Earth limb seen by OSIRIS

The Optical Spectroscopic and Infrared Remote Imaging System (OSIRIS) camera on board Rosetta observed Earth during its swing-by last night.

This image was taken with the Wide Angle Camera (WAC) at 20:05 CET, about 2 hours before the closest approach of the spacecraft to Earth. At the time Rosetta was about 75000 km from Earth. A sun-illuminated crescent can be seen around Antarctica. The image is a colour composite combining images obtained at various wavelengths.
