In this video, former astronaut Buzz Aldrin speaks about the future of space exploration and says the public would be interested in a monolith on Phobos, one of the two small moons that revolve around Mars.
Astronomers estimate the rectangular structure measuring five meters across, was photographed by a super high resolution camera on the Mars Reconnaissance Orbiter. The giant monolith juts out of the planet’s surface casting a huge shadow below. The monumental structure resembles the black monolith seen in Stanley Kubrick film 2001: A Space Odyssey. In the movie the structure is believed to be a key to man’s evolution.
Although there is much hype about the monolith such as an alien species placed there, or is a remnant left over from creatures once living on the red planet. I can imagine two other possibilities. Either it is an optical illusion or one huge crystal. What do you imagine it to be ?
