Ziggy plays the guitar, And British scientists experimented with a large amount of dry ice to try to figure out the reason behind the strange alien pattern called “alien”.Spider on Mars. “
The patterns that can be seen in the satellite images of the “Red Planet” Antarctica are certainly not real spiders. But the black branch shapes carved on the surface of Mars look creepy, so much so that researchers called them “spider-like” (meaning “spider-like”) after they discovered these shapes more than two decades ago.
The huge shape is 3,300 feet (1
“This research provides the first set of empirical evidence for surface treatment, which is believed to change the polar landscape. Mars“, the lead author of the study, planetary scientist Lauren McKeown of the Open University of the United Kingdom, Said in a statement. “Experiments directly show that we can carve out the spider patterns we observe from orbit on Mars by directly converting dry ice from solid to gas.”
The Martian atmosphere contains more than 95% carbon dioxide (CO2), According to NASA, And the large amount of frost that forms around the poles of the earth in winter is also made of carbon dioxide.in a Study in 2003Researchers hypothesized that spiders on Mars may form in spring because sunlight penetrates the translucent CO2 ice layer and heats the ground below. Heating causes the ice to sublime from its bottom, building pressure under the ice, until it finally breaks. The hypothetical team speculated that the piercing gas escaped through cracks in the gushing feathers, leaving behind the jagged spider leg patterns that are now visible on Mars.
Until recently, scientists had not been able to test this hypothesis on Earth where atmospheric conditions vary widely. But in this new study, the researchers used a device called the “Open University Mars Simulation Room” to create a small piece of Mars on Earth. The team put sediment particles of different sizes into the room, and then used a system similar to the claw machine you see on the local arcade to suspend a block of dry ice on the particles. The team adjusted the room to mimic the atmospheric conditions of Mars, and then slowly lowered the dry ice onto the grain.
Experiments have proved that the spider sublimation hypothesis is valid. Regardless of the size of the deposited particles, dry ice will always sublime when it comes in contact with them, and the escaping gas will push upwards, carving spider-leg-like cracks along the way. According to the researchers, when the grain is thinner, the spider legs have more branches, and when the grain is thicker, there are fewer branches.
Although uncertain, these experiments provide the first physical evidence of how spiders on Mars may have formed. Now, this is not sublime.
