What an image!
The NASA space shuttle Atlantis and the Hubble Space Telescope, seen in silhouette during a solar transit at 12:17 p.m. EDT, Wednesday, May 13, 2009, from west of Vero Beach, Florida. The two space craft were at an altitude of 600 km above the earth. It took only 0.8 seconds for them to cross the solar disc.
