The ‘Spiders’ Of Mars Have Confused Scientists So Far

Read Time:1 Minute, 54 Second

Life is being discovered on Mars, the mystery of the strange things found there is also being revealed. In this episode, scientists have made a step towards understanding the shape of spiders on Mars. These are called Araneiforms and are formed at a height of depth on the surface of Mars. They have not been found anywhere on Earth and how they came to be on Mars remains a puzzle. Scientists have now predicted that they are formed due to the sublimation of carbon dioxide into melted steam without ice.

Mars ‘spiders’

Scientists in Britain and Ireland created Mars-like conditions with the help of the Open University Mass Simulation Chamber and then saw if this process could create such a shape. For this, carbon dioxide was pierced into ice cubes and then rolled on different sizes of grains. The pressure in the chamber was then reduced to that of Mars and the blocks were placed on the surface. After this, the carbon dioxide fragments became sublimated and when they were removed, it was found that the same spider-like shape was formed by the gas.

How is it made?

Scientists believe that this can explain the shape seen on Mars. This Hypothesis has been referred to as Kieffer’s Hypothesis. In the spring, sunlight heats the surface below the snow, causing the snow to sublimate. This creates a downward pressure that passes through the cracks. With the release of gas, a spider shape is left behind. Till now this theory has been considered for decades but no physical evidence was found.

Clouds of mars

A few days ago, eight new photographs taken from the US Space Agency NASA’s Curiosity Rover were viewed with a view of the navigation camera for five minutes. They are seen moving like the clouds of the earth. These have been shared by Paul Carolina, a scientist at North Carolina State University. Even though these clouds look like clouds like Earth, the atmosphere of Mars is very thin and hence, they will be formed differently. This weather of Mars is not the same as the Earth, but it is special. In 2008, the Phoenix lander had snowfall on the surface. This ice is like earth in appearance but it is actually made of carbon dioxide like dry ice.
