In the news this (last) month: and finally, first results from Herschel-ATLAS

October saw the first public data release from the Herschel-ATLAS project, the largest project awarded open time on the infra red satellite. Covering an area of 16-square degrees on the sky (more than 60 times the area of the full moon), the field contains more than 6000 galaxies imaged in five infra red bands (or colours) between 100 and 500 microns. The data were obtained as part of Herschel's Science Demonstration Phase in late 2009 and the ATLAS team have been working hard to process the raw images and produce catalogues of the objects detected. With so many galaxies in the field, the new data should provide much useful information to astronomers studying the evolution of galaxies over the history of the universe.
