(CNN) — A lot of people are talking about a mysterious, bright light on Mars.
Here’s a NASA photo of what we’re talking about.
The Mars Rover snapped a picture of the light a few days ago.
Some space enthusiasts say they think it’s being projected from underground and is a sign of possible life.

Images taken by NASA’s Curiosity Mars rover on April 2 and April 3 include bright spots, which might be due to the sun glinting off a rock or cosmic rays striking the camera’s detector.
The image from April 3, from Curiosity’s Navigation Camera, is online at: http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA18077
The rover took the image just after arriving at a waypoint called “the Kimberley.” The bright spot appears on a horizon, in the same west-northwest direction from the rover as the afternoon sun.
“In the thousands of images we’ve received from Curiosity, we see ones with bright spots nearly every week,” said Justin Maki of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., leader of the team that built and operates the Navigation Camera. “These can be caused by cosmic-ray hits or sunlight glinting from rock surfaces, as the most likely explanations.”
If the bright spots in the April 2 and April 3 images are from a glinting rock, the directions of the spots from the rover suggest the rock could be on a ridge about 175 yards (160 meters) from the rover’s April 3 location.
The bright spots appear in images from the right-eye camera of the stereo Navcam, but not in images taken within one second of those by the left-eye camera. Maki said, “Normally we can quickly identify the likely source of a bright spot in an image based on whether or not it occurs in both images of a stereo pair. In this case, it’s not as straightforward because of a blocked view from the second camera on the first day.”
