Resources for the "Hubble Redshift Distance Relation" lab

• A connection between radial velocity and distance
• How the value of the Hubble constant affects the large-scale structure of the universe
• An on-line exercise involving the Hubble relationship
• The relationship between distance and velocity allows astronomers to estimate distances to very distant galaxies; it is one of the final steps in the "Cosmological Distance Ladder".
  • Step I: The Size of the Earth and Solar System
  • Step II: The distances to nearby stars via parallax
  • Step III: Using the color-magnitude diagram
  • Step IV: Cepheids and the distance to the LMC
  • Step V: Using Cepheids to measure distances to nearby galaxies
  • Step VI: Estimating distances to distant galaxies
