A very cold Internet star was born in October when a NASA Surveying Flight over the Antarctic took a picture. While some people joked about a potential alien source, NASA now has evidence of the mountain's very earthly voyage.
The scientists initially believed that the strange iceberg, photographed by the Operation IceBridge team, had recently calved from the Larsen C ice shelf. This is the same ice shelf that gave usin 201
Using images from NASA's Landsat 8 and NASA, researchers located the iceberg's starting point, the European Space Agency's Sentinel 1 satellites.
The iceberg was originally calved by the Ice Shelf in November 2017. He floated north in a water channel between the ice shelf and the A-68 iceberg.
"The once-long Rectangular Mountain has not survived unscathed, it has broken up into smaller pieces," NASA's Earth Observatory reports. In fact, the mountain appears to be more of a trapezoidal shape than a pure rectangle on a Landsat 8 satellite image of October 14, just days before Operation IceBridge discovered it.
The notorious geometric iceberg gleamed brightly, but only briefly. NASA says it has moved into the open water where it would melt in the warmer environment.
