Hubble's constan is the constant in the equation for hubble's law,           
velocity = (Hubble's constant)(distance). This equation allows an astronomer
to calculate the distance to a galaxy if the red shift (and therefore the 
velocity) is known. The value for hubble's constant is somewhere between 50 and
100 km/sec/megaparsec, apparently the data can be intgerpreted two ways.

On a side note, how is red shift calculated?
