  1. Edwin Hubble

  2. Distance vs. velocity (away from us)for a bunch of galaxies Velocity (kilometers per second) Distance (megaparsecs) NASA StarChild http://starchild.gsfc.nasa.gov/docs/StarChild/questions/redshift.html

  3. Hubble’s Law Velocity (kilometers per second) Distance (megaparsecs) NASA StarChild http://starchild.gsfc.nasa.gov/docs/StarChild/questions/redshift.html

  4. Hubble’s Law (modern data) Freedman et al. (2001), The Astrophysical Journal 553, 47

  5. ≈ Distance ≈ Velocity Type Ia Supernovae (Knop et al. 2003) How faint each object appears (when viewed from Earth) Redshift (amount universe “stretched” since the object’s light was emitted)

  6. Type Ia Supernovae (Riess et al. 2004) How faint each object appears (when viewed from Earth) Redshift (amount universe “stretched” since the object’s light was emitted)
