Is there life on Mars—and has it left its lights on? A strange blip of light in a photo snapped April 3 by NASA's Curiosity rover has excited UFO enthusiasts, the Houston Chronicle reports. While experts suspect a pixel problem, some believe the light shining upward signals Martians.
"This could indicate there is intelligent life below the ground [that] uses light as we do," writes the editor of UFO Sightings Daily. "This is not a glare from the sun, nor is it an artifact of the photo process."
The mysterious light, spotted in a photo taken by the rover's right-hand navigation camera in a new area being studied known as the Kimberley, does not appear in the photo taken by the left-hand camera, suggesting the "light" is actually a speck of lost data, reports NBC News. It notes a photo taken the day before, again by the right navcam, shows a similar light that the left again did not capture. Whatever it is, the buzz about the blip shows that people are examining the rover photos very closely.
