Earth's true colours

Rosetta: Earth’s true colours

20 November 2007

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 above 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 observed Earth’s night-side.

This image shows a simulated view of Earth as seen from Rosetta's position.

The same view was seen by the OSIRIS Wide Angle Camera (WAC). It is shown in false colour to emphasise city lights seen at night.

This image was acquired on 13 November 2007 at 20:30 CET using the WAC with a red filter.
