The car-size robotic rover tag as the "Curiosity" of the National Aeronautics and Space Administration or NASA has recently captured a 'crab-like' image on the red planet's surface. The Mars Curiosity Rover is part of the Mars Science Laboratory mission (MSL) of NASA.

According to the reports, Senior Astronomer, Seth Shostak of the Search for Extraterrestrial Intelligence (SETI) cited that the 'crab-like' image is a misperception called Pareidolia, a type of illusion and the same phenomenon that makes human brains sees some shapes in clouds, walls, etc. Shostak stated NASA's captured images like 'crab' is common, he receives at least once a week.

"Those that send them to me are generally quite excited, as they claim that these frequently resemble something you wouldn't expect to find on the rusty, dusty surface of the Red Planet," Shostak quoted in news.com.au.

He added that recognising a crab in a landscape filled with wind-weathered rocks is no more surprising -- nor more significant -- than seeing a winking face in a semicolon followed by a parenthesis.

"It's usually some sort of animal, but occasionally even weirder objects such as automobile parts. Maybe they think there are cars on Mars." Shostak ended.
