If there are living beings on Mars, then surely they should play football. So the hunters for amazing artifacts in the Martian images discovered a small "ball".
Captured on December 20, 2016 by the Curiosity rover, the image shows a small dark ball lying on red dust amidst rock debris.
And in a photograph taken back in 2011, when the same rover just landed on the surface of the Red Planet, you can see exactly the same ball lying in the same place. And what is interesting, for so many years it has not been covered with Martian dust at all, as happened with the rocks surrounding it.
Some researchers suggest that the ball is made of marble and is a Martian spherule, formed by the ejection of molten magma by volcanoes. The same balls, called blueberries because of their blue hue, were discovered on Mars by the rover Opportunity in 2004.
According to another theory, such balls form when groundwater flows through porous rocks, causing chemical reactions that turn the precipitating iron minerals into small, layered balls.
“Simple geologic processes can create these round objects,” says Dr. Hap Maxwin of the University of Tennessee at Knoxville.
This marble ball is just one of the latest stunning "discoveries" discovered by researchers in photographs from Mars.
