April 8, 2014 - A NASA camera on Mars has captured what appears to be artificial light emanating outward from the planet's surface.
The photo, beamed millions of miles from Mars to the Jet Propulsion Laboratory in Pasadena, Calif., was taken last week, apparently by one of two NASA rovers on the red planet.
Although the space agency hasn't issued any official statement yet about the phenomenon, bloggers and NASA enthusiasts have started chiming in.
Scott C. Waring, who maintains the website UFO Sightings Daily, posted the photo April 6.
Waring noted that the light shines upward, as if from the ground, and is very flat across the bottom.
"This could indicate there there is intelligent life below the ground and uses light as we do," Waring wrote on his website. "This is not a glare from the sun, nor is it an artifact of the photo process."
Earlier this month, NASA announced that on April 2, the Curiosity rover drove the last 98 feet needed to arrive at "the Kimberley," a spot where it can study rock clues about ancient environments that might have been favorable for life, according to a news release.
