• Modern Planck Radiation Satellite
  Planck collected data for the all-sky map from August 2009 to June 2010.
  o
• The satellite is the most sensitive telescope ever designed to study the cosmic microwave background.
  o
• The remnants of radiation from the Big Bang 13.8 billion years ago – Planck’s detectors by microwave radiation to measure the temperature of this light, searching for regions that are slightly warmer or colder than the average.
