Cosmic Microwave Background And The Dynamic Side Of The Universe

The Planck collaboration has released data from four years of observation by the European Space Agency (ESA)'s Planck spacecraft. The aim of the Planck mission is to study the Cosmic Microwave Background, the light left over from the Big Bang. The measurements, taken in nine frequency bands, were used to map not only the temperature of the radiation but also its polarization - a property of light like color or direction of propagation - which provides additional information about the very early Universe, around 380,000 years old, and our Galaxy's magnetic field.  read more
