These images, part of a series beamed back to Earth by the Curiosity rover, have provoked considerable debate among UFO believers.
The pictures, taken by Curiosity’s right-hand navcam on April 3, appear to show an artificial light flaring up in the distance by a hillside.
An artificial light source was seen this week in this NASA photo which shows light shining upward from...the ground. This could indicate there there is intelligent life below the ground and uses 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% indiction it is from the surface. Sure Nasa could go and investigate it, but hey, they are not on Mars to discovery life, but there to stall its discovery.
