Decode the mysterious circle in Antarctica

Scientists taking part in the reconnaissance flight over the Southeastern region have discovered a mysterious circular-like structure in the often flat and unspecified ice.

What the team observed seemed to be a series of broken "icebergs" , which were covered by a round scar, about 2 kilometers wide. Around there are a few smaller circular scars on the ice.

Experts later discovered two separate studies that reported that an asteroid fell into the region in 2004. In it, a study noted the detection of a series of low-frequency, low-threshold sounds. people heard (20 Hz) on September 2, 2004. Six detectors around the world discovered this low-frequency sound from an exploding meteorite, allowing scientists to pinpoint its location somewhere above the South East East.

In a separate study, scientists at the Davis Station, Australia's permanent base off the East Antarctic coast, reported seeing a high streak of dust in the atmosphere around the time. They surmised, the falling object would land on the ice shelf.

The findings imply, a meteorite is about the size of a house with a width of about 7-10 meters and weighs about 600-1,000 tons, crumbling in the atmosphere above Antarctica. When exploding in the sky, meteorites are moving at a speed of 46,800 km / h and create a destructive power equivalent to 12,000 tons of TNT.

The debris created by the explosion then fell to Earth, crashing into the Antarctic ice region. Researchers are currently considering drilling down the ice below the impact crater to see if they can learn more about the culprit causing it.

Geophysicist Dr. Graeme Eagles explains: "If the meteorite crumbles before crashing into the ice shelf, perhaps some of its fragments don't have enough energy to penetrate the ice shelf and can lie above it. "We can find evidence of a layer of dust on the ice, around the impact hole and under the snow that has accumulated for the past 10 years. I think it is worth it for us to study."
