In this model Planck data determine the cosmological parameters to high precision. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. It scanned the microwave and submillimetre sky continuously between 12 August 2009 and 23 October 2013, producing deep, high-resolution, all-sky maps in nine frequency bands from 30 to 857 GHz. The European Space Agency's Planck satellite, which was dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. They include Planck data in combination with WMAP polarization, Planck lensing, and high-l CMB experiments, as well as additional non-CMB data as detailed in the main parameter papers.

The polarization data were not used in the 2013 analysis, but with better processing their quality had improved sufficiently to allow their incorporation into the 2015 release. Definitions, conventions and reference are contained in Planck-2013-XVI. Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013, which mapped the anisotropies of the cosmic microwave background (CMB) at microwave and infra-red frequencies, with high sensitivity and small angular resolution.The mission substantially improved upon observations made by the NASA Wilkinson Microwave Anisotropy Probe (WMAP). Compared to the 2015 results, improved measurements of large-scale polarization … 2005 2009 2013 2017 2020 0 500 1K 1.5K.

The temperature and polarization power spectra are consistent with the standard … The high-quality data the mission has produced will continue to be scientifically explored in the years to come. The Planck spectra at high multipoles are extremely well described by the standard spatially-flat six-parameter LCDM cosmology. At a March 21 NASA telephone news conference, scientists from the U.S. team participating in the European Space Agency’s Planck mission to map the cosmic microwave background (CMB) discussed Planck’s first cosmological results, including some surprising news.
