The bright Evening Star visible in this picture of the twilight sky above the Martian horizon is planet Earth.
The incredible image is the first ever taken of Earth from the surface of the Red Planet 34million miles away.
NASA’s Curiosity Rover captured the spectacle a week ago and the agency tweeted the image tonight with the message: “Look Back in Wonder… My 1st picture of Earth from the surface of Mars.”
It was taken about an hour after sunset with our planet appearing as the brightest dot in the night sky.
A NASA spokesman said: “A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright ‘Evening Stars’.”
In this enhanced image above, the moon can also be made out underneath Earth.
It is exploring the Red Planet for signs that it was ever able to support life forms and to look at it climate with a view to the possibility of future manned missions.
It is equipped with 17 cameras and a microscope to examine any materials it collects from the Martian surface with its robotic arm, equipped with a drill, brush, scoop and sieve.
Curiosity is the fourth unmanned NASA rover sent to Mars since 1996.
