    There are now two Sound of the Big Bang items on this site, the original version produced in 2003 using the data on the cosmic microwave background from NASA's WMAP satellite mission, and a new version produced in 2013 using the data on the cosmic microwave background from the European Space Agency's Planck satellite mission.  The Planck analysis has superior errors and angular resolution and goes three times as high in angular frequency.  Here we provide links to both versions.
