their distance. Other astronomical tools, like supernovae or variable stars, are also employed as standard candles. Regardless of the expression used, standard candles remain an indispensable tool for astronomers to explore the mysteries of the universe.
