Planck has completed its first "sky scan" which is giving us a completely new map of the sky that shows remnants of cosmic radiation background, basically, the light from the Big Bang.
Launched from Kourou in May 2009, on top of an an Ariane 5, along with Herschel Infrared Observatory, Planck is the first European mission to study the so- called Microwave Cosmic Background, indeed the relic radiation from the Big Bang. Planck data will help astronomers answer one of the most important questions in modern science: How did the universe begin?
This story shows the first sky scan made by Planck with an interview of ESA Planck Project Scientist Jan Tauber.
