NASA has spotted a second strikingly rectangular iceberg in Antarctica.
Scientists photographed the phenomenon, known as a 'tabular' iceberg, during an aerial survey named Operation IceBridge last week.
The second berg was spotted close to the first during the same survey, near to the Larsen C ice shelf, NASA has revealed.
IceBridge senior support scientist Jeremy Harbeck pictured the two icebergs together on the airborne survey of the Earth's polar ice on October 16.
The second iceberg is slightly less rectangular than the first, but has noticeably straight edges and corners.
Operation IceBridge is an ongoing NASA mission to monitor changes in polar ice.
NASA shared an image of the first iceberg, which features sharp angles and a flat surface, on social media last week.
“I thought it was pretty interesting; I often see icebergs with relatively straight edges, but I've not really seen one before with two corners at such right angles like this one had,” Mr Harbeck said in a statement.
The iceberg appeared to be freshly calved from Larsen C, which in July 2017 released the massive A68 iceberg, a chunk of ice about twice the size of Luxembourg.
On Tuesday, it emerged that Mr Harbeck had spotted two rectangular icebergs on the same flyover.
In the new photo, Mr Barbeck captured both the edge of the now-famous iceberg, and a slightly less rectangular iceberg.
The image also captures A68 in the distance.
Mr Harbeck added: “I was actually more interested in capturing the A68 iceberg that we were about to fly over, but I thought this rectangular iceberg was visually interesting and fairly photogenic, so on a lark, I just took a couple photos."
The flight originated from Punta Arenas, Chile, as part of a five-week-long IceBridge deployment, which began October 10 and is scheduled to conclude November 18.
