Planck maps tiny temperature variations (the mottled colours in the strip) in nine frequency ranges overlaid here. These fluctuations correspond to the matter distribution in the early cosmos. Planck needs six months to complete a full sky map. Esa released more detailed data on the square regions.From The BBC:
The European telescope sent far from Earth to study the oldest light in the Universe has returned its first images.
The Planck observatory, launched in May, is surveying radiation that first swept out across space just 380,000 years after the Big Bang.
The light holds details about the age, contents and evolution of the cosmos.
The new images show off Planck's capabilities now that it has been set up, although major science results are not expected for a couple of years.
