The Optical Spectroscopic and Infrared Remote Imaging System (OSIRIS) camera on board the Rosetta spacecraft observed Earth during its swing-by in November 2007. A sun-illuminated crescent can be seen around Antarctica in this image that is a color composite combining images obtained at various wavelengths.
This image was taken with Rosetta’s Wide Angle Camera, about 2 hours before its closest approach to Earth.
