**Abstract:** These lecture from the 100th Les Houches summer school
on "Post-planck cosmology" of July 2013 discuss some aspects of the
Planck mission, whose prime objective was a very accurate measurement of
the temperature anisotropies of the Cosmic Microwave Background
(CMB). We announced our findings a few months ago, on March 21^{st},
2013. I describe some of the relevant steps we took to obtain these
results, sketching the measurement process, how we processed the data to
obtain full sky maps at 9 different frequencies, and how we extracted
the CMB temperature anisotropies map and angular power spectrum. I
conclude by describing some of the main cosmological implications of the
statistical characteristics of the CMB we found. Of course, this is a
very much shortened and somewhat biased view of the Planck 2013
results, written with the hope that it may lead some of the students to
consult the original papers.
