Student Exploration: Big Bang Theory – Hubble’s Law
  • Student Exploration: Big Bang Theory – Hubble’s Law

  • Exam (elaborations) • 14 pages • 2022
  • Vocabulary: absolute brightness, absorption spectrum, apparent brightness, Big Bang theory, blueshift, Cepheid variable, Doppler shift, Hubble constant, Hubble’s law, luminosity, megaparsec, period, redshift, spectrograph Gizmo Warm-up In 1912, an astronomer named Henrietta Swan Leavitt studied a class of stars called Cepheid variables. These stars change from bright to dim to bright again. Her discoveries led to a method of measuring distances to other galaxies and eventually helped t...

GIZMO Big Bang (1).
  • GIZMO Big Bang (1).

  • Exam (elaborations) • 10 pages • 2022
  • Question: How do Cepheids allow astronomers to measure intergalactic distances? 1. Collect data: Locate and select the yellow Cepheid variable star (A-091) in the lower left section of the Andromeda Galaxy. Click the Collect data button. You will see a graph of the apparent brightness of the star over time. A. How does the star’s apparent brightness change over time? B. Turn on Show time probes. Set the left probe at the first brightness peak, and the right probe at the second brightness...
