NASA found where it came from that extravagant rectangular iceberg



This iceberg has all the right angles.

A very cold internet star was born in October when a NASA research flight on Antarctica captured a photo of a strangely square iceberg. While some people joked about a possible alien origin, NASA now has the test of the very terrestrial journey of Berg.

Scientists thought initially that the weird iceberg, photographed by the IceBridge Operation team, had just had the Larsen C. ice shelf. That's the ice shelf that gave us monster iceberg A-68 in 2017. But the real story is much longer.

The researchers sleuthed the starting point of the iceberg with the help of images from the Landsat 8 of NASA and the Sentinel-1 satellites of the European Space Agency.

The iceberg originally exploded on the ice shelf in November 2017. Floats north into a water channel between the ice shelf and the A-68 iceberg.

The iceberg is circled in this Landsat 8 image as of October 14.

"Long-lasting berg box did not make it undamaged; it broke into small bits," reports the NASA Earth Observatory. Berg really seems to be more a trapezoidal shape than a pure rectangle in a Landsat 8 satellite image from October 14, a few days before IceBridge Operation saw it.

The infamous geometric iceberg shone brilliantly, but briefly. NASA says that the open water has changed, where it will slip into the warmer environment.
