From TFA[0]:

   A new synthesis of astronomical measurements confirms a persistent mismatch 
   that could point to physics beyond current models

Also from TFA:

   Astronomers have sought to measure the expansion rate of the Universe using 
   two fundamentally different approaches. One method relies on measuring 
   distances to stars and galaxies in the nearby Universe. The other uses 
   measurements of the cosmic microwave background to predict what the expansion 
   rate would be today under the standard model of cosmology.
