Images captured by Nasa’s Mars Curiosity rover have sparked debate among UFO believers, with some suggesting they “could indicate that there is intelligent life below the ground” on the planet.
The pictures, taken on April 3 by the Curiosity rover’s right-hand navcam, appear to show a light in the distance, flaring upwards from behind the hillside.
But the theories of UFO enthusiasts have been firmly dispelled by imaging expert Doug Ellison from JPL, Nasa’s robotic exploration wing. He blames the glimmer on a “cosmic ray hit” – when high energy particles hit a surface.
