We have constructed the first all-sky map of the thermal Sunyaev-Zeldovich(tSZ) effect by applying specifically tailored component separation algorithmsto the 100 to 857 GHz frequency channel maps from the Planck survey. These mapsshow an obvious galaxy cluster tSZ signal that is well matched with blindlydetected clusters in the Planck SZ catalogue. To characterize the signal in thetSZ map we have computed its angular power spectrum.  At large angular scales ($\ell < 60$), the major foreground contaminant isthe diffuse thermal dust emission. At small angular scales ($\ell > 500$) theclustered Cosmic Infrared Background (CIB) and residual point sources are themajor contaminants.  These foregrounds are carefully modelled and subtracted.  We measure the tSZ power spectrum in angular scales, $0.17^{\circ} \lesssim\theta \lesssim 3.0^{\circ}$, that were previously unexplored. The measured tSZpower spectrum is consistent with that expected from the Planck catalogue of SZsources, with additional clear evidence of signal from unresolved clusters and,potentially, diffuse warm baryons.  We use the tSZ power spectrum to obtain the following cosmologicalconstraints:  $\sigma_8(\Omega_{\mathrm{m}}/0.28)^{3.2/8.1}=0.784 \pm 0.016 (68% C.L.).  Marginalized band-powers of the Planck tSZ power spectrum and the best-fitmodel are given.  The non-Gaussianity of the Compton parameter map is further characterized bycomputing its 1D probability distribution function and its bispectrum. Theseare used to place additional independent constraints on $\sigma_{8}$.
