NASA Mars Rover Curiosity Sees 'Evening Star' Earth

This view of the twilight sky and Martian horizon taken by NASA's Curiosity Mars rover includes Earth as the brightest point of light in the night sky.
Researchers used the left eye camera of Curiosity's Mast Camera to capture this scene about 80 minutes after sunset on the 529th Martian day, or sol, of the rover's work on Mars (Jan. 31, 2014).
