Curiosity appears to have discovered... a Martian campfire. NASA, of course, says it's nothing of the sort -- rather than an indication of extraterrestrial life, it's probably just a bright spot caused by the sun reflecting off a rock, or errant cosmic radiation striking the camera's sensor. A prominent ufologist, however, claims that it's an artificial life source, and that "NASA could go and investigate it, but hey, they are not on Mars to discovery life, but there to stall its discovery."
