Studies have shown that the meteorite broke up in the atmosphere before its pieces crashed into ice and formed the "ring" with a diameter of two kilometers.
Researcher Graham Eagles, head of geophysicists at the station "Princess Elizabeth", said that they believe that it is - a crater, which was formed by meteorite.
Researchers are going to drill the ice near the crater to find traces of the fallen celestial body.
Scientists say the crater is left by meteorite, the signal is recorded on September 2, 2004.
