The 20 pages that link to Henrietta Swan Leavitt, each with the reason it gives.

• RedshiftRelated: Cepheid distances helped relate galaxy redshifts to distances and reveal cosmic expansion.

• Hubble constantRelated: Cepheids made distant-galaxy distances possible in the early expansion measurements.

• Edwin HubbleRelated: Leavitt’s relation let Hubble estimate distances to Cepheids in nearby galaxies.

• Cepheid variableRelated: Her comparison of Cepheid periods and apparent brightness established the key distance relation.

• Andromeda GalaxyRelated: Her relation enabled Hubble to estimate Andromeda’s distance from its Cepheids.

• Hubble's lawRelated: Cepheids helped make the galaxy distances used to establish the relation possible.

• Annie Jump CannonRelated: Leavitt worked alongside Cannon in Harvard’s women-led astronomical computing group.

• AstrophysicsRelated: Her relation made Cepheids reliable distance indicators for mapping the universe.

• Women in astronomyRelated: Her discovery turned observations made at Harvard into a tool for mapping the universe.

• Harvard ComputersRelated: Her photographic measurements enabled a method for estimating distances to stars and galaxies.

• Harlow ShapleyRelated: Her discovery supplied the calibration that made Shapley’s stellar distance estimates possible.

• Harvard College ObservatoryRelated: Her discovery made the observatory’s photographic plates a tool for measuring cosmic distances.

• Period–luminosity relationRelated: Her analysis established the empirical foundation of the relation.

• Stellar pulsationRelated: Her finding turned pulsation periods into a means of comparing intrinsic stellar luminosities.

• Edward Charles PickeringRelated: Leavitt’s Harvard work under Pickering produced a relation that transformed cosmic distance measurement.

• Walter BaadeRelated: Her relation made Cepheids distance indicators, while Baade established that their populations needed separate calibration.

• Classical Cepheid variableRelated: Her work transformed Cepheids from variable stars into tools for measuring cosmic distances.

• Extragalactic astronomyRelated: Her relation enabled distance measurements to nearby galaxies.

• Observational cosmologyRelated: Her relation enabled distance estimates to nearby galaxies.
