Scientists finally explained the mysterious “spider” found on Mars



I regret to inform you that giant spiders do not actually live on Mars.

Creepy creeper

For decades, scientists have been puzzled by the strange structures at the South Pole of Mars, which look like giant spiders.

This is not to say that astronomers worry that future Martian outposts will be attacked by giant alien arthropods, but this abnormal geological structure has not been explained for many years. life sciences report. Now, a group of scientists from the United Kingdom seems to have solved this problem, thanks to a large piece of dry ice, a pile of mud and a machine that can reproduce the Martian atmosphere on Earth.

Sublime experiment

As early as 2003, researchers assumed that the “spider” at 3,300 feet was related to the sublimation of carbon-rich ice on Mars, or directly changed from solid to gas, but there was no way to test it. life sciences report.

However, based on research published in the journal Science last month, British researchers have now been able to create smaller versions of formations in the laboratory by pressing dry ice against warm deposits. Scientific report. When they did this in an artificial Martian atmosphere, the ice sublimated and radiated outward, carving leg-like ditches in the soil.

Proving ground

The mystery has been solved! In addition to confirming what the spiders on Mars are made of, the fact that Martian-like experimental conditions have formed the same shape as real Mars shows that scientists now have powerful tools to study Martian phenomena without actually going to Mars.

Lauren McKeown, a planetary scientist and lead research author at the Open University, said in a press release: “This research provides the first set of empirical evidence for surface processes that are believed to change the polar landscape on Mars. “The experiment directly shows that we can carve out the spider patterns we observe from orbit on Mars by directly converting dry ice from solid to gas.”
