True colour images of Earth as seen by Rosetta's OSIRIS camera are now available. The pictures were taken on 13 November during the swing-by, and on 15 November, as Rosetta left on its way to the outer Solar System, after the swing-by.
After its closest approach to Earth, Rosetta looked back and took a number of images using the Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) Narrow Angle Camera (NAC). This particular image was acquired 15 November 2007 at 03:30 CET. The image here is a colour composite of the NAC orange, green and blue filters. At the bottom, the continent of Australia can be seen clearly. During the swing-by, OSIRIS also observed Earth's night-side.
