A NASA camera has captured what seems to be an artificial light emanating outward from the surface of Mars.
The photo was taken last week by one of two NASA rovers currently on the Red Planet.
The picture was posted by Scott C. Waring, who runs the website UFO Sightings Daily. He posted the photo on April 6.
Though the space agency hasn't released an official statement yet, many bloggers have speculated what the light could be.
Waring himself pointed out that the light shines "upwards" from the ground, and is very flat across the bottom.
"This could indicate there is intelligent life below the ground and uses light as we do," Waring said on his website. "This is not a glare from the sun, nor is it an artifact of the photo process."
Justin Maki, an imaging scientist at NASA's Jet Propulsion Laboratory, NASA's lead center for robotic exploration of the Solar System in Pasadena, Calif., said to ABC News that he believes the bright spots are single images taken by the rover's Navigation Camera on NASA's Curiosity rover.
"In the two right-eye images [on the rover] the spot is in different locations of the image frame and, in both cases, at the ground-surface level in front of a crater rim on the horizon," Maki said. "One possibility is that the light is the glint from a rock surface reflecting the sun," he said.
The light could have been caused by a technical error as well. Which previously occurred on other Curiosity cameras and other Mars rovers, according to Maki.
"The rover science team is also looking at the possibility that the bright spots could be sunlight reaching the camera's CCD directly through a vent hole in the camera housing," Maki said. "We think it's either a vent-hole light leak or a glinty rock."
NASA announced on April 2 that its Curiosity rover drove the last 98 feet needed to reach "the Kimberley," a location where they believe it can study rock clues about ancient environments that might have been favorable for life, according to a recent news release.
