The following article contains several NASA photographs of light apparently emanating outward from the surface of Mars a short distance from the rover vehicle. http://www.chron.com/news/strange-w...t-coming-5382677.php?cmpid=hpts#photo-6131487 Currently, there is no official explanation from NASA. But before leaping to the conclusion that the light is artificial and comes from an underground civilization as this article does, it is perhaps better explained as a cosmic ray hitting the camera. Also recall that scientists have recently affirmed similar lights on Earth originating prior to and during earthquake events. In brief, it is explained that pressures within rock formations cause charge separation and ionization which result in glowing particles releasing into the atmosphere.
