Cosmic cold spot is 'defect' in the universe Oct 27, 2007
Since 2001, scientists have been able to examine the CMB with unprecedented clarity using the Microwave Anisotropy Probe, a NASA satellite mapping the background radiation. Using this data, researchers led by Cruz, have now examined one of the larger and more striking of the cold spots, and modelled its possible evolution using statistics and computer simulations.

Still, cosmology detectives have largely built their current view of the early universe's structure, content, and evolution on these temperature maps, especially the all-sky map produced by NASA's Wilkinson Microwave Anisotropy Probe (WMAP). That seems fair enough, since the WMAP results nicely fit other observational evidence from satellites, balloon-borne experiments, and detectors on the ground and with many known properties of the universe we live in today.
