NASA photographed the unusual object in Antarctica last week as part of Operation IceBridge.
Nasa had found a piece of floating ice in Antarctica that is so flawless, it looks like it was deliberately cut. "And then you have what are called 'tabular icebergs'".
The striking iceberg isn't the only perfectly shaped formation scientists came across on their flight over the Atlantic last week, with NASA also sharing images online of a triangular berg found in the Weddell Sea.
Lieser said the straight lines are due to the structure of the snow crystals, and how they break apart and react to stresses.
A NASA spokesman said: "It will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice".

EDT (2030 GMT) on Tuesday, and the Energy Information Administration (EIA) report on Wednesday morning. Global crude prices have fallen below their 50-day moving average for the first time since August.
"In addition, IceBridge collects critical data used to predict the response of Earth's polar ice to climate change and resulting sea-level rise". This berg hasn't been measured yet, but Brunt says it's about one mile across, which isn't not particularly large.
Last year, a giant iceberg the size of DE - named A-68 - broke off from Larsen C, fuelling concerns it could be on the brink of collapse.
While the rectangular ice might look a little unreal, they're still just a natural part of the process of icebergs breaking off the Larsen C ice shelf in Antarctica.
Brunt observed that the square-like iceberg appeared new at the time because its edges still looked sharp-signs that wind and water had not done their jobs of eroding the iceberg's surface.
But, he added that "the presence of icebergs like these are a sign of increased calving". Larsen A collapsed in 1995, and Larsen B collapsed in 2002.
"I thought it was pretty interesting", Dr. Harbeck said. Though icebergs often calve off, a portion of that ice is replaced by snowfall.
