NASA has detected a large, ancient skin that is buried under two kilometers of ice in the northwest country. Even more spectacular, the second shape is found in the area's thick ice in the past few months.
Extending over 36.5 kilometers (22 miles), The crack could have been created with asteroid effects in the past over 2.6 million years ago, according to a survey published on Monday Geo-Scientific Research LettersThe Post If the feature is shown to be an asteroid strike, it will become the most recognized peak 22ra on Earth.
Scientists have identified 200 peppers affecting our planet, but this is only the second time in the history of hunting under ice record. In November, NASA published that it was seen as the first subdivision of a subdivision that was buried under the Hiawatha Greenland Genetics, just 183 kilometers away from the new site.
Encouraged by that discovery, a team led by NASA scientist, Joseph MacGregor, began to scan the Territories for other craters. The new and larger pit is more than the Hiawatha site.
The two features that display satellite images and aircrafts captured by NASA's Airbus IceBridge aircraft fleet can be seen.
Because they were so close to each other, MacGregor and his colleagues considered what these societies were created with the only impact event. A brown data system may have been successful on Earth, or has asteroid broke into two pieces during indoor access.
But ideas on the landscape of the new pit show that it is much worse than the Hiawatha crack, suggest that they can not be created at the same time.
"The morphology of the second structure is weaker [and] the preceding ice is consistent and over, "MacGregor and his authors write in the study." We decide that the well-known structure is very like skin affects, but it is unlikely that two of the skin will affect Hiawatha. "

The Hiawatha crack may have been created in the last 100,000 years. It can take more research to limit the age of the second shadow, but it seems to have been created within the Pleistocene period, which began 2,588,000 years ago. Based on the approximate age of a sheet of ice cover, created 79,000 years ago, the team said.
The structure still has no official name, but the authors suggested that it was the paterson's tarry. This name would honor the late ecologist Stan Paterson, who helped to reconstruct climate data for the last 100,000 years. using green berries from Greenland.
"It should be examined with sub-archaeological screws under Greenland and Antarctica, as our discovery emphasizes the ability of the tape recorders to both burial and to preserve evidence of earthquakes, "said the crew.
