An UFOlogist and the author of a blog called UFO Sightings Daily claims to have discovered a "domed city" on the surface of Mars. Scott Waring believes he made the discovery while studying photographs from NASA expeditions to the planet's surface.
"To me this looks like a domed city. Note its dark structure...like the eyes of the grey aliens right? Well they say those dark eyes of the aliens are just built in filters because their eyes or too sensitive to light," he wrote on his blog.
"What if the aliens that built this are also extremely sensitive to light? Then this structure would be perfect for that particular alien species," he continued.
Waring has made similar claims before. In February last year, he said the same thing of a photograph of the surface of Venus.
This is not the first time Waring has pointed out dome like structures on an alien surface. Earlier in February 2012, he pointed out a dome-like city in the far upper right corner of an image of planet Venus.
Rat/Lizard on Mars?
Meanwhile, earlier this week UFO enthusiasts were bitten by a rodent bug. Not literally of course, but photographs of Mars' surface, taken by NASA's Mars Curiosity Rover, appeared to show a rat or a lizard on the Red Planet.
According to the Metro, the "animal" was first spotted by a blogger in Japan, who then alerted UFO Sightings Daily. NASA has previously announced there are signs of life on the planet's surface.
In March, a statement from the space agency said that rock samples collected and analysed by the Curiosity Rover contained sulphur, nitrogen, hydrogen, oxygen, phosphorous and carbon... all of which are critical to life as we know it.
"We have characterized a very ancient, but strangely new 'gray Mars' where conditions once were favorable for life," John Grotzinger, a scientist with the Mars Science Laboratory project said.
However, before we get too carried away with the prospect of lizards on Mars, there are also reports dismissing these claims as incorrect and/or a hoax. Multiple news sources have speculated that the "discovery" could be nothing more than an ardent desire to see life on the planet.
The fact that the NASA-released photo, when compared to the version on UFO Sightings Daily, shows no such rock or feature, living or otherwise, leads one to believe the "Mars rat" is indeed a hoax.
