Mars rover photos spark
by Andrea Bellemare
It was bound to happen. NASA's Mars rover Curiosity has been beaming pictures and videos of the Red Planet back to Earth and, in some of those pictures, there appear to be things that some people think could be UFOs. Maybe. The video above was posted by YouTube user StephenHannardADGUK of the Alien Disclosure Group, who says:
"Four objects caught by Mars Curiosity, very difficult to make out on original image so I have used a few filters to highlight. What are these four objects? UFOs, Dust particles, or something else? As always you decide." The video sparked debate, and one expert said that the so-called UFOs were merely dead pixels on the camera that were spotted more easily on Mars because of the "bland atmosphere." But his conclusion didn't stop the Twitter jokes.
