Planck Science Team Home

 

The 2015 release to the public of Planck data and scientific results is staged as follows:

- The data products and scientific results have been presented in December 2014 at public conferences in Ferrara and Paris. Most presentations made in Ferrara are available here. Videos of presentations in Paris are available here.

- The 2015 release to the public of full mission data products and scientific papers took place on 5 Feb. The data are available via the Planck Legacy Archive. Scientific papers are available here.

- Additional products (likelihood, PCCS catalogue, simulations, HFI polar. maps 100-217 GHz and TOIs) will be released in July 2015.

Planck

Planck is ESA's mission to observe the first light in the Universe. Planck was selected in 1995 as the third Medium-Sized Mission (M3) of ESA's Horizon 2000 Scientific Programme, and later became part of its Cosmic Vision Programme. It was designed to image the temperature and polarization anisotropies of the Cosmic Background Radiation Field over the whole sky, with unprecedented sensitivity and angular resolution. Planck is testing theories of the early universe and the origin of cosmic structure and providing a major source of information relevant to many cosmological and astrophysical issues. The scientific development of the mission is directed by the Planck Science Team.

Planck was formerly called COBRAS/SAMBA. After the mission was selected and approved (in late 1996), it was renamed in honor of the German scientist Max Planck (1858-1947), Nobel Prize for Physics in 1918.

 

Planck was launched on 14 May 2009, and the minimum requirement for success was for the spacecraft to complete two whole surveys of the sky. In the end, Planck worked perfectly for 30 months, about twice the span originally required, and completed five full-sky surveys with both instruments. Able to work at slightly higher temperatures than HFI, the Low Frequency Instrument (LFI) continued to survey the sky for a large part of 2013, providing even more data to improve the Planck final results. Read full story. Planck was turned off on 23 October 2013. The high-quality data the mission has produced will continue to be scientifically explored in the years to come.

Please note that these pages are largely directed to the astronomical and Planck communities.

Other Planck pages under ESA's Main Planck Portal and Sci-Tech Planck Portal are more specifically directed to the public and the press.
