ESA's Planck mission is the source for a new catalogue, eagerly awaited by the scientific community. The Second Planck Catalogue of Compact Sources uses data from the entire mission to identify tens of thousands of compact sources, as well as providing polarisation data for several hundred of them. The new catalogue surpasses its predecessors not only in the quantity of sources but also in the quality of data. It will be an asset to astronomers working in a wide range of fields.
