According to the fringe sector of the Internet, Mars is practically teeming with aliens.

Since NASA’s Curiosity rover touched down on the Red Planet two weeks ago and powered up its cameras, it has already managed to photograph several alleged UFOs and other “anomalies” in the surrounding landscape.
From classic flying saucers to an absurdly out-of-place fossilized human finger, here’s a rundown of what UFO believers claim to have found in Curiosity photos so far. [Gallery of Mars 'UFO' Photos]
Horizon anomaly (aka impact cloud)
Speculation about Martians in Curiosity’s midst got off to a running start when the very first sequence of photos taken by the rover raised questions. A hazy, distant object mysteriously appeared and then disappeared in consecutive images of the Martian horizon, perplexing even NASA scientists at first.
But the much-discussed “anomaly” turned out not to be a sign of alien activity, but rather the plume of dust kicked up by the sky crane that delivered the rover close to the Martian surface, then veered off and struck the ground some 2,000 feet (600 meters) away.
“We believe we’ve caught what is the descent stage impact on the Martian surface,” said NASA engineer Steven Sell, sky crane specialist on the Curiosity mission.
Flying saucers (aka dead pixels)
In footage posted to YouTube Aug. 18, user “StephenHannardADGUK” applies a series of filters to a Curiosity image of the nearby rim of Gale crater, revealing what he says are four flying saucer-like objects stationed in the sky. More than 700,000 people have since given the video a gander.
“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 say 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.
