While surveying the positions of over a billion stars, ESA's Gaia mission is also measuring their colour, a key diagnostic to study the physical properties of stars. A new image provides a preview of Gaia's first full-colour all-sky map, which will be unleashed in its highest resolution with the next data release in 2018.

The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image. The tiny NGC 1510 and its colossal neighbour NGC 1512 are at the beginning of a lengthy merger, a crucial process in galaxy evolution.

Two new catalogues, based on data from ESA's Herschel Space Observatory, have been released to the scientific community. The point source catalogues are examples of a new type of data product from two of Herschel's instruments, SPIRE and PACS. These catalogues are part of the lasting legacy of the Herschel mission, and will further facilitate...
