How rapidly is the universe expanding?

Since Edwin Hubble first discovered in 1929 that galaxies are getting 
farther apart over time, allowing scientists to trace the evolution of 
the universe back to an initial Big Bang, astronomers have struggled to 
measure the exact rate of this expansion. In particular, astronomers 
want to determine a number called the Hubble parameter, a measurement of 
how fast the cosmos is expanding as we speak. The Hubble parameter tells 
us the age of the universe, so measuring it was a major goal for many 
astronomers in the latter half of the 20th century.
