NASA has released a photo of Mars with a white light or object that appears to be floating.
NASA's Curiosity rover took the black and white photograph using Navcam, a navigational camera that some robotic rovers or spacecrafts use. It serves as the rover's "eyes" to take wide angle photographs.

No one is sure what the light is or what caused it to occur. Photos taken seconds before and after do not show the mysterious white phenomenon.
The car-sized rover was launched in November 2011 and landed on Mars in August 2012. Since then, it has been sending images of Mars's surface back to Earth.
JPL scientist Dr. Justin Maki did not believe the 2014 photo was adequate evidence for extraterrestrial life. He listed three possibilities for the occurrence.
Another possibility for the bright spots is when sunlight enters through a vent hole into a camera's sensor.
Finally, it could also be "a cosmic ray striking the camera's detector."
"This could indicate there is intelligent life below the ground and they use light as we do. This is not a glare from the sun, nor is it an artifact of the photo process. Look closely at the bottom of the light. It has a very flat surface giving us 100 percent indication that it is from the surface," he wrote.
