Journalist's death was 'plot gone awry', Trump says

Massive, perfectly rectangular iceberg discovered

A gigantic and perfectly rectangular iceberg has been spotted in the Antarctic by NASA scientists.

The enormous block of ice, known as a Tabular berg, is thought to be a mile in length, experts said.

It was found off the east coast of the Antarctic Peninsula, near the Larsen C ice shelf, by scientists flying over the region last week.

The iceberg’s sharp angles and flat surface suggest it was recently calved from the ice shelf, NASA Ice researchers said.

Scientists took the image as part a study into the calving process of icebergs as a way of measuring melting due to global warning.
