In Antarctica, a giant hole was found, comparable in size to Lake Superior (North America), whose area is more than 82 thousand square kilometers, Motherboard reports.
It is noteworthy that experts still cannot understand how the hole formed. As noted by a professor at the University of Toronto, physicist Kent Moore, the usual places of open water (polynyas), surrounded by sea ice, are formed in the coastal regions of Antarctica.
However, in this case, the polynya opened far from the boundary between the ice and the sea.
- It is hundreds of kilometers from the ice edge. If we did not have a satellite, we would not have known about the existence of a very remarkable mysterious hole. It feels like as if someone just broke the ice- said Kent Moore.
The specialist explained that in the 70s of the last century, a similar phenomenon was already observed in Antarctica. However, at that time it was left without proper attention, since scientists had much less resources to study such formations.
As a result, the hole "closed in" and was not observed for the next 40 years. However, this autumn the polynya reopened.
One of the versions of its appearance is associated with global climate change - researchers are in no hurry to draw conclusions.

A Huge Iceberg Five Times The Size Of Malta Broke Away From Antarctica
From the Emery Ice Shelf in Antarctica, an iceberg, nicknamed "Loose Tooth" and license plate "D28", recently broke away. The iceberg is 631 square miles and 210 meters thick. The island of Malta could fit on it five times. This is the largest iceberg observed by humans in the past 50 years, and at the same time scientists convince the public that the event has nothing to do with global warming. According to scientists, this piece of glacier caught their attention back in 2002 and studied
Huge Cave Entrance Discovered On Antarctica Map
According to the author of the YouTube channel "Third Phase From The Moon", who recently posted a video with this discovery, most likely a secret military base got on the cards. But whose? The object is located at 62 ° 0'14.36 "S 57 ° 45'15.63" W on the ice coast of King George Island in the South Shetland Islands archipelago. This cave can only be seen on satellite imagery from 2007. On earlier and later maps, the cave is covered with snow. If strong
In The Phobos-Grunt Case, A Version Emerged With The Impact Of The American Radar
Phobos Grunt destroyed the American radar. This version was put forward by an unnamed expert of Roskosmos, to whom the Kommersant edition refers. According to the specialist, in the first hours after the launch, the spacecraft could get into the coverage area of a powerful radar station, which is located on the Marshall Islands. A failure in electronics in Roskosmos was initially called the most likely reason why Phobos-Grunt did not go on a given trajectory
