NASA's Curiosity rover has captured a spectacular sight from the surface of Mars: The first-ever photo of Earth alongside the Red Planet's moon Phobos.
Using its Mast Camera, or Mastcam for short, Curiosity photographed Earth setting the Red Planet night sky while one of Mars' two moons, Phobos, rises on Sept. 5. The rover's new view, which consists of five short exposures and 12 long exposures, captures a rocky Martian outcrop in the foreground and an expansive sky with Earth and Phobos seen in the upper right. An inset in the image, which NASA shared online on Sept. 13, identifies Phobos on the left and Earth on the right.
