1. APOD: 2001 December 11 - Venusian Half Shell
... 2001 December 11 . Venusian Half-Shell . ... Explanation: Venus , second planet from the Sun, appears above imaged for the first time ever in x-rays (left) by the orbiting Chandra Observatory . ... As the atoms rapidly decay back to their stable ground states they emit a "fluorescence" x-ray, creating a glowing x-ray half-shell above the sunlit hemisphere. More x-ray emitting material can be seen looking at the edge of the shell, so the edge appears brighter in the x-ray image. ...
