A unique composite image of Earth captured on Oct 12 by the US space agency's Lunar Reconnaissance Orbiter, from its vantage point in orbit around the Moon, seen in this picture handed out by Nasa on Saturday. Earth appears to rise over the lunar horizon, with its centre just off the coast of Liberia. The large tan area in the upper right is the Sahara Desert, and just beyond is Saudi Arabia. The Atlantic and Pacific coasts of South America are visible to the left. This image is a composite of a series of images taken on Oct 12, when the Lunar Reconnaissance Orbiter was about 134km above the Moon's far-side crater Compton.
