Lab Activities

This lab repeats the experiment done by Edwin Hubble when he first measured the distances of the galaxies. The students tasks are to

  • the relationship between the redshift in spectra of distance galaxies and their distances from Earth; and
  • using the determined redshift distance relationship, estimate the rate of expansion of the universe and to estimate the age of the universe.

The lab is done on a computer using a program which will simulate an observing session at a telescope. The lab write-up contains complete instructions on the use of the software and the calculations required to determine the rate of expansion and the age of the universe.
