‘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.”’
