With a 3.5 m diameter, the Herschel Space Observatory is the largest astronomical telescope ever put into space. Since its launch in May 2009, it has been giving astronomers a new window on the universe, producing high resolution images of our own Milky Way Galaxy and other galaxies at far-infrared and sub-millimetre wavelengths. I will lead you on a visual tour through recent Herschel results, with a focus on images of nearby galaxies, which are my own focus of research.
