Such supernovae also function as standard candles whose absolute luminosity is correlated with their evanescent, varying brightness; the Cepheids, whose distances can be calculated, are used to calibrate the absolute luminosity of the supernovae.—Anil Ananthaswamy, Scientific American, 1 Apr. 2025 Yet most measurements of standard candles in the here and now suggest a different value, in the region of 73.2 km/s/Mpc.—Keith Cooper, Space.com, 22 Jan. 2025 Yet astronomers who make the standard candle measurements point their finger at the standard model, or at least some unknown phenomenon that the standard model doesn't predict.—Keith Cooper, Space.com, 22 Jan. 2025 First astronomers identify some type of star with a predictable brightness—a standard candle—that is close enough in our galaxy to directly measure its distance, for example from its apparent motion as Earth orbits the Sun.—Bydaniel Clery, science.org, 13 Aug. 2024 To go farther, astronomers need a brighter standard candle.—Bydaniel Clery, science.org, 13 Aug. 2024 For several years Perlmutter’s SCP collaboration had been banking on type Ia supernovae being standard candles.—Richard Panek, Scientific American, 1 Dec. 2023 For several years Perlmutter's SCP collaboration had been banking on type Ia supernovae being standard candles.—Richard Panek, Scientific American, 14 Nov. 2023 For the local universe, most rely on various standard candles—certain types of supernovae and other astrophysical objects that possess a known, scarcely varying intrinsic brightness, allowing their distances and motions with respect to us to be more easily ascertained.—Jonathan O'Callaghan, Scientific American, 11 May 2023
