The Curiosity Rover has just sent back to Earth an image that is believed to be a strange object appearing on the red planet.
In the video, four round objects appear in the air and white light on the horizon. After seeing the image, some people think that it could be an alien ship monitoring humans when entering space.
NASA scientists have yet to give an official explanation for the hidden image. According to Marc Dantonio, a UFO expert, those are dead pixels. People who use phones, computers or cameras can take pictures and can be strange.
