An anonymous reader writes: According to the UK Metro, pictures of an alleged "alien" walking down a hill, shot by the Mars Exploration Rover Spirit, are causing a stir on blogs and forums all over the Internet. The picture was first seen on a Chinese website, according to the article. Although the figure looks more like an odd-shaped rock to me, this is what Metro has to say: 'At first experts missed this clear evidence of ET living on the Red Planet. It wasn't until space and science fiction enthusiasts became involved that the images were taken more seriously.' Also see the NewsTime 7 version of the article.
