  The Planck Collaboration has recently released maps of the microwave sky in
both temperature and polarization. Diffuse astrophysical components (including
Galactic emissions, cosmic far infrared (IR) background, y-maps of the thermal
Sunyaev-Zeldovich (SZ) effect) and catalogs of many thousands of Galactic and
extragalactic radio and far-IR sources, and galaxy clusters detected through
the SZ effect are the main astrophysical products of the mission. A concise
overview of these results and of astrophysical studies based on Planck data is
presented.
