Life on Mars? Check out these photos from Mars Rover Curiosity:

Probably just anomalies but conspiracy theorists are seizing on these photos as "proof" of Life on the Planet Mars.  From The Daily Mail:

Since Nasa’s mission to Mars got under way on August 6, the Curiously Rover has beamed some astonishing images back to Earth that have left scientists and amateur star-gazers alike scratching their heads and envisioning UFOs.But even seasoned alien watchers were puzzled when the rover making its way through the Red Planet send back the image of what appeared to be a fossilized human finger.YouTube user StephenHannardADGUK, part of a group called Alien Disclosure UK, who had caused a stir on the Internet last week after pointing out white ‘flying objects’ zooming across the Martian sky called attention to a collection of ‘mysterious’ items he spotted in a video from Gale Crater.

Martian footwear: Another rock that caught the attention of the UFO enthusiast made him think of a long-forgotten shoe or sandal on the surface of the Red Planet
‘Mars Curiosty(sp) captures a possible ancient finger, a dome shaped object, a shoe or sandal and a possible Martian creature,’ Hannard wrote in the video description. ‘Are these anomalies real, tricks of the light or something else, as always you decide.’The image shows what appears to be a rock shaped like a digit with a faint outline at one end that vaguely resembles a fingernail. Another rock found nearby resembles an overturned sandal, and a crevice on another geological formation looks like a smiling Martian critter, NBC reported.Nasa, however, has so far made no ground-breaking announcements regarding the discovery of life forms – or Martian footwear, for that matter - on the Red Planet, leaving UFO enthusiasts guessing and wondering.
On August 18, Hannard posted footage in which he applied a series of filters to a Curiosity, revealing what he claimed to be four objects resembling flying saucers hovering in the sky.

‘Four objects caught by Mars Curiosity, very difficult to make out on original image so I have used a few filters to highlight,’ he said in the video description. ‘What are these four objects? UFOs, Dust particles, or something else? As always you decide.’
Experts, however, came out saying that the four ‘objects’ are actually just dead pixels in the rover's CCD camera — single points in the camera's imager that have lost functionality and register as white.
Marc D'Antonio, a photo and video analyst for MUFON [Mutual UFO Network], told Huffington Post, ‘I fully concur at this point that these are dead pixels on the imager. All CCD (cameras) have them, and in a bland atmosphere like that at Mars, they would be very obvious as opposed to an active atmosphere like Earth, where they could end up hidden for a long time before anyone noticed them.’

The YouTube video - posted by a Stephen Hannard - puts the photograph through many different filters to try to find more clues as to their existence. A fourth blob can be seen to the top of this image

Just two days after the rover touched down on Mars, back to Earth caused many UFO hunters to perk up. It seemed that Nasa has itself captured something very strange on camera, including a strange white light dancing across the horizon of the red planet, and four blobs hovering in the sky
While the images are certainly a curiosity, Nasa and photography experts insist that these are nothing more than blemishes on the images, picked up by the camera lens sitting on the rover at a distance of 350 million miles away.
