What is the maximum distance astronomers can measure as a result of Leavitt's work?

  • 1 billion light years

  • 20 million light years

  • 10 million light years

  • 100,000 light years

Answer

Leavitt's work helped astronomers to determine the maximum distance they can measure. She discovered that Cepheid variable stars have a period-luminosity relationship, which means that the period of the pulsations of the star is related to its luminosity. This allows astronomers to use Cepheid variable stars as standard candles to measure the distance to other galaxies.
