Is it a rock? A shadow? Or a 'Woman on Mars’? Internet divided on NASA’s Mars photograph

Nasa's Curiosity Rover has been prowling the surface of the red planet for the past few years and has made several discoveries over the course of its adventures.

But none are as intriguing as the discovery of a 'woman' 'with long hair and a dress' by a blogger who has written extensively about the woman in a blog, unsurprisingly called UFO Sightings Daily. Before you read further, have a long and clear look at the photograph below, released by Nasa as part of a series of high-resolution images captured by Curiosity. What do you see? A clear picture of Mars' surface, the rocky terrain maybe? Can you spot anything unusual? Look again. The encircled area is where the 'woman' stands, according to UFO Sightings Daily. In a post titled 'A strange woman walking on Mars? News intriguing images of Mars are discussed on the Internet', the writer elaborates on the vision, writing, "It seems there is a woman standing on top of a cliff, with long hair, wearing a dress, watching the Jeep probe. Just above, it appears an impression that leads to something similar to a manhole with a lever at the top. And next, it is something that looks like a small building or a tent. Logo on your left, there seems to be a painting on the wall (a greeting?)." These points are illustrated with zoomed and highlighted images the apparent shapes. The 'Woman on Mars' images were to quick to go viral with some speculating about its authenticity while most joked about the unlikeliness of signs of life on Mars, much less humanoid signs. While the internet debates (and jokes) about the woman who made it to Mars, the whole idea seems to be more like a Rorschach test — 'What can you see in the image'? Some may see a rock protrusion, others a shadow and maybe some will see the apparition. So, what do you see?
