For a long-time, scientists have been gathering evidence that Mars was once covered in running water. Not only does it have ice on the poles (just like Earth!) but there are canals running along its surface that look suspiciously like river beds carved into the sand by water.
There are other signs of erosion all along the planet’s surface that mean scientists are slowly starting to agree that Mars once had running water.
And where there is water, there is life.
But now that evidence may have been taken up a notch after Curiosity snapped a photo of something on the Martian surface that has had experts baffled.
They think it might be a sea shell.
Scott Waring, the extra-terrestrial enthusiast responsible for the find, wrote,
“I noticed that there were two seashell-like objects within a meter of the rover. Both have a twisted end and a pointy end. Each also have a fold on one side which allows for an opening for the animal to live in. This is not the first time a seashell has been found on Mars.”
Waring was also responsible for the previous discovery of an image that appears to show two alien figures walking across the surface of Mars.
While NASA almost always dismisses the claims of UFO enthusiasts like Scott, there has been a general agreement that Mars is one of the most likely candidates for life in the Solar System outside of Earth. It once had liquid water, it still has frozen water, and there are suspicions that it still harbours running water beneath the surface of its sands. Despite this, experts are pessimistic about Mars’ actual chances of possessing complex life.
This is because Mars lacks an ozone layer like Earth and is constantly exposed to stellar radiation that would render its surface inhospitable to most forms of life.
And yet Nasa has recently revealed that colonising Mars is a long-term objective. It is hoped that the lack of water and breathable air, and the lethal doses of radiation are obstacles that can be overcome with ingenuity and science.
And who knows? They may arrive to find they have neighbours already waiting for them.
