Washington: A photograph of Mars sent by Curiosity rover, which features an apparent blip of light on the horizon has sparked people`s interest with UFO enthusiasts speculating that it could be an artificial light source.
Rover`s right navigation camera clicked the image. A close-up of the light makes it look like it has a flat bottom and rises upward, where it dissipates, CNET reported.
Doug Ellison, visualization producer at NASA`s Jet Propulsion Laboratory , wrote on his Twitter account "It`s not in the left-Navcam image taken at the exact same moment. It`s a cosmic ray hit."
