(PhysOrg.com) -- In 1976, the Viking spacecraft, flying above Mars, captured an image of what appeard to be a large face on the surface of the planet. The face appeared, to many, as proof that a Martian civilization existed; beings not unlike humans must have populated Mars at one time. The famous "face on Mars" is located in the Cydonia region of Mars.

Technology has advanced a considerable amount since the original photo was taken, though. And now NASA has released a new image of the area -- one that shows quite clearly that what looks like a face in the 1976 image is really just a rocky mesa. FOXNews.com offers this explanation for the differences in the two images:

Taken from much nearer to the planet and with a substantially higher resolution camera, the features so distinctive in the original image completely vanish in the new one. The original Viking Orbiter image had much lower spatial resolution and a different lighting geometry, factors that led to the optical illusion.

The latest image was taken with the (HiRISE) camera. The camera is located on the Reconnaissance Orbiter. The Orbiter is a satellite in orbit around Mars, designed to get a good look at the . The resolution offered by these images is much higher than that taken by previous spacecraft. Images have been taken over the years, including in 1998 and 2001. The latest images were taken in 2007.

As technology has improved, though, images show the face becoming blurrier and blurrier. And now, it appears the face on Mars has disappeared altogether.
