This image of northeast Africa and the Arabian Peninsula was taken from an altitude
     of about 500,000 kilometers (300,000 miles) by the Galileo spacecraft on
     December 9, 1992, as it left Earth en route to Jupiter. Visible are most of Egypt
     (left of center), including the Nile Valley; the Red Sea (slightly above center); Israel;
     Jordan, and the Arabian Peninsula. In the center, below the coastal cloud, is
     Khartoum, at the confluence of the Blue Nile and the White Nile. Somalia (lower
     right) is partly covered by clouds.
