Looking a bit like a speck of dust on the surface of the Sun, this stunning picture taken by the French astro-photographer  Thierry Legault in fact shows the unique sight of the space shuttle Atlantis next to the International Space Station, silhoutetted against the Sun.
 
The shuttle and ISS can be seen in orbit some 250 miles above the Earth, with the Sun as the backdrop,  93 million miles away.

An unusual and spectacular image!
