An image taken by NASA's Mars Curiosity Rover has once again drawn the attention of anomaly hunters who have spotted a strange object sitting on the surface of the Red Planet.
The puzzling picture was taken by the rover back in March but only recently caught the attention of curious researchers.
Appearing rather artificial and seemingly reflecting sunlight at various parts, the oddity spawned the usual speculation that the rover inadvertently captured evidence for an alien presence on Mars.
Specifically, based on the general shape of the object, some have surmised that the anomaly is an ET craft.
However, skeptics have offered an explanation for what the object might be and it could actually have an Earthly origin.
